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

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.

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.

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

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

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

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.

One end has a finished bore size; the other can be machined to any size—great for connecting to uncommon shaft sizes and shafts that are undersized from wear or oversized from coatings.

When other one-piece clamping couplings won’t fit your shafts, we’ll machine a shaft coupling with the exact shaft diameters you need.

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.

When your shafts are not close enough to use standard couplings, these have the length to bridge the gap.

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 joints are made of steel.

These joints are made of steel.

These U-joints are made of steel or zinc.

Keep shafts moving in sync with these U-joints—a flexible spring at the center stabilizes input and output speed and reduces vibration.

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.

These U-joints are made of steel or plastic.

Joints have a fixed 2 1/2" overall length.

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

Increase the diameter of your shaft while also making it longer.

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.
