Surplus New And Used Power Transmission Components

Power transmission components or drive components, are mechanical or electro-mechanical devices used in drive systems to transfer power (energy into motion), and often control speed,force, and direction of the motion. Power transmission components include couplings, gears, and belts. You can further refine your specific search using the category(ies) below:

Adjustable Speed Drives

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

English Pitch Timing Belts

English pitch timing belts are belts that mate with same-pitch timing pulleys in power transmission systems.

English Pitch Timing Pulleys

English pitch timing pulleys have a spacing or pitch based on inch (in.) measurements.

Flexible Couplings

Devices that are used to connect two rotating shafts together at their ends for the purpose of transmitting power, while permitting some degree of misalignment, end movement, or both.


Mechanical rotating machine parts with cut teeth or cogs that transmit power and motion between axes or shafts.

Idler Pulleys

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

Metric Pitch Timing Belts

Metric pitch timing belts are transmission belts that mate with same-pitch timing pulleys in power transmission systems.

Metric Pitch Timing Pulleys

Metric pitch timing pulleys have a spacing or pitch based on millimeter (mm) measurements.

Rigid Couplings

Rigid couplings connect rotating members such as shafts to provide transmission of torque and motion.

Rotary Shafts

Rotary shafts are elongated, cylindrically-shaped components that rotate on a longitudinal axis and are used to transmit torque.

Round Belts

Round belts are a circular cross section belt designed to run in a pulley with a 60 degree V-groove. 

Shaft Hub Locks

Shaft hub locks are devices that frictionally clamp components to a shaft without the need for threads or keys.

Spline Shafts

Spline shafts have either grooves or tongues machined along its length.

Universal Joints

Universal joints are flexible mechanical connections used to transmit rotary motion in misaligned shafts.

V-Belt Pulleys and Sheaves

V-belt pulleys and sheaves have one or more grooves and are designed for general-purpose transmission applications.

V-Belts and V-Ribbed Belts

V-belts and V-ribbed belts are power transmission drive belts with a triangular or trapezoidal cross section.

Wood Block Belts

Typically used with Reeves variable speed drives.
