HFL one-way bearing

HFL is an integrated one-way bearing with a stamped outer ring needle roller clutch and two side support bearings. The core is "one-way locking+two-way radial support", without an inner ring or a full needle cage. It uses the shaft neck as the inner raceway and relies on needle rollers and springs to achieve one-way torque transmission and reverse idling. It is suitable for low-speed light medium load scenarios that require radial support and anti reversal. It can be positioned by pressing the seat hole without the need for additional axial fixation.
