The Stieber AL 150 is a self-contained roller-type one-way freewheel, designed for reliable overrunning and backstop functionality in demanding industrial applications. With an outer diameter of 150 mm and an inner race prepared for H7 shaft tolerance, it ensures precise alignment and secure integration into surrounding components.

The unit features a robust steel construction with a brass cage, and includes two 160-series bearings for support of radial and axial loads—note that these must remain free from axial preload to maintain proper function. The design is oil-lubricated and fully sealed, making it well-suited for harsh environments.

Torque is transmitted through the plain outer race, typically by bolting a cover plate. For applications requiring external keying, the ALP version includes a keyway on the outer diameter. Both types are often used with standardized covers for torque transmission and sealing.

Ideal for use in backstopping and overrunning applications in conveyors, hoists, winders, and heavy machinery where precise, durable torque control is critical.
