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.

Aluminum couplings are lightweight, making them useful in precision motion control and servomotor applications.

303 stainless steel couplings resist corrosion, so they’re often used in wet conditions, such as with mixers and pumps.

316 stainless steel couplings are more corrosion resistant than 303 stainless steel couplings. They’re good for marine environments and washdown applications involving chemicals such as chlorides.
