Sprockets, roller chain, metric engage chains in many different power transmission and conveyor systems. Chain drives are often used as economic, reliable drive systems for long running, continuous drive applications with limited shock and torque loads. Metric sprockets are classified according to ISO number designations. Sprockets engage chains in many different power transmission and conveyor systems. Chain drives are often used as economic, reliable drive systems for long running, continuous drive applications with limited shock and torque loads. English sprockets are classified according to ANSI number designations.
Pitch is the distance between adjacent tooth centers. Metric roller chain and sprockets are categorized according to ISO Standard 606. The number correlates to pitch in 1/16" increments, expressed in millimeter units. AN ISO 12 sprocket therefore mates with a chain with 3/4", or 19.05mm, pitch. Important dimensions to consider when searching for sprockets, roller chain, metric include number of teeth, bore diameter, hub diameter, outside diameter, length through bore, and weight. Number of teeth for a specified pitch will determine sprocket size and drive ratio. The bore diameter is the diameter of center bore for shaft mounting. The hub diameter is the outside diameter of desired hub. The outside diameter is the diameter of the sprocket including teeth. It is primarily of concern if clearance is an issue. The length through bore is the total width of the sprocket, including hub(s).
Material selection is dependent on factors such as required power transmission and speed, environmental factors such as temperature and exposure to corrosive elements, and other factors such as noise generation. Consult with a sprocket manufacturer on a specific application to optimize material selection. Common material choices for sprockets, roller chain, metric include all plastic, plastic teeth with a metal insert, standard steel, hardened steel, and stainless steel. The sprocket style can be single, double, triple, quadruple, and quintuple or higher. A single style sprocket has one sprocket on one hub. A double style sprocket has two sprockets on one hub, and so on. Some sprockets are idler sprockets. Idler sprockets rotate freely while taking up slack and providing tension to a chain drive system. They are used as tensioners and occasionally to provide chain clearance around a machine component. The idler style can be bronze bushing or ball bearing.
The hub style on sprockets, roller chain, metric can be Type A (hubless), Type B (hub on one side), Type C (hub on both sides), and Type D (detachable bolt-on hub). Specialty hubs include tapered bushing, and shear pin hub. Tapered bushings are tightened down onto the shaft like a collet to minimize shaft marring. Shear pin provides protection against drive system jamming or overload. Torque is carried by shear pin, which is necked to shear when safe load is exceeded. Shaft mounting choices for sprockets, roller chain, metric include set screws, keyway, and simple bore. An important environmental parameter to consider is the operating temperature. |

Shaft collars attach to shafts and are used as stop features or targets for devices such as tachometers. They are usually made of aluminum, steel, stainless steel, or alloyed steel and coated with zinc, chromium or black oxide. Shaft collars made from non-metallic materials such as nylon are also available. Generally, these products are used for washdown applications such as food processing. There are several basic shaft collar designs. Setscrew collars are suitable for simple shaft positioning, but are not designed for high axial loads or applications that require repositioning. Threaded clamp collars are designed for threaded shafts and provide a relatively high axial loading force. One-piece clamp or C-style collars provide a more uniform holding force on the shaft. Like threaded clamp collars, these devices can be repositioned as necessary. Two-piece shaft collars provide a stronger and more uniform holding force than one-piece shaft collars. They also accept greater variances in shaft diameter and can be assembled anywhere on a shaft.
Selecting shaft collars requires an analysis of specifications. Products are measured in English units such as inches (in) or metric units such as millimeters (mm) or centimeters (cm). Thread types include unified national fine (UNF), unified national coarse (UNC), and acme. Width, bore diameter, outer diameter, and axial load capacity are important considerations when specifying shaft collars. Measured in pounds (lbs) or kilograms (kg), axial load capacity is the maximum load that can be applied along or parallel to and concentric with the primary axis. Typically, acme threaded collars can withstand higher thrust loads than conventional smooth bore collars. Some shaft collars include clamping screws that are all inserted from the same direction. Others include clamping screws that are inserted from opposite directions.
