Quality control

The quality control of the angular contact ball bearing for ball screw support, the tightening of the outer ring and the prestretching of ball screw is very important. Poor assembly quality will lead to a series of failures, such as large noise, abnormal temperature rise, vibration value increase, etc., seriously affect the positioning accuracy and service life of the machine tool. Therefore, in the design and manufacturing process, quality control should be strengthened to ensure that every step meets the requirements.
