How a Sprag Clutch Works
A sprag clutch looks like a roller bearing, but instead of allowing the elements to roll freely in both directions, they lock when rolled in the opposite direction. Sounds simple enough, right? Well, there is a whole lot that goes into the functionality of a one-way bearing. Read More…
Ceramic Ball Bearings
Ceramic ball bearings (also known as hybrid bearings) are the one component that’ll easily optimize the performance of your application. The ceramic balls are made out of silicon nitride (Si3N4) and they offer lots of key advantages, find out in this article: Ceramic Balls in a Bearing
Angular Contact Bearing Selection Guide
The sprag clutch consists of a series of cam shaped steel wedges (or sprags). Each sprag is placed at an angle to allow rotation in one direction but provides instantaneous locking when force is applied in the opposite direction.How a Sprag Clutch Works by GMN Bearing USA

A one-way sprag clutch, sometimes called a “freewheel clutch,” allows rotation in one direction and instantly prevents force from being driven in the opposite direction.
Our GMN one-way sprag clutch products have a very compact design that maximizes the absorption of torque. Read More
