Adjustable speed drives alter the speed of a driven shaft to a speed selected by an operator.

Roller chain sprockets engage chain drives in power transmission and conveyor systems, though sprockets can engage any perforated material. Chain drives can be highly efficient and can produce a mechanical advantage as speed reducers/increasers. Sprockets conforming to ANSI standard B 29.1 are not meant to engage roller chains of any other parameter. ANSI conforming roller chain is smaller and somewhat weaker than its European counterpart.

Flat belts are used in transmission and conveying systems. They feature transmission efficiency, cost effectiveness and ease of installation and use. Typical belt applications include conveyors, machine tools, and heavy industrial equipment.

Flexible couplings connect rotating members while allowing some degree of angular or parallel misalignment.

Flexible shafts provide rotary power transmission along curved or adjustable axes. They are used in a wide variety of remote control, valve actuation, and power transmission applications.

Fluid couplings are torque-transmitting couplings that use hydraulic oil or water to transmit power. They differ from torque converters in that the input torque is equal to the output torque (no multiplication of torque).

Flywheels have a high mass and are connected to a rotating shaft that smoothes the delivery of torque, or turning power, from a motor or engine. The inertia of flywheels allows them to absorb and release energy with little change in speed.

Gearboxes and gearheads, also called gear reducers or speed reducers, are power transmission devices that use a gear arrangement in an enclosed housing to transfer energy, increase torque and reduce speed from one device to another. Gearboxes may also be referred to as gear reducers or speed reducers.

Includes all power transmission gear types, geometry and materials, including English and metric designs.

Idler pulleys are used to take up slack, change the direction of transmission, or provide clutching action.

Index drives are used to start and stop a table, conveyor or other equipment at precise intervals. Types of index drives include cam index drives, ring index drives, and roller gear index drives.

Roller chain sprockets engage chain drives in power transmission and conveyor systems, though sprockets can engage any perforated material. Chain drives can produce a mechanical advantage as speed reducers/increasers. ISO sprockets are designed to engage British Standard Chain and conform to ISO standard R606. These sprockets are not interchangable with ANSI defined sprockets.

Leaf chain is a rollerless chain that is commonly used on forklift trucks and in other material handling applications.

Linear shafts are elongated, rod-shaped devices that provide linear or rotary motion for power transmission applications.

Line-shaft spools are mounted to the drive shaft of a line-shaft conveyor. A belt transmits power from the spool to drive individual conveyor rollers.

Mechanical feedthroughs transmit mechanical motion through the walls of a vacuum system. Both linear and rotary feedthroughs are included in this grouping.

Power take-offs (PTOs) are extensions of a vehicle's drive train that can be engaged to power auxiliary equipment such as plows, augers, winches, and many other material handling, construction, and agricultural implements.

Precision locknuts are used to secure bearings, gears, and other power transmission products to shafts and spindles.

Precision shafting provides the highest degree of overall accuracy, concentricity, straightness and surface perfection attainable in commercial practice.

Ratchets and pawls are mechanical gearing used to transmit intermittent rotary motion. They permit a shaft to rotate in one direction, but not in the opposite one.

Rigid couplings connect rotating members such as shafts. They secure onto both members and provide transmission of torque and motion.

Roller chain is used in power transmission applications. Products are characterized by ANSI and BS/DIN standard sizes.

Rotary shafts are elongated, rod-shaped devices that rotate about a longitudinal axis and transmit torque. They are similar in shape to linear shafts, but are designed to withstand torsional forces.

Round belt or pulleys are used in mechanical lifts and transmissions with o-rings, round belts, cables, ropes, or wires.

Round belts and o-ring belts are light-to-medium duty power transmission belts. They can be solid or hollow, and can easily be used in 3-D applications.

Shaft collars attach to shafts and are used as stop features or targets for devices such as tachometers.

Shaft-hub locking devices frictionally clamp gears, pulleys, flywheels, and other components to a shaft without the need for threads or keys.

Silent chain or inverted-tooth chain features teeth on its links that engage the sprocket teeth.  Silent chain can be wide and is used in a variety of power transmission and conveying applications.

Slewing drives are a type of special gearbox designed to translate axial movement, typically of a worm gear, to radial movement. Typical applications of slewing drives include wind turbines, solar tracking systems, satellite broadcasting systems aerospac

A spline shafts has grooves or tongues machined along its length for torque transmission or anti-rotation linear guide applications.

English pitch timing belts mate with same-pitch timing pulleys in power transmission systems where maintenance of speed ratio is an important design consideration. English pitch is the distance between belt teeth based on inches (in).

Metric pitch timing belts mate with same-pitch timing pulleys in power transmission systems where maintenance-of-speed ratio is an important design consideration. Metric pitch is the distance between belt teeth based on millimeters (mm).

Timing pulley flanges are used to maintain belt contact with a pulley in a transmission application.

Timing pulleys mesh with same-pitch timing belts on synchronous drives where maintenance of speed ratio is important. These pulleys have an inch-based pitch designation.

Timing pulleys mesh with same-pitch timing belts on synchronous drives where maintenance of speed ratio is important. These pulleys have a millimeter-based pitch designation.

Universal joints are flexible mechanical connections used to transmit rotary motion from one shaft to another shaft that is not in line with the first, or when alignment varies during service.

Variable transmissions are used in industrial applications to alter the speed of an output shaft.

V-belt pulleys or sheaves mate with drive belts in numerous power transmission applications. They are made in many configurations such as tension idlers and variable speed/ratio pulleys.
