Ball screw end supports bearing mounts BK bearing blocks

Huayu Ball Screw Support Units provide all parts required for mounting Ball Screws as a set to machines: support units for light load & small equipment as well as ball screw support units for heavy load- and machine tool applications.

BK/BF end supports are sometimes referred to as the "pillow block" style. Mounting holes are provided to secure these bolts to the base on which the ball screw will run.
BK "fixed" end supports consist of two angular contact bearings that provide axial and rotational support for the ball screw.
A BF "simple/floating" support has just a standard ball bearing that provides rotational support at the end of the ball screw opposite where the drive occurs (usually the motor or pulley).
Our standard ball screws come machined to work with these brackets without modification.
