About Shaft Collars
Shaft collars are useful for holding and positioning components on a shaft. They can also serve as mechanical stops and stroke limiters.

Hex Shaft Collars
To install, slide these one-piece collars onto the end of your shaft. They clamp evenly around the shaft to create a strong, mar-free hold. Tighten the clamping screw to secure.
Black-oxide steel collars have some corrosion resistance. 303 stainless steel collars have excellent corrosion resistance.

Hex Two-Piece Shaft Collars
Install these collars anywhere on a shaft without removing components or having access to the ends of the shaft. Collars clamp evenly around the shaft to create a strong, mar-free hold. Tighten the clamping screws to secure.
Black-oxide steel collars have some corrosion resistance. 303 stainless steel collars have excellent corrosion resistance.

Two-Piece Shaft Couplings
Install and remove these shaft couplings without disconnecting the shafts, motors, and other attached components—they’re made in two pieces so you don’t need to slide them onto shaft ends. They’re also useful when you have limited access to the ends of the shafts. These couplings clamp onto the shafts, creating a secure hold that won’t mar them. Good for high-torque applications, they have a rigid construction. However, their rigidity means these couplings can only connect shafts that are well aligned.
Black-oxide carbon steel couplings have some corrosion resistance but should be used in dry environments.
