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.

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.

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

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.

Designed for use in food-processing applications, where a fraying spider could contaminate a batch, these couplings have a metal-detectable 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.

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

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.

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

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.

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

Made of stainless steel, these U-joints offer excellent corrosion resistance.

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

These joints are made of steel.

These pin-and-block style U-joints work at lower speeds but transmit greater torque than needle-bearing joints.

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

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