Shaft collars are used in a variety of application and industries. Examples include agricultural implements, office machines, exercise equipment, mixers, and printing presses. A variety of specialized products are available. Knurled shaft collars provide a friction surface for hand gripping and are suitable for conveyors and other applications which require frequent collar adjustment. Hexagonal-bore shaft collars are suitable for power transmission and drive applications. Heavy-duty shaft collars feature large cross sections and sturdy clamping screws for added holding power. Because heavy-duty shaft collars provide better vibration and shock resistance, they are designed for applications such as off-road, mining, paper and steel mill equipment.

Round belts and o-ring belts are light-to-medium duty belts used in power transmission applications. Round belts are solid or hollow and vary in terms of weight and size. They use friction to stay in contact with round belt pulleys and must be stretched or elongated to provide proper driving tension. O-ring belts (endless round belts, endless drive belts) also vary in weight and size, but do not require a belt tensioner. They can be used with both round belt pulleys and V-belt pulleys. Most o-ring belts are made of materials that are resistant to chemicals and compounds such as oxygen, ozone, oils, and grease. They can be cleaned easily and resist abrasion and marking. Belts that are heat-sealed do not require tooling changes. Most round belts and o-ring belts are between 1/16 in. and 3/4 in. wide and at least 3 ft. long, depending on the size of the cross-section. Some products have tensile strengths of up to 8,000 psi and a temperature resistance that ranges from
- 60° F to 225 F°.
Specifications for round belts and o-ring belts include cross-sectional diameter, length, working tension, operating temperature, belt material, and reinforcement material. Belt materials vary in terms of strength, elasticity, and power transmission capabilities. Nitrile is used across a wide range of temperatures and provides good resistance to petroleum hydrocarbons and fuels. Leather absorbs lubricants and provides effective sealing against rough surfaces. Neoprene is a synthetic material with outstanding physical toughness. Polyurethane is flexible and offers good abrasion resistance. Polyvinyl chloride (PVC) is smooth, flexible, non-toxic, and often rated for use in food processing applications. Round belts and o-ring belts that are made of rubber usually contain natural compounds such as polyisoprene. Reinforcement materials include fiberglass, polyester and steel, as well as proprietary products such as Kevlar®, a registered trademark of DuPont.
Round belts and o-ring belts vary in terms of application and features. Some products are suitable for industrial applications such as weighing, bagging, sorting, bottling, gluing, sealing, pulling, and shrink-wrapping. Others are used in live roller conveyors such as line shaft conveyors and powered roller conveyors. The printing industry uses round belts and o-ring belts in collating, sorting, folding, and imaging equipment. Round belts and o-ring belts are also used in office equipment such as photocopiers and printers. In terms of features, some round belts and o-ring belts prevent the buildup of static electricity or resist damage from ultraviolet (UV) light. Belts that are supplied as rolls may be cut and spliced to desired lengths. Belts that carry approvals from agencies such as the U.S. Department of Agriculture (USDA) or Food and Drug Administration (FDA) are also available.

Roller chains are used in power transmission design of all kinds and in many specialized industries. Roller chain configurations include standard, heavy duty, double pitch for light loads, attachment options and many application-specific geometries. There are many styles of chain; those covered in this search form is characterized by ANSI and BS/DIN standard sizes.
The American National Standards Institute (ANSI) governs number designations for roller chain pitch. English roller chain and sprockets are categorized according to ANSI B 29.1M. The number can be used to identify pitch in the following way: the first digits identify the pitch in 1/8" increments, and the last digit is 0 for standard proportions, 1 for lightweight chain, and 5 for rollerless bushed chain. A #41 sprocket is therefore for 1/2"-pitch lightweight chain, a #120 sprocket is for 1-1/2" pitch chain, etc. British Standard / DIN / International Standards Organization (ISO) designations are governed by European standards committees. Metric roller chain and sprockets are categorized according to ISO Standard 606. The number correlates to pitch in 1/16" increments, expressed in millimeter units. AN ISO 12 sprocket therefore mates with a chain with 3/4", or 19.05mm, pitch.
