Heavy load 32mm diameter spindle ball lead screw bearing SFU3210 with double nut DFU3210

Ball screw assembly is consisted of screw, nut and ball. The function is to turn the rotary motion into liner motion, which is a further extension and development of ball screw. The significance of this development is to move into a rolling bearing from sliding action; With little friction, ball screws are widely used in various industrial equipment and precision instruments. Especially in recent years, it is widely used in CNC machine tools. ball screw is made by grinding and whirling, or rolled, and it has two kinds of ball screw, accuracy from C5 to C7.

We are able to end machining, if you need, Please let us know before order, and please provide a detailed end machined drawing, if not, we will not end machined the ball screw. Any length of the ball screw, we can satisfy to you.

A ball screw is a mechanical linear actuator that translates rotational motion to linear motion with little friction. A threaded shaft provides a helical raceway for ball bearingswhich act as a precision screw. As well as being able to apply or withstand high thrust loads, they can do so with minimum internal friction. They are made to close tolerances and are therefore suitable for use in situations in which high precision is necessary. The ball assembly acts as the nut while the threaded shaft is the screw. In contrast to conventional leadscrews, ballscrews tend to be rather bulky, due to the need to have a mechanism to re-circulate the balls.

 
Advantages:
Low friction in ball screws yields high mechanical efficiency compared to alternatives. A typical ball screw may be 90 percent efficient, versus 20 to 25 percent efficiency of an Acme lead screw of equal size. Lack of sliding friction between the nut and screw lends itself to extended lifespan of the screw assembly (especially in no-backlash systems), reducing downtime for maintenance and parts replacement, while also decreasing demand for lubrication. This, combined with their overall performance benefits and reduced power requirements, may offset the initial costs of using ball screws.
