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

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

Able to handle high twisting forces as well as misalignment, these couplings are good for high-performance servomotor applications.

Connect shafts and ball screws to high-speed servomotors and stepper motors—these shaft couplings handle four times more speed than standard servomotor couplings.

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.

The thick split spider on these couplings takes on twice as much torque as standard split spiders, while a set screw holds the hubs in place on your shaft. Also known as jaw couplings, use them to connect motors to pumps, mixers, and other high-torque equipment.

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.

Customize the bore of these flexible couplings to align uncommon shaft sizes as well as shafts that have become undersized from wear or oversized from coatings.

Also known as Schmidt couplings, these handle higher angular misalignment than other three-piece couplings. Good for applications with varying shaft misalignment, they're commonly used with conveyor rollers and roller feeds in printing and packaging machines.

With a rugged roller-chain design, these couplings provide excellent torque and angular misalignment capacities.

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

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.

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

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.

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

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

Made to meet strict military standards for material and construction, these stainless steel U-joints also balance strength with good corrosion resistance. Customize their bores until they fit your 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.

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.

To keep your shafts moving in sync, the flexible spring on these joints makes the output shaft move at the same rate as the input shaft.