Standard configurations for roller chain include single, double, triple, quadruple, and quintuple or higher. A single configuration has one chain strand. A double configuration has two chain strands, and so on. Roller chain comes in a wide variety of metal and plastic materials. Many factors such as cost, environmental conditions, noise and heat generation and design horsepower transmission influence the best material choice. Consult a chain manufacturer on a specific application for material optimization. Common materials of construction include steel or hardened steel, stainless steel, nylon, acetal, polypropylene, and plastic or metal combination.
Common features for roller chain include attachment chain, double pitch, oversized roller, rollerless, offset link, heavy duty, self-lubricating, corrosion resistant, and flexible. Some roller chain has an attachment type. These can include standard straight, standard bent, wide contour straight, wide contour bent, and extended pins. Specialty applications for roller chain include oil-field chain, bindery chain, lift chain, pin oven chain, film feeder chain, and coupling chain.
Important mechanical specifications to consider when searching for roller chain include tensile strength, maximum allowable load, and chain weight. Tensile strength is the ultimate failure tension load of a chain. The maximum allowable load is the tension for which chain is rated to carry in running operation. Chain weight is specified in weight per unit length. It varies with pitch and special construction techniques. An important environmental parameter to consider is the operating temperature. |

Rigid couplings connect rotating members such as shafts and transmit torque and motion. Most rigid couplings are made of aluminum, steel, or stainless steel. There are several basic types of products. One-piece set screw devices are solid, O-shaped couplings that attach to shafts with set screws. One-piece clamp couplings are solid, C-shaped devices with a split that is closed with tightening screws. Two-piece clamps are split axially into two pieces, each of which is closed onto the shaft with tightening screws. Multi-screw couplings are commonly available. Typically, all of the screws are inserted from the same direction. Shrink discs are rigid couplings with two external rings that tighten together axially and exert inward force on a third ring via tapered surfaces. This closes the inner ring onto the shafts and provides a secure connection. Rigid couplings with keyways include keys that can be used to stop the rotation of the shaft couplings.
Mechanical properties for rigid couplings include rated torque, rated speed, torsional stiffness, and backlash. Rated torque is the maximum service torque for which the device is rated. Rated speed is the maximum rated rotational speed of the coupling. Stiffness is expressed in torque per units of angular deformation (degrees). Backlash, the rotational position loss due to a change, is also measured in degrees. Important dimensions to consider include bore diameter, coupling diameter, coupling length, and design units. Bore diameter is the internal diameter for mating to the shaft-end. Coupling diameter is the outside diameter (OD), a measurement which includes the housing. Design units are English measurements such as inches (in) or metric measurements such as centimeters (cm). For rigid couplings with one or more keyways, keyway width is an additional consideration.
Alignment and motion parameters to consider when specifying rigid couplings include angular misalignment tolerance, parallel misalignment tolerance, and axial motion allowed. Angular misalignment tolerance is the maximum angular misalignment between coupled shafts that rigid couplings can accommodate. Similarly, parallel misalignment tolerance is the maximum parallel offset between shafts that rigid couplings can accommodate. Axial motion allowed refers to the relative axial motion allowed by the coupler between two shafts. |

Linear shafts are elongated, rod-shaped devices that provide linear or rotary motion for power transmission applications. They are used as axles, pistons, and rollers in heavy machinery. Some linear shafts have axial or radial holes for mounting to support structures. Others are grooved for the placement of snap rings or channeled for keyways. Solid or hollow linear shafts with male or female threads and stepped or chamfered ends are also available. Most linear shafts are made of aluminum, alloy steel, carbon steel, stainless steel, composite materials, or plastics. Alloy steel is harder than carbon steel and provides superior durability. Stainless steel is well-suited for applications in which corrosion resistance is an important consideration. Aluminum linear shafts provide good electrical and thermal conductivity, high reflectivity, and resistance to oxidation. Composite materials are often made of carbon fibers bonded together by resins. They are not as strong as metal shafts, but are lightweight and help reduce energy requirements.
