Purpose of Ball Screw Pretension 1. Reduce the bending of ball crew due the weight 2. Compensate the thermal expansion of ball screw 3. Increasing the rigidity of ball screw What are the causes for Ball Screw failure? ▎Here for more info: https://www.tpi.tw/msg/msg93.html

During the process of tool machine, the instant large axial impact damages the bearing, resulting in isometric indentation around the bearing raceway, and then generates noise during operation.

If the minimum load requirements are not met, sliding can occur and generates excessive heat and noise. In addition, loose fit between bearing and rotor can also have a detrimental effect on bearing performance because of sliding. Adequate load and correct fit selection are essential in preventing skidding. ▎Click here for Effective Countermeasures: https://www.tpi.tw/m...
