SFNUR1605 Ball Screw

Product Overview

The SFNUR1605 Ball Screw is an internal circulation flange-type ball screw designed for precise linear motion transmission. With a nominal diameter of 16 mm and a lead of 5 mm, it converts rotary motion into accurate linear movement through rolling ball contact.

Compared with conventional lead screws, SFNUR series ball screws offer higher transmission efficiency, lower friction, improved positioning accuracy, and longer service life.

Manufactured from high-quality alloy steel and processed through precision machining and heat treatment, this product delivers excellent rigidity, wear resistance, and operational stability, making it suitable for a wide range of industrial automation applications.

It is ideal for equipment requiring repeatable positioning, high load capacity, and long-term stable operation.
