First, analyze the causes:

① Poor lubrication or impurities inside the nut;

② Damage to the ball, internal raceway of the nut, or the screw raceway;

③ Improper ball screw installation;

④ Excessive concentricity or circular runout of the ball screw, or screw shaft bending;

In general, manufacturers process ball screw pairs according to user requirements. Therefore, when placing an order, users often need to attach ball screw processing drawings, which can better ensure the performance of the ball screw mechanism.
