The ball screw pair has the characteristics of high precision, reversibility and high efficiency, which is the further extension and development of the ladder screw, and the important significance of this development is to change the sliding action of the ladder screw into a rolling action. Because of its small friction resistance, ball screw bearings are widely used in various industrial equipment and precision instruments.

The ball screw pair is based on the accumulated product technology over the years, from materials, thermal external treatment, manufacturing, inspection to shipment, are managed by a rigorous quality assurance system, so it has high reliability.
(1) Double push one free mode: one end of the screw is fixed and the end is free. Fixed-end bearings bear both axial and radial forces. This Rabha support is used for short lead screws with small travel.
(2) Double push and support mode: one end of the lead screw is fixed and the other end is supported. Fixed end bearings bear both axial and radial forces. Support end bearings only bear radial forces? Moreover, it can make a small amount of axial float to avoid or reduce the bending of the lead screw due to its own weight. At the same time, the lead screw thermal deformation can be freely extended to one end.
