For light duty applications, choose these metric-sized coupling nuts.

Made from Grade 5 steel, these inch-sized coupling nuts are suitable for most applications.

Made from Grade 8 steel, these nuts are about 25% stronger than medium-strength steel coupling nuts. Furnished in inch thread sizes.

Comparable in strength to Grade 9 bolts, these coupling nuts are about 20% stronger than high-strength steel coupling nuts. Available in inch thread sizes.

These metric coupling nuts have good chemical resistance.

More corrosion resistant than 18-8 stainless steel coupling nuts, these metric nuts have excellent resistance to chemicals and salt water.

Brass coupling nuts are corrosion resistant in wet environments and electrically conductive.

Stainless steel coupling nuts have excellent corrosion resistance in most environments.

Known for their strength, steel coupling nuts are available with a corrosion-resistant finish.

Often called sleeve nuts, these thread adapters fasten parts with right-hand threads to parts with left-hand threads.

Increase or decrease metric thread size from one male-threaded part to another. Commonly used to connect two differently sized threaded rods, they have a hex-shaped body, so you can tighten them with a standard wrench.

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

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.

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.

For hard-to-access shafts that are oversized from coatings or undersized from wear, we’ll get you a coupling in the right size that clamps on as two pieces, so you don’t need to move your shafts or installed components.

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.

The thick split spider on these couplings takes on twice as much torque as standard split spiders, while a set screw holds the hubs in place on your shaft. Also known as jaw couplings, use them to connect motors to pumps, mixers, and other high-torque equipment.

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.

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

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

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

Tighten the set screws to fasten these couplings to your shaft. Set screws bite into the shaft to hold the couplings in place.

Also called double-loop couplings, these have a flexible center that reduces vibration and compensates for high parallel and angular shaft misalignment.

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

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.

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

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

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

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.

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

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

These U-joints handle at least 11,000 in.-lbs. of torque.

These joints are made of steel.

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.

Customize the bore size of these joints to fit your shaft. Each end has a small centered starter hole that makes drilling easy.

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

With a strong steel core, a protective plastic case, and bearings, these shafts handle the demands of high-torque applications.

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.

These internally threaded rod ends have an eyelet and a ball that swivels to support angular misalignment. Also known as rod-end bearings.

A PTFE-embedded insert or PTFE liner reduces wear, handles shock loads, and eliminates the need for lubrication.

Connect your grease gun to the fitting to lubricate. Internal threads mate with rod end bolts, threaded rods, and other components with male threads.

These internally threaded rod ends have an oil-embedded bronze insert that slowly releases lubricant over time. Connect your grease gun to the fitting to relubricate.

An oil-embedded bronze insert slowly releases lubricant throughout the life of these internally threaded rod ends.

Made of cadmium-plated steel, these internally threaded rod ends generally handle higher loads than stainless steel, aluminum, and nylon rod ends.

With at least 55° of ball swivel, these rod ends accommodate greater misalignment than any other internally threaded rod end we offer.

Made of cadmium-plated steel, these externally threaded rod ends generally handle higher loads than stainless steel, aluminum, and nylon rod ends.
