What is a stainless steel lead screw?

The raw material for stainless steel lead screws is typically quenched and tempered carbon steel. While alloy steels offer greater reliability, they come at a higher cost. In China, 45# steel subjected to quenching and tempering, or 40Cr, is commonly used as the preferred choice. Some manufacturers also employ stainless steels—such as grades 200, 201, 303, 304, and 316—particularly for fine‑pitch multi‑start lead screws.

How should a ball screw be properly maintained?

Ball screw assemblies must be equipped with protective devices to prevent dust and other contaminants from entering the assembly. If the ball screw assembly is exposed on the exterior of the machine tool, a sealed protective cover must be used; options include helical spring‑steel strip sleeves or pleated sleeves, among others.

Methods for Addressing Lead Screw Noise

Compared with sliding screw assemblies, the driving torque is reduced to one-third. Moreover, because the trapezoidal‑threaded screw and its nut are supported by numerous rolling balls that roll continuously, the system achieves higher motion efficiency. Compared with earlier sliding screw assemblies, the required driving torque is less than one-third, meaning that achieving the same motion performance demands only one-third of the power needed when using a rolling‑element screw assembly. This results in significant energy savings.
