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

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

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

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.

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

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.

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.

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

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.

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.
