Recirculating ball screw -
The ball screw drive by THOMSON is a combination of ball screw and ball nuts with circulating ball bearings that transforms either circulating motion into liner motion or the other way around. The uniform design of each screw ball had made all the screw and nuts match easily together. Rolling elements reduce the friction making the product more efficient higher than 90%. It also has a number of ball bearings that accept mostly all the force being transferred to them resulting in a low relative load per ball.
