7206C-5GLX2 Single Row 15° P4 Duplex Angular Contact Ball Bearing Light Preload 30x62x16mm CNC Spindle Equipment

The CSK25M integrated sprag one-way clutch bearing is combined with standard 6205 deep groove ball bearing, equipped with inner keyway for torque transmission. It locks torque in single rotation direction and freewheels reversely, ideal for overrunning, indexing and anti-reverse braking.
It is widely used in conveyors, packaging machines and textile equipment where reverse rotation prevention and stable one-way power transfer are required.
