Purpose:

Ball Screw/Lead Screw is widely used for all kinds of industrial equipment and precise instrument, especially for CNC machine. It is the heart to the high-speed machine.

Ball Screw is used for transfer the linear motion to rotary motion or transfer the rotary motion to linear motion

Feature:

1.         High precision

2.         Dustproof by brusher attachment both before and behind screw cap

3.         Protect oil from spilling by attaching O-shape color to the brusher near flange

4.         Durability
