High Torque One-Way Bearings

High torque one-way bearings, also known as sprag clutches, allow shafts to rotate freely in one direction while locking in the other to handle backstopping or overload protection. These types of bearings are built to handle heavy loads and fast speeds without wearing out. GMN’s high torque bearing line is German-engineered for exactly that, offering a range of reliable, easy-to-integrate options designed for strength, speed, and long service life.

Find the Right One-Way Bearing

If you don’t know the difference between all our complete clutch units (FPD, FND, RA, FP and FN) we can help.

Answer these two questions to find the high torque one-way bearing that’s best for your application.

P.S. You can skip this & contact an engineer to find the right clutch.

1. Do You Need an Inner Ring Keyway?

If Yes! Then check out these products:

FND Series: RPM: 1,000 to 1,700 | Torque: 161 to 588 Nm (comes w/ seals & keyway)
FN Series: RPM: 2,500 to 4,800 | Torque: 160 to 588 Nm (no seals)
RA Series: RPM: 1,000 to 1,700 | Torque: 161 to 543 Nm (w/ mounting tab)

Our inner ring keyway is designed for a light press fit to support torque transfer.

2. Do You Need Rubber Seals?

If Yes! Then check out these products:

FPD Series: RPM: 1,000 to 2,000 | Torque: 84 to 588 Nm (no keyway)
FND Series: RPM: 1,000 to 1,700 | Torque: 161 to 588 Nm (comes w/ seals & keyway)

Effective round, rubber seals protect the one-way clutch bearing from external contamination and keep oil inside.

3. No Keyway & No Rubber Seals?

If this is you, then check out this product:

FP Series: RPM: 2,500 to 10,100 | Torque: 53 to 588 Nm
