CSK25 One-Way Clutch Bearing - Sprag Freewheel Backstop

CSK25 One-Way Clutch Bearing – Sprag Freewheel Backstop
✔️  25mm x 52mm x 15mm – Torque-Locking in One Direction

The CSK25 is a high-performance one-way clutch bearing designed to transmit torque in a single direction while allowing free rotation in the opposite. Utilizing a sprag freewheel mechanism, it acts as an overrun clutch or backstop in applications like conveyors, printing presses, hydraulic drives, and mining equipment.

✅ Inner diameter (ID): 25mm
✅ Outer diameter (OD): 52mm
✅ Width: 15mm
✅ Torque capacity: 68 N·m
✅ Application: Prevents reverse rotation during power loss
✅ Brand: VXB Bearing
✅ Quantity: 1 bearing

💡 How do sprag clutches maintain rotational integrity under reverse loads?
Sprag elements inside the bearing wedge between inner and outer races under reverse torque, locking the system instantly - delivering zero-backlash performance essential for safety in driven and load-holding systems.

Engineered to engage only when it matters - ideal for backstopping and overrunning applications.

💡 When is a one-way clutch bearing essential?
Answer: It’s critical in systems where back-driving could cause damage, product loss, or safety hazards - like conveyor belts on an incline or industrial machinery requiring unidirectional motion.
