Plastic Two-Piece Shaft Collars

Lightweight alternatives to metal two-piece collars for weight-sensitive applications. Attach these collars anywhere along a shaft when other components are already installed or you can't access the ends. They clamp firmly and evenly without marring the shaft, so you can reposition or remove them later.

Acetal—Resist swelling when exposed to moisture.

Shaft Collars

Slide these collars from one end of your shaft and tighten the clamping screw. They grip firmly and 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.

Shaft Collars with Lever

Ideal for frequent setup changes in tight spaces, these collars tighten with a lever instead of a screwdriver. Slide them from one end of your shaft and turn the lever like a ratchet to secure. To reposition or remove collars later, use the lever to loosen the screw and release the hold.

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.

Black Anodized Aluminum—One-third the weight of steel and more corrosion resistant than unfinished aluminum.

Two-Piece Shaft Collars with Lever

Skip the screwdriver—tighten these collars by turning the lever like a ratchet instead. They're ideal for packing, printing, label-feeding, and other equipment requiring frequent setup changes in tight spaces. Attach them anywhere along your shaft, which helps when other components are already installed or you can't access the ends. To reposition or remove collars later, use the lever to loosen the screw and release the hold.

Two-Piece Shaft Collars

For Round Shafts

Attach these collars anywhere along your shaft, which helps when other components are already installed or you can't access the end. They clamp firmly and evenly without marring the shaft, so you can reposition or remove collars 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.

316 Stainless Steel—More corrosion resistant than 303 stainless steel collars. These collars withstand salt water and harsh chemicals, such as bleach, chlorine, and phosphoric acid.

Aluminum—One-third the weight of steel and corrosion resistant.
