Product Overview
The SFNUR3210 Ball Screw is an internal circulation flange-type ball screw designed for high-load and medium-to-high-speed linear transmission applications. Featuring a nominal diameter of 32 mm and a lead of 10 mm, it converts rotary motion into precise linear movement with excellent efficiency and positioning accuracy.
Compared with conventional lead screws, the SFNUR series significantly reduces friction through rolling ball contact, providing smoother operation, lower energy consumption, and extended service life.
Manufactured from premium alloy steel and processed with precision machining and heat treatment technology, SFNUR3210 delivers reliable performance under continuous industrial operating conditions.
It is widely used in automation equipment, CNC systems, industrial machinery, and applications requiring stable, high-load motion control.
