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.

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.

Often used in electronics manufacturing facilities and other extra-clean environments, these shaft couplings are cleaned and individually bagged to keep out contaminants.

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.

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

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.

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.

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

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

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.

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

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.

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

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.

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.

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.

Pivot the head to access fasteners from an angle.