Linear shafts are usually coated or hardened to improve durability. Anodizing is a protective surface coating process used mainly with aluminum products. Black oxide coatings are applied to steel or stainless steel shafts to prevent ion corrosion. Ceramic coatings provide a wear-resistant finish while chromium coatings improve corrosion resistance and reduce friction. Linear shafts with nickel or nitride coatings are also available. Teflon®, a registered trademark of DuPont Dow Elastomers, is a class of fluoropolymer resins that is resistant to high temperatures, chemical reactions, corrosion, and stress cracking. Linear shafts that are coated with PTFE are used in a variety of applications. Some steel shafts are case-hardened with carbon or nitrogen. Others are through-hardened to ensure that the entire shaft has the same hardness.
There are several ways to measure the hardness of linear shafts. The Rockwell hardness test presses a steel or diamond cone against a test sample and measures the depth of the resulting indentation. Higher measurements indicate harder materials. For linear shafts, common Rockwell hardness ranges are 50 to 59, 60 to 69, and 70 to 79. The Brinell hardness test subjects a test material to a load of 3000 kg with a hardened steel or carbide ball that is 10 mm in diameter. The Knoop hardness test also measures a material’s hardness through its resistance to indentation. The Vickers hardness test indents a test material with a diamond indenter that is shaped into a right pyramid with a square base and an angle of 136° between opposite faces.
Important specifications for linear shafts include shaft diameter or width, maximum length, weight, height, and tolerance. Most linear shafts have circular or square cross sections and are produced in standard lengths that can be cut to size for specific applications. Weight is measured in per unit distance, typically pounds per feet. Height is the distance from the guide or rail base to the center of the guide or rail. Ultra precision shafts have a very tight tolerance. Standard grade and precision grade linear shafts are also available. |

Flat belts are used in power transmission and conveying systems. They are noted for their power transmission efficiency, cost effectiveness and ease of installation and use. Typical applications include conveyors, compressors, machine tools, and other heavy industrial equipment.
When comparing flat belt drives to V-belt drives, there are advantages to using flat belts. The small bending cross-section of the flat belt causes little bending loss. This fact, coupled with even running and the absence of pulley wedge effects, leads to higher flat belt efficiency. The maximum possible efficiency attained by flat belts is 98%. The gain in efficiency also leads to corresponding savings in energy compared to V-belt a fact that has been proven during practical trials. Service life may also be better for flat belt drives. In flat belt drives, the belt is frictionally engaged on the outer pulley diameter, not on the lateral wedge surfaces as in the case of the 'V' belt drive as a result the wear on the belts and pulleys are less in flat belts. Also, if several 'V' belts run on one drive, they wear unevenly due to production allowances. V-Belts are often tensioned haphazardly i.e., until the individual belts no longer wobble, flat belts can be installed very simply and securely. Belts are tensioned to the calculated initial tension by means of simple measuring marks to be applied to the belt.
Flat belts are manufactured using widely varying components and designs. Materials used in the design of flat belts may include aramid, rubber, cotton or canvas, EPDM, steel, and urethane, among others. The material in use can greatly affect the performance of the belting system and help to determine the types of applications with which it should be used. The properties of various rubber materials may be sensitive to temperature or other extreme operating environments, which may change the characteristics of the material.
Flat belts generally have a traction layer made of oriented polyamide with two covers of elastomer leather or textiles material and one intermediate layer of fabric on each side. The traction layer absorbs the forces exerted on the belt when power is transmitted. The friction cover ensures that the peripheral force acting on the belt pulleys is transmitted to the belt and vice-versa.
