BK20/BF20 Ball Screw Support

BK20/BF20 Ball Screw Support

Product descriptions

The BK20/BF20 support set provides the essential "Fixed-Floated" mounting architecture required for heavy-duty 25mm ball screw systems. Manufactured from precision-machined carbon steel and finished with a protective black oxide coating, these units are engineered to maintain structural integrity under extreme industrial loads.
 

• The Fixed End (BK20): Motor-Side Anchor

Positioned at the drive end of the axis, the BK20 serves as the primary structural anchor. It houses a matched pair of preloaded Angular Contact Bearings designed to withstand the intense bi-directional thrust loads generated by high-torque servo motors. Secured by a precision-ground M20 lock nut, this assembly eliminates axial play and "lost motion," ensuring instantaneous response during direction reversals.

• The Floating End (BF20): Thermal Expansion Support

Positioned at the distal end, the BF20 houses a high-quality radial bearing engineered for axial freedom. This "floating" design allows the 25mm shaft to expand and contract linearly as it generates frictional heat during high-speed operation. By accommodating this thermal growth, the BF20 prevents shaft buckling and bowing, preserving positional accuracy and significantly extending the service life of your linear rails.
