Ruland Shaft Collars

One-Piece Clamp Style Shaft Collars

The one-piece clamp style shaft collar wraps around the shaft for even distribution of clamping forces. This results in a tight fit and greater holding power, without the shaft damage caused by set screws. Ruland uses carefully selected materials and proprietary processes to ensure that the clamping gap remains open for simpler and more precise adjustment, installation and fit.  


• Even distribution of clamping force
• Does not mar the shaft
• Single point faced
