Custom Pulley Adapters Manufacturer
Pulley adapters customize a pulley's bore for a perfect fit on a shaft. Retlaw Industries manufactures drive, shoulder, clevis and bore adapters from high-performance thermoplastics at our ISO 9001:2015 certified facility in Wisconsin. Our adapters feature precision ABEC-1 bearings for high-speed use.
Common Pulley Adapter Types
Retlaw Industries manufactures adapters in a range of bore diameters, widths and standoff sizes. Common pulley adapters our team creates include drive adapters, shoulder adapters, clevis adapters and standard bore adapters. If you can't find the right size or style in our inventory, our designers will collaborate with you to produce a custom adapter for your specific application.
What is a Drive Adapter Used For?
A drive adapter is used to convert an idler pulley into a drive pulley. Manufactured from strong alloy steel, it uses a keyway to lock onto the drive shaft, directly transferring rotational power to the belt system. This is essential for power transmission.
Our Drive Adapter Specs
| PART NO. | SHAFT DIA. | STAND-OFF | KEYWAY |
|---|---|---|---|
| DA-38 | 0.375 | 0.375 | 0.125 |
| DA-50 | 0.5 | 0.375 | 0.188 |
| DA-63 | 0.625 | 0.375 | 0.188 |
| DA-75 | 0.75 | 0.375 | 0.188 |
| DA-100 | 1 | 0.375 | 0.25 |
What is a Shoulder Adapter?
A shoulder adapter is an idler bore adapter that features a standoff (or spacer) on one side of its center bore. This design provides critical clearance, allowing the pulley to operate without interference while improving the adapter's mounting versatility.

How Do Clevis Adapters Work?
A clevis adapter works by providing standoffs on both sides of the center bore. This creates balanced spacing on each side of the pulley, promoting better weight distribution and is ideal for systems using a clevis pin or fastener.

|---|---|---|---|
| CA-005P | 0.39 | 0.17 | 12mm |

| CA-07P | 0.381 | 0.76 | 12mm |
| CA-08P | 0.506 | 0.76 | 12mm |
What is a Standard Bore Adapter (Bushing)?
A standard bore adapter, also called a bushing, is a simple component that fits into a pulley's borehole to reduce its inner diameter. It ensures a perfect fit on a smaller shaft and does not have any standoffs.

| BA-01P | 0.381 | 17mm | 12mm |
| BA-001P | 0.39 | 15mm | 10.85mm |
