These shafts have keyways only on the ends, leaving a plain shaft in the center. Use the keyways with machine keys to transmit torque to gears, sprockets, and other keyed components. Use the middle of the shaft with bearings and other round-bore components.

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

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.

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

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

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.

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

Safely connect slightly misaligned shafts near food lines—the spider on these couplings contains metal, so it’ll trigger a metal detector if a piece frays off and contaminates your batch.

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

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

Made with lightweight nylon sleeves, these gear couplings require less energy to move than other high-torque flexible couplings. They compensate for parallel, angular, and axial misalignment.

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.

Install these collars anywhere on a shaft without removing components or having access to the ends of the shaft.

With larger screws than those found on standard clamping collars, these provide a stronger grip on your shaft without using additional screws.
