CSK20 One-Way Clutch Ball Bearing - 20mm Sprag Freewheel Backstop

CSK20 One-Way Clutch Ball Bearing - 20x47x14mm 
Sprag Freewheel Backstop

The CSK20 one-way clutch bearing is made for applications where rotation should happen in only one direction. It works like a freewheel or backstop, letting shafts spin forward while locking instantly if they try to reverse. This type of bearing is commonly used in conveyors, textile machines, printing presses, washing machines, and any setup where rollback could cause damage - like during a power outage.

With a 20mm inner diameter, 47mm outer diameter, and 14mm width, this bearing is compact but tough, offering up to 40 N·m of torque.

💡 Customer Tip - When should I use a one-way bearing?
Answer: Use it when you need motion in just one direction - like on a conveyor that shouldn't roll backward if power cuts off. It’s perfect for preventing damage from gravity or sudden stops.
