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 can take on twice as much torque as standard spiders, extending the life of bearings, seals, and motors.

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

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.

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.

Designed for use in food-processing applications, where a fraying spider could contaminate a batch, these couplings have a metal-detectable rubber spider. Small pieces of metal inside the rubber will set off a metal detector, alerting you to the problem.

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

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 splined shafts to keyed shafts. These couplings are commonly used to connect hydraulic pumps, compressors, and other heavy duty equipment, which often have splined shafts, to electric motors and other components that often have keyed shafts.
