SFY Ball Screw

SFY High-Lead Ball Screw

The SFY Series Ball Screw is a high-lead ball screw designed for high-speed linear motion, CNC equipment, factory automation and other applications where rapid travel and smooth operation are important.

The SFY design combines a large screw lead with an internal end-cap ball recirculation system. This circulation architecture is intended to support high-speed operation while maintaining smooth ball movement within the nut.

Yongrun's SFY range also includes high-lead models such as SFY02040, SFY2020, SFY4040 and SFY5050, providing different diameter-to-lead combinations for different motion requirements.
