Stieber Clutch GmbH GFRN-35 F5 F6 NSNBC01 Clutch

The STIEBER Clutch GFRN-35 F5 F6 NSNBC01 is a self-contained, oil‑lubricated freewheel clutch from Stieber Clutch GmbH designed for overrunning and indexing tasks in drive trains. Built in the GFRN family, this roller‑type unit transmits torque through an external keyway on the outer diameter and uses two bearings from the 160.. series, with the assembly being sealed and bearing‑supported for reliable operation. The outer race is plain to allow components bored to H7 tolerance, enabling precise alignment in the driven design. When shipped disassembled, the unit must be lubricated prior to use, and the housing is closed with F5 and F6 covers to transmit torque and seal the mechanism. GFR and GFRN devices are commonly used as directional clutches in machinery, including winches, where automatic engagement and disengagement are required. The GFRN variant features a defined outer‑diameter keyway to transmit torque while maintaining Stieber’s standard approach to lubrication, bearing support, and compact, maintenance‑friendly design. The NSNBC01 suffix represents the specific order code for this configuration, ensuring you receive the GFRN‑35 size with the F5F6 cover arrangement and the associated service data.
