Product Description

Product Description

Totem Precision Ground Lead Screws (C3/C5/C7 Grade)  for CNC Machining Centers

Ball screws are electromechanical actuators that convert rotary motion into precise linear displacement through recirculating ball bearings between the screw shaft and nut. The rolling friction mechanism achieves >90% mechanical efficiency, significantly outperforming conventional lead screws.
