Oversized Two-Piece Shaft Collars


For Round Shafts	For Keyed Shafts

Wider and thicker with larger clamping screws, these deliver a more powerful hold than standard two-piece collars. Attach them anywhere along a shaft when other components are already installed or you can't access the ends. They grip evenly without marring the shaft, so you can reposition or remove them later.

Black-Oxide Carbon Steel—Dark and matted for a finished look, but with minimal corrosion resistance. Best for dry environments.

303 Stainless Steel—Withstand moisture and mild cleaning solutions, such as acetone and ammonia. These are easier to machine than other stainless steel collars.

Tight-Hold Shaft Collars

Our strongest shaft collars withstand up to three times the thrust load (force parallel to the shaft) of standard collars. Slide them from one end of your shaft and turn the clamping screws. As the collar tightens, an embedded sleeve spreads force evenly for a firm grip that won't mar the shaft.

Black-Oxide Carbon Steel—Dark and matted for a finished look, but with minimal corrosion resistance. Best for dry environments.
