Brief Introduction of SF Overrunning Clutch One Way Bearings 


Type SF Series one-way clutch is a compact and reliable overrunning component designed for single-direction torque transmission. 


Using a roller-wedging mechanism, it delivers positive drive in one direction while freewheeling in the opposite direction to ensure safe and efficient operation. 


This series features high load capacity, low friction, fast response, and long service life. It is widely used in packaging machinery, conveyor systems, textile equipment, gear reducers, and automation drives for backstopping, overrunning, and indexing functions. 


With precision rollers and hardened races, the SF Series maintains stable performance under high speed, heavy load, and frequent start-stop conditions. 


It also supports multiple mounting and lubrication options to suit various applications, providing a durable, low-maintenance, and dependable power-transmission solution.
