HF type unidirectional needle roller bearing

Stamped outer ring needle roller clutch is an extraterrestrial wheel clutch. Needle rollers are locking components. It consists of a thin-walled stamped outer ring, a retaining frame, a shaped spring embedded in the retaining frame, and a locking element roller needle installed in the retaining frame. The irregular spring ensures that the rolling needle always adheres to the precision. Commonly used in printing machinery, packaging machinery, textile machinery, food machinery, household appliances, light industry machinery, and testing equipment. The commonly used torque is 0.34N. m-121N. m, suitable for high speeds, generally ranging from 3900-34000r/min. The hardness of the shaft used by the user for this clutch should reach HRC58-62, and the dimensional accuracy and form tolerance should meet the requirements.
