BSQ BF Type Support Unit

The BF Type Support Unit is a block-type supported-side unit designed to support the non-driven end of a ball screw. It uses a deep groove ball bearing, allowing smooth rotation while accommodating radial loads. This structure provides stable shaft support without axial constraint, enabling thermal expansion of the ball screw. The BF type is commonly used in combination with BK or FK fixed-side units in standard ball screw assemblies.
