High Precision Ball Screws

Function of ball screw:
Ball Screw is made of screw and ball nut. It's function is to turn the rotary
Motion into linear motion., which is a future extension and development of ball
Screw. The significance of the development is to move into a rolling bearing
From sliding action. With little frication, Ball Screw are widely used into
Various industrial equipment and precision instruments such as engraving machines, high speed machinery (CNC Machinery), window machines, semi-conductor equipment, and others.

Application:
1. Machine tools
2. Industrial machinery Printing, paper-processing, automatic machines, textiles, etc.
3. Electronic machinery Robot, measuring instruments, medical equipment, X-Y table, factory automation equipment, etc.
4. Transport machinery Material handling equipment, etc.
5. Aircraft applications: Aircraft flaps, actuators, airport loading equipment, etc.
Condition: Brand new, unused item. The ball screw is MADE IN Taiwan, So the hardness of the ball screw is more uniform, better quality.
