HFL0308-KF INA Drawn Cup Needle Roller Clutch 3x6.5x8

Drawn cup needle roller clutches are one-way clutches comprising thin-walled, drawn outer rings with a series of ramps on the inside diameter. They can transmit high torques in one direction and are compact in a radial direction. They give very precise indexing since the individual spring loading of the needle rollers ensures continuous contact between the shaft, needle rollers and ramps. Roller clutches with a knurled outside surface  have the suffix R and are suitable for use with plastic housings.

Typical applications including: indexing clutches, back-stopping clutches, and overrunning  clutches.

• HF - Steel Springs
