High Precision External Circulation Screw Shaft

High Precision External Circulation Screw Shaft | Large Diameter Large Lead Ball Screw Shaft 1. Product Brief Introduction High Precision External Circulation Screw Shaft adopts an external circulation tube structure. The circulating tube guides steel balls through the inner hole and sends them back to the loaded ball track to form continuous cyclic movement. According to whether the circulation tube assembly protrudes from the nut outer diameter, external circulation ball screws are divided into built-in wrapped type and outward protruding type. This screw shaft supports abundant combinations of nominal diameter and lead, and is specially designed for large-diameter and large-lead application scenarios with stable ball circulation and smooth transmission performance. 2. Core Product Performance Advantages Mature External Circulation Tube Structure: Steel balls circulate through independent external tubes, with smooth ball return path, low friction loss and stable long-term operation…
