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.

With a bellows between two hubs, these couplings handle all types of misalignment and are good for precision stepper and encoder motion-control applications.

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.

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.

Each hub includes a set screw, 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.

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.

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

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

Set screws bite into your shaft to hold these couplings in place.

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

Install and remove these shaft couplings without disconnecting the shafts, motors, and other attached components—they’re made in two pieces so you don’t need to slide them onto shaft ends. They’re also useful when you have limited access to the ends of the shafts.

Machine the pilot hole in these couplings to whatever size you need. Often used for shafts that are undersized from wear or oversized from coatings. These couplings are two-piece, so you can remove and reinstall them without moving your shafts.

Tell us the size of each shaft, and we'll machine a custom two-piece coupling to meet your needs.

Access one shaft without disconnecting the other. These rigid couplings have a solid bottom that connects the shafts and two top pieces that clamp the shafts independently.

These U-joints are made of steel or zinc.

These steel U-joints meet MIL-U-20625A Class A and have hardened yoke ears for added strength and durability.

These U-joints are made of steel or plastic.

Stainless steel hubs allow these U-joints to handle harsh environments.

These U-joints handle at least 11,000 in.-lbs. of torque.

These joints are made of steel.

A set of gears transmit rotary motion at angles up to 136°—the widest angle of all our U-joints. They are for hand-powered, low-speed applications.

Stainless steel U-joints are more corrosion resistant than steel U-joints.

Adjust the length of these U-joints between 2 3/4" to 3" to fit your application.

Customize the bore size of these joints to fit your shaft. Each end has a small centered starter hole that makes drilling easy.

These stainless steel shafts are more corrosion resistant than steel models.

Reduce the diameter of your shaft while adding length.

To protect power-transmission components from damage, these couplings will shear or tear in overtorque conditions (approximately 10-20 times the maximum rated torque) to sever connections between shafts.

Adjust your system's torque limit by hand.

Also known as hysteresis clutches, these couplings use magnetic force to brake, control tension, and prevent torque overload. They have a shaft on one end for connecting to other components.

Often used in automated systems, these couplings are both air actuated and remotely adjustable, so you can adjust the torque setting even during operation.

Also known as hysteresis clutches, these couplings use magnetic force to brake, control tension, and prevent torque overload. They have few moving parts, so they last longer than mechanical couplings.

Install cutoff wheels, grinding wheels, and other abrasive discs to the threaded shaft on bench-top motors, grinders, and buffers.

Attach to grinder and buffer shafts to hold buffing wheels with shanks.

Mount to the straight shaft on your grinder or buffer.

Install a sanding sleeve on the threaded shaft of a bench or pedestal grinder using one of these drums.
