Use these gear-shaped couplings for high-speed and high-torque applications. A rubber center allows flexing so couplings can take on multiple types of misalignment while damping vibration and shock. With no metal-to-metal contact, there’s no need for lubrication. Fasten to your shafts by tightening the set screws, which bite into the shaft to hold it.

A complete coupling consists of two hubs and one center (each component sold separately).

Hubs have a keyway, except hubs for 1/4" and 3/8" shaft dia. do not have a keyway.

Made with lightweight nylon sleeves, these gear couplings require less energy to move than other high-torque flexible couplings. They compensate for parallel, angular, and axial misalignment. Fasten to your shafts by tightening the set screws, which bite into the shaft to hold it.

A complete coupling consists of two hubs and one sleeve (each component sold separately).

One end has a finished bore size; the other can be machined to any size—great for connecting to uncommon shaft sizes and shafts that are undersized from wear or oversized from coatings. Slide these couplings onto your shafts and tighten the clamping screws for a secure hold that won’t damage the shafts. All of these couplings are rigid and must be used on aligned shafts. They prevent movement between the shafts, so they can handle high-torque applications.

Couplings for keyed shafts have keyways that firmly grip the shaft’s key to eliminate slipping. They handle higher torque than couplings for round shafts.

Steel couplings are a good option in dry environments.

303 stainless steel couplings resist corrosion caused by water. They're good for wet and damp environments but will corrode when exposed to salt water and other chloride solutions.

Slide these couplings onto the end of your shaft and tighten the set screws to secure. Set screws bite into the shaft to hold the coupling in place. Good for high-torque applications, rigid couplings connect two shafts that are aligned, allowing for no relative movement between the shafts.

Black-oxide steel couplings have some corrosion resistance. Stainless steel couplings have excellent corrosion resistance.

Couplings with four set screws hold better than couplings with two set screws.

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.

Couplings for keyed shafts have keyways that are cut to standard ANSI dimensions, so they fit snugly on ANSI keyed shafts to eliminate slipping during starts and stops.

Steel couplings are stronger and handle higher torque loads than aluminum and stainless steel couplings.

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