Axial bearing unit BF series

metal

NEFF’s BF loose bearing units provide precise and reliable support for the loose end of ball screws. When combined with a BK fixed bearing unit, they form an optimally matched bearing solution for ball screws and ensure safe, long-lasting, and trouble-free operation.

The BF floating bearing unit is specifically designed to support the non-driven side of a ball screw. It allows for axial movement of the screw, thereby promoting low-stress operation under various operating conditions. Thanks to its compact design and easy integration, it is ideally suited for numerous applications in industrial linear technology.
