Each hub includes a set screw (unless noted), which bites into your shaft to hold the coupling in place.

Designed to grip evenly around your shaft, these couplings provide more holding power than set screw couplings without marring the shaft.

Designed to grip evenly around your shaft, these couplings provide more holding power than set screw couplings without marring the shaft.

A strip of flexible spring steel wraps around the teeth of both hubs to absorb sharp, momentary load increases that can come from motor startups, emergency braking, or sudden impact with hard objects.

Tighten the set screws to fasten these couplings to your shaft. Set screws bite into the shaft to hold the couplings in place.

Also called double-loop couplings, these have a flexible center that reduces vibration and compensates for high parallel and angular shaft misalignment.

Designed to grip evenly around your shaft, these couplings provide more holding power than set screw couplings without marring the shaft.

An acetal plastic spacer at the center of these couplings insulates bearings, encoders, and other shaft components from stray electric current. Use them with servomotors, which sometimes generate current that travels down the shaft and can damage circuit boards, interfere with readings, and cause wear on bearing raceways.

Specially designed ridges allow these bellows couplings to compensate for more misalignment than other precision couplings—useful for low-torque, high-precision applications such as instrumentation and motion control.

Use these gear-shaped couplings for high-speed and high-torque applications.

With a rigid gear design, these steel couplings transmit more torque than other couplings of the same size.

Magnetic force transfers torque from one half of these couplings to the other; there’s no contact between the parts, so they won’t wear. Couplings compensate for angular and parallel misalignment.

Lengthen and shorten these telescoping U-joints to fit your application. They’re a good choice when you need accurate and repeatable motion because they have zero backlash (no play), so there’s no motion lost when the shafts change direction.

Connect and transfer torque between two shafts that are either parallel to each other or are misaligned at an angle.

The gears on these U-joints transmit rotary motion between shafts that are misaligned at angles up to 136°, the widest angle of all our U-joints.

A good choice when you need accurate and repeatable motion, these U-joints have zero backlash (no play), so there’s no motion lost when your shafts change direction.

Choose these U-joints for applications that run continuously in wet environments.

Use these U-joints in wet environments to connect and transfer torque between two shafts.

Ideal for wet environments, these U-Joints are stainless steel, so they have good corrosion resistance while also balancing strength. They have a heat- and water-resistant silicone cover (also known as a boot or bellows) to keep lubricant in and contaminants out.

With a maximum torque of at least 11,600 in.-lbs., these U-joints handle more torque than any other U-joint in our offering.
