CSK20PP 1 Way 6204 Bearing with Keyway GCr15 Bearing Steel Clutch

CSK20PP 1 Way 6204 Bearing with Keyway GCr15 Bearing Steel Clutch

• This CSK20PP one-way bearing adopts standard dimension specification, with 20mm inner diameter, 47mm outer diameter and 14mm width. A built-in keyway is machined on the inner ring, which works together with matching flat keys to prevent relative rotation between the bearing and the installed shaft. This structural setup delivers reliable torque transmission when the unit rotates in the locking direction. Users can directly fit the bearing onto shafts of compatible size without extra modificati
• The bearing empty is manufactured from GCr15 bearing steel, a widely used alloy steel for rolling bearing production. The material contains balanced alloy components to support high contact stress generated by rolling elements while the bearing takes radial and partial axial loads. After proper heat treatment, the bearing ring and rolling elements gain uniform hardness, which resists surface deformation under cyclic contact pressure from repeated rotation. The raw material is refined to reduce i
• This CSK20PP component integrates one-way clutch function, which separates two rotation states: locking and overrunning. When the shaft spins in the locking direction, the internal sprag elements wedge tightly between the inner ring and outer ring to transfer torque and drive the outer assembly to rotate synchronously. When the shaft turns in the opposite overrunning direction, the sprags release the wedging state, allowing the inner ring to spin freely while the outer part stays stationary or r
• The bearing comes with PP sealing configuration on both sides. The side seals form a barrier to block fine dust, metal particles and debris from entering the internal raceway and sprag assembly during equipment operation. Keeping pullutions out reduces abrasive wear on rolling surfaces and wedge parts. The seal structure also slows down the loss of pre-filled lubricant inside the bearing cavity. Stable lubrication inside maintains smooth movement of internal wedge elements and rolling contacts
• This CSK20PP one-way clutch bearing fits multiple mechanical scenarios that need rotation direction control and torque transfer. Common installation cases include conveyor systems, small lifting machines, packaging equipment, textile machinery, and low-speed rotary automation devices. It can serve as an overrunning clutch for speed difference adjustment between two transmission parts, an indexing component for intermittent motion, or a backstop unit to prevent reverse rotation.
