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.

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.

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

Use these gear-shaped couplings for high-speed and high-torque applications.

When one of your shafts is undersized from wear, oversized from coatings, or uncommonly sized, machine one end of these couplings to fit. They clamp around your shafts for a secure hold that won’t cause damage.

When you need a strong hold and even grip on shafts that are oversized due to finishes, undersized from wear, or uncommonly sized, we’ll make a coupling for you that fits just right. These couplings clamp around your shafts to prevent marring them.

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.

Support the weight of a motor and transfer torque to another shaft at the same time with these couplings.

Extend the life of your rigid shaft couplings by blocking out dirt, water, lubricants, and other contaminants. These two-piece covers twist together to form a shell around the coupling.

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

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

These U-joints are made of steel or plastic.

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

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

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.

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

Reduce the diameter of your shaft while adding length.

Protect shafts, motors, and gear boxes from damage that’s caused by torque overload from machine jams and emergency stops.

Adjust your system's torque limit by hand.

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

Use these with an overload sensor in an automated system to instantly disconnect power and prevent damage. Couplings also accelerate loads from zero to full speed in less than three milliseconds when the power is turned on.
