One Way Sprocket Clutch

The simple construction of the Roller Clutch results in an easy-to-produce one-way clutch device that saves money for the user or OEM. Overrunning clutches are also known as free-wheeling or one-way clutches. In these roller-ramp clutches, engagement occurs with a wedging of the rollers between the inner cam and the outer housing. Torque capacity is nomially limited only by the contact stresses between the parts. Standard keyways are per ASA B17. 1.
