Rugged and Versatile Drive Adapters

Retlaw Industries provides the highest quality thermoplastic idler pulleys and sprockets on the market. In order to accommodate their wide range of applications, we also fit our pulleys with the best adapters so you can get the custom pulley system you need, performing just the way you need it to.

When you need a pulley for power transmission, you need a drive adapter. Drive adapters lock onto the drive shaft to turn the pulley and transfer mechanical power to the belt. Drive adapters replace the ball bearing component of our pulleys giving the idler wheel direct contact and responsiveness to the rotating shaft.

What are Drive Adapters Used For?

An idler pulley is one pulley in a set that drives the belt system of a vehicle. A drive pulley is a pulley that is attached to a power source. When in use, it puts force on a belt. Drive adapters are used to convert idler pulleys into drive pulleys. A key way connects the shaft to the adapter which transmits rotational kinetic energy to the pulley. Our drive pulleys have a standoff extending from one side of the bore. Drive adapters are manufactured using alloy steel for added strength and durability. Common applications for drive pulleys include reinforced nylon round, flat and V pulleys.

Drive Adapter Sizes

Our drive adapters come in multiple sizes, but our designers will work with you to produce adapters in custom sizes, if required.
