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.

These couplings have the gripping strength to handle higher torque than most other couplings.

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.

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.

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

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.

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

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.

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.

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.

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

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.

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.

Made of stainless steel, these U-joints offer excellent corrosion resistance. They also meet MIL-U-20625A Class A.

These joints are made of steel.

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 joints are made of steel.

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.

Made of steel, these shafts are stronger than stainless steel flexible shafts.

Reduce the diameter of your shaft while adding length.
