Compact one-way clutch from Stieber with Ø120 mm shaft, imax 250 rpm, 12 bolt holes, and max torque of 31,250 Nm. Ideal for backstop and indexing in industrial systems.

The Stieber AL 120 is a modular roller-type freewheel engineered for overrunning and backstop applications in demanding industrial setups. With a shaft interface diameter of 120 mm and integration via H7-tolerance fits, the unit provides precise coupling and effective torque transfer through a bolted outer cover.

Constructed with hardened steel races and a brass cage, the AL 120 includes two 160-series bearings for radial and axial load support—ensuring stable operation when axially unladen. It is oil-lubricated and delivered with paper seals to facilitate proper sealing during installation. Torque is transmitted through the plain outer race, allowing a compact, bolt-through cover plate interface.

As part of Stieber’s modular AL range, this freewheel can be paired with standard torque-transmitting covers or customized for OEM-specific applications. Ideal for use in heavy-duty conveyors, belt drives, or gear assemblies requiring high reliability and low backlash performance.
