The Stieber GFR Ø60 mm is a robust and modular roller-type freewheel designed for high-speed applications with secure torque transmission. It accommodates a shaft diameter of Ø60 mm and supports 650 rpm on the inner race and up to 2450 rpm on the outer race. With a maximum torque of 3,500 Nm, it ensures reliable operation in compact, demanding systems.

As part of the Stieber modular system, this unit uses two 160-series ball bearings and requires external oil lubrication. The plain outer race fits H7 tolerance bores, and torque is transferred via bolts through the cover plate. Typically used with F-series covers that provide sealing and lubrication. Two paper seals are supplied for correct installation.
