A strip of flexible spring steel wraps around the teeth of both hubs to absorb sharp, momentary load increases that can come from motor startups, emergency braking, or sudden impact with hard objects.

High-Angular-Misalignment Flexible Shaft Couplings

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.

Metal-Detectable Flexible Shaft Couplings

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.

High-Speed Vibration-Damping
Flexible Shaft Couplings

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

High-Torque Flexible Shaft Couplings

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

Ultra-High-Torque Flexible Shaft Couplings

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

Lightweight Flexible Shaft Couplings

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.

Noncontact Magnetic Shaft Couplings

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.

Rigid Shaft Couplings

Clamping Shaft Couplings

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

Machinable-Bore Clamping Shaft Couplings

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.

High-Grip Clamping Shaft Couplings

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

Made-to-Order Clamping Shaft Couplings

When other one-piece clamping couplings won’t fit your shafts, we’ll machine a shaft coupling with the exact shaft diameters you need.

Set Screw Shaft Couplings

Set screws bite into your shaft to hold these couplings in place.

Two-Piece Shaft Couplings

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.

High-Grip Two-Piece Shaft Couplings

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

Made-to-Order Two-Piece Shaft Couplings

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

Two-Piece Shaft Coupling Bridges

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

Three-Piece Shaft Couplings

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.

Keyless Locking Shaft Couplings for Overhung Loads

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

Single U-Joints

Easy-Install Single U-Joints

These U-joints are made of steel or plastic.

High-Torque Easy-Install Single U-Joints

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

Corrosion-Resistant Sealed Easy-Install Single U-Joints

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

Sealed Easy-Install Single U-Joints

These joints are made of steel.

Sanitary Sealed Easy-Install Single U-Joints

Connect misaligned shafts in sanitary environments such as food, cosmetic, and pharmaceutical plants.

Shaft Adapters

Step-Up Shaft Adapters

Increase the diameter of your shaft while also making it longer.

Step-Down Shaft Adapters

Reduce the diameter of your shaft while adding length.

Machinable Shaft Ends

One side is unfinished for milling custom pulleys, threaded hubs, sprockets, collars, knobs, sensor targets, or just about anything imaginable; the other side is a one-piece clamping coupling for mounting whatever you’ve created to your shaft.

Torque-Limiting Shaft Couplings

Torque-Limiting Flexible Shaft Couplings with Alarm

If they exceed maximum torque, these couplings disengage, sound an alarm, and then automatically re-engage once the overtorque condition is eliminated.

Torque-Limiting Flexible Shaft Couplings

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

Torque-Limiting Shaft Couplings

Adjust your system's torque limit by hand.

Air-Powered Torque-Limiting Shaft Couplings

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

Torque-Limiting Shaft-to-Gear Couplings

Adjust your system's torque limit by hand.

Air-Powered Torque-Limiting Shaft-to-Gear Couplings

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

Torque Limiters for Chain and Belt Drives

Prevent damage from overloading. When overloaded, these limiters cause your sprocket or pulley to slip. Once the overload is removed, the limiters automatically reset.
