CSK 40*80*18 PP | One Way Lock Bearing

The CSK 40 PP is a precision one-way sprag clutch bearing designed for applications that require rotation in only one direction while preventing reverse movement. Built with a 40 mm inner diameter, 80 mm outer diameter, and a sturdy 22 mm width, this bearing provides high torque transmission and reliable performance under demanding industrial conditions. Manufactured from hardened chrome steel, the CSK 40 PP offers excellent durability, resistance to wear, and long service life even under continuous or high-load operation. Its PP configuration includes a keyway on both the inner and outer race, ensuring secure mounting to both shaft and housing for maximum torque stability. This one-direction freewheel bearing is commonly used in conveyors, packaging machinery, printing equipment, indexing mechanisms, and back-stop or overrunning applications where smooth directional control is essential.
