THK Ball Screw Peripheral Lock Nut

The Lock Nut for Ball Screws is designed to securely fasten the screw shaft and bearing with high accuracy.

A hexagonal socket-head set screw and set piece are provided to prevent loosening, ensuring firm and reliable fastening during operation. This contributes to stable shaft positioning and long-term reliability in ball screw assemblies.

The Model RN ball screw lock nut is used for fixing the angular bearings that set into ball screws.
Available in sizes M4 to M40. Screw pitches must be narrow.
