About Shaft Couplings

Quick-Disconnect (QD) Weld-On Bushing-Bore Hubs

These hubs are compatible with Quick-Disconnect (QD) Bushings.

Taper-Lock Weld-On Bushing-Bore Hubs

Use these hubs with our Taper-Lock Bushings.

Split-Tapered Weld-On Bushing-Bore Hubs

Taper-Lock Bushings

Mount these hubless bushings flush into your sprocket or pulley for a slim profile with no protruding screws.

Flexible Shaft Couplings for Continuous Motion

Vibration-Damping Flexible Shaft Couplings

A flexible tire on these couplings safeguards components on your shafts by reducing vibration and shock.

High-Speed Vibration-Damping Flexible Shaft Couplings

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

Noncontact Magnetic Shaft Couplings

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.

Ultra-High-Torque Flexible Shaft Couplings

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

Lightweight Flexible Shaft Couplings

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.

High-Torque Flexible Shaft Couplings

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

Flexible Shaft Couplings for Forward/Reverse Motion

Clamping High-Parallel-Misalignment
Flexible Shaft Couplings

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

Set Screw High-Parallel-Misalignment
Flexible Shaft Couplings

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

Metal-Detectable Flexible Shaft Couplings

Safely connect slightly misaligned shafts near food lines—the spider on these couplings contains metal, so it’ll trigger a metal detector if a piece frays off and contaminates your batch.

Clamping Flexible Shaft Couplings

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

Machinable-Bore Flexible Shaft Couplings

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.

Set Screw Flexible Shaft Couplings

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

High-Angular-Misalignment Flexible Shaft Couplings

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.

Shock-Absorbing Flexible Shaft Couplings

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.

High-Torque Set Screw Flexible Shaft Couplings

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.

Set Screw Vibration-Damping
Precision Flexible Shaft Couplings

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

Clamping Vibration-Damping
Precision Flexible Shaft Couplings

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

Splined Flexible Shaft Couplings

For use with splined shafts, which are commonly found in gearboxes and pumps, these couplings are capable of transmitting more torque than couplings for round and keyed shafts.

Splined-to-Keyed Flexible Shaft Couplings

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.