Flat belts may be customized for a wide range of applications. Such configurations include an incline to carry product to another level. Flat belts may also have a tracking sleeve under the system to ensure that the belt does not slip, or that the coefficient of friction can be adjusted to prevent slippage. |

Belt and chain tensioners reduce belt or chain slack and transmit drive torque uniformly. They also reduce noise and vibration; decrease sprocket, pulley, belt, and chain wear; and increase the life of drive components. In drives, belts and chains are installed with enough tension to create a level of friction that causes the belts or chains to grip the pulleys and the pulleys to turn. Most belt drives consist of flat leather, rubber, or fabric belts running on cylindrical pulleys, or belts with a V-shaped cross section running on grooved pulleys. V-belts require less tension than flat belts because their greater surface area creates more friction. Chain drives that use sprockets are reliable systems for long running, continuous drive applications with limited shock and torque loads.
Some belt and chain tensioners are fixed in place after installation, while others provide various means of adjustment. Manual belt and chain tensioners require operators to adjust screws or unbolt and reposition parts. Spring-loaded tensioners automatically maintain tension as belts or chains wear and stretch. Floating tensioners are mounted on chains and belts, typically with two opposing pulleys or sprockets. Tension rings spin with the drive and mount either inside the belt or chain, or between the drive and the driven pulley or sockets. Belt and chain tensioners sometimes specify the maximum tension rated to maintain in the drive; however, not all tensioners carry this rating. End-of-travel limit switches for floating or spring-loaded tensioners indicate when a tensioner has run out of adjustment and may require repositioning.
Belt and chain tensioners are available in a variety of sizes, styles, and materials. They can handle different minimum and maximum loads as well as temperatures. With chain drives, maximum chain pitch is an additional consideration. Belt and chain tensioners are used in machinery and equipment, automobiles, bicycles, conveyor belts, and numerous other applications. |

Adjustable speed drives change the speed of a driven shaft to a speed selected by the operator. Additionally, these drives are used to maintain the speed of a machine to very close tolerances: ±0.1% is not uncommon. This is much more accurate than the speed control offered by conventional AC motors, which can vary 3% from no load to full. Important performance specifications to consider when searching for adjustable speed drives include output shaft speed, output torque, continuous output power, and speed control. The output shaft speed is the no load rotational speed of output shaft at rated terminal voltage. Output torque describes the torque capability of the drive under constant running conditions. The continuous output power is the mechanical power provided by the drive output. Choices for speed control include handwheel, lever, screw, electric, and solid-state.
Choices for drive types for adjustable speed drives include traction drives, belt and chain drives, gear drives or differentials, hydraulic drives, eddy current drives, and magnetic coupling. Traction drives depend upon friction between a speed adjusting mechanism and specially shaped input and output plates to achieve adjustable speed with relatively high efficiency. Belt and train drives operate with adjustable diameter sheaves or pulleys. Gear drives are the most durable, rugged, and efficient of all adjustable-speed drives, but they are capable of providing only a specific number of fixed gear ratios. In a hydraulic drive there are two main methods of hydraulically varying the speed of the driven load when the driving motor is operating at a constant speed, fluid coupling and hydraulic pump and motor. An eddy current drive is an adjustable speed drives in which a constant speed AC motor drives a drum assembly. In a magnetic coupling drive the magnetic coupling replaces the physical connection between motors and loads with a gap of air. The output shaft position on hydraulic drives can be horizontal, vertical up, or vertical down. Shaft orientation choices include in-line, offset parallel, and right angle. Mounting choices are base or flange.
Adjustable speed drives can have an integrated motor in a packaged configuration. The "packaged" drive consists of the adjustable speed section and an electric motor. The unit may also include a geared reducer. Choices for motor input include 115/120V 60 Hz, 208-230 / 240V 60 Hz, 460 / 480V 60 Hz, 575 / 600V 60 Hz, 50 Hz / International Power, DC motor, and hydraulic motor. The phase for adjustable speed drives can be single or three phase. Common features for adjustable speed drives include integrated gears, continuously variable, C-flange adapters, hollow shaft, speed feedback, and reversible. Motor enclosure options include open frame or frameless, drip-proof, dust-proof, and totally enclosed. Special or extreme environments that adjustable speed drives can be configured for include cleanroom, cryogenic, explosion-proof, radiation hardened, vacuum use, and washdown duty. |
