Floating ball screw support BF 15 - Hiwin

BF 15 fixed support or floating support for ball screw with nominal shaft diameter of 20mm, includes bearing rigid ball screw.


For proper operation, ball screws need support points with bearings at their ends; because the screws support and generate axial and radial forces, they will need a fixed support at one end and a support or floating support at the other end.

BF type floating supports allow slight axial movement, accommodating thermal expansion and contraction of the ball screw. They are generally used at the opposite end of the ball screw to prevent binding and ensure smooth operation. These types of supports are assembled on the spindle on the opposite side of the motor.

BF type supports are suitable for providing stability and accuracy in linear motion applications, they provide strong support for the spindles, giving longer spindle life and better spindle performance by reducing spindle wear. Their rigid design minimizes spindle deflection, ensuring alignment and accuracy of motion.


The spindle height of the BF floating support bearing matches that of the BK fixed support bearing. The spindle end machining suitable for BK fixed supports is type E10-xx.
