Combine with a machine key to transmit torque to gears, sprockets, and other power transmission components.
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.
In addition to diameter tolerances that are twice as tight as standard keyed shafts, these shafts include a traceable lot number and test report. Use them with machine keys to transmit torque to gears, sprockets, and other power transmission components.
Designed to grip evenly around your shaft, clamping couplings provide more holding power than set screw couplings without marring the shaft.
These couplings have the gripping strength to handle higher torque than most other couplings.
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.
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.
Set screws bite into your shaft to hold these couplings in place.
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.
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.
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.
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.
Each hub includes a set screw (unless noted), which bites into your shaft to hold the coupling in place.
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.
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.
Designed to grip evenly around your shaft, these couplings provide more holding power than set screw couplings without marring the shaft.
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.
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.
With a rugged roller-chain design, these couplings provide excellent torque and angular misalignment capacities.
With a rigid gear design, these steel couplings transmit more torque than other couplings of the same size.
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.
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.
Three tapped counterbored holes and three through-holes provide mounting flexibility.
Install these collars anywhere on a shaft without removing components or having access to the ends of the shaft.
These metal collars are stronger than plastic shaft collars.
With larger screws than those found on standard clamping collars, these provide a stronger grip on your shaft without using additional screws.
