F&T is ball screw bearings supplier and ball screw support bearings factory.
Ball screw bearings are designed to support the axial load and radial load of the ball screw shaft. They are typically mounted on the ends of the ball screw shaft and are used to reduce friction and ensure smooth operation of the ball screw assembly.
Ball screw support bearings, on the other hand, are used to support the ball screw shaft at various points along its length. They are typically mounted on a separate support structure and are used to prevent the ball screw shaft from bending or deflecting under load.
Both types of bearings are critical components in ball screw assemblies.

F&T ball screw support bearings FAQ
1. What are the differences between fixed-side and floating-side ball screw support bearings?
Answer: Fixed-side bearings are designed to provide rigid support on one end of the ball screw, while floating-side bearings allow for axial movement to compensate for thermal expansion or slight misalignments, providing flexibility in the ball screw assembly.
2. Can ball screw support bearings be used in vertical applications?
Answer: Yes, ball screw support bearings are suitable for vertical applications, provided that the bearing arrangement and preload are selected to accommodate the axial forces and ensure stable operation under vertical loading conditions.
