Ruland Shaft Collars

One-Piece Clamp Style Shaft Collars - Threaded Bearing Locknut

Bearing locknuts are essentially a one-piece threaded clamp collar which provides axial holding power superior to any smooth bore collar, while offering easier installation and adjustment than solid ring locking devices. A diverse list of thread diameters and pitches, including locknut threads, are offered. Ruland threaded shaft collars are double tapped to insure precise and burr-free threads.


• Greater axial holding power
• Does not mar the shaft
• Acme, left-hand and metric threads available
• Single point faced
• Balanced styles available for bearing locknuts
