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.

When your shafts are not close enough to use standard couplings, these have the length to bridge the gap.

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

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.

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

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

Specially designed ridges allow these bellows couplings to compensate for more misalignment than other precision couplings—useful for low-torque, high-precision applications such as instrumentation and motion control.

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

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

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

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.

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.

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

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

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.

Often used in automated systems, these couplings are air actuated so you can adjust the torque during operation.

Also known as hysteresis clutches, these couplings use magnetic force to brake, control tension, and prevent torque overload. They have a shaft on one end for connecting to other components.

Adjust your system's torque limit by hand.

Also known as electric hysteresis brakes, these couplings use magnetic force to create drag to slow or stop the motion of your drive system.

Also known as swing bolts and eyebolts, these internally threaded rod end bolts have no moving parts. They're designed to make pivoting or hinge movements in applications that don't need to compensate for misalignment.

These alloy steel rod end bolts have the highest tensile strength of any fully threaded rod end bolt we offer.

These steel rod ends are machined to SAE standards.

Thread or weld the unfinished shank of these rod ends to meet your specific linkage needs.

Make quick adjustments to these rod ends by inserting and releasing the clevis pins without the need to bend them into place.

Designed for use with right-hand, internally threaded rod ends, these rods have right-hand threads on both ends. Use them for remote valve operators, throttle controllers, shifting mechanisms, and virtually any push/pull assembly.

Made of stainless steel, these ball joint linkages offer more corrosion resistance than steel ball joint linkages.

Able to stand up to frequent use, these linkages offer excellent wear resistance. They consist of ball joint rod ends with a ball stud attached to simplify mounting.

A slippery PTFE liner reduces wear and eliminates the need for lubrication.

An oil-embedded bronze insert slowly releases lubricant throughout the life of the joint.

These internally threaded linkages have an oil-embedded bronze insert that slowly releases lubricant throughout the life of the joint.

Along with excellent wear resistance, these linkages have a grease fitting for easy lubrication. An internally threaded rod end connects to threaded rods, studs, and other parts with male threads.
