CSK Series bearings are a sprag spring type one way clutch bearing. Our 40mm CSK bearings features a keyway machined into the inner and outer race to prevent torque slip. This series of bearing only allows the shaft to turn in one direction and rotation is indicated by an arrow laser etched onto the inner race of the bearing. Each bearing comes lubricated with grease and ready to be mounted to the shaft.
