Tips: The role of ball screw bearing
The two ends of the ball screw can be installed on a fixed seat and a support seat after processing. The support seat is a unity of the two methods. The fixing seat and the supporting seat are installed on both ends of the screw to fix the screw, and the mold uses ball screw bearings. Rotating.
