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.

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.

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.

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

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

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

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.

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.

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.

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.

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

Also known as hysteresis clutches, these couplings use magnetic force to brake, control tension, and prevent torque overload. They have few moving parts, so they last longer than mechanical couplings.

Install cutoff wheels, grinding wheels, and other abrasive discs to the threaded shaft on bench-top motors, grinders, and buffers.

Attach to grinder and buffer shafts to hold buffing wheels with shanks.

Mount to the straight shaft on your grinder or buffer.

Mount a sanding sleeve to the straight shaft of a bench or pedestal grinder using one of these drums.

A toothed slot lets these bushings contract for insertion into the bore of your sprocket or pulley and then expand for a snug fit.

18-8 stainless steel spacers have good corrosion resistance.

Made from brass, these inserts are nonmagnetic, mildly corrosion resistant, and electrically conductive.

Pivot the head to access fasteners from an angle.

Also known as rod‐end bearings, ball joint rod ends have an eyelet and a ball that swivels to support angular misalignment.

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

An oil-embedded bronze insert slowly releases lubricant to the rod end. Connect your grease gun to the fitting to relubricate.

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

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.

Similar to turnbuckles, these rods have right-hand threads on one end and left-hand threads on the other so you can make a linkage that adjusts for tension.
