Looking to build your own one way sprag clutch bearing? We have the part you need! This bearing is typically used in automatic transition applications where engaging and disengaging is needed. This bearing does not have actual ball bearings, but more like “hour glass” shaped bearings that engage when turned a certain way. This piece sits inside a shaft and turn along with the housing. We offer several sizes. The featured bearing is 38.092mm x 54.752mm x 8.330mm and is composed of chrome steel.
