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

Tighten the set screws to fasten these couplings to your shaft. Set screws bite into the shaft to hold the couplings in place. All are lightweight, corrosion-resistant aluminum.

Each hub includes a set screw, which bites into your shaft to hold the coupling in place. Also known as Oldham couplings, these couplings have a slotted disc that allows hubs to slide independently—good for applications with parallel shaft misalignment. They also allow zero backlash (no play) and never need lubrication.

A complete coupling consists of two hubs and one disc (each component sold separately). Hubs are made of aluminum, so they’re lightweight and have good corrosion resistance.

Acetal Disc—Acetal discs stand up to high twisting forces.

Nylon Disc—Nylon discs have excellent vibration and shock absorption.

PEEK Disc—PEEK discs have excellent impact resistance and the chemical resistance to withstand a variety of acids and other harsh substances.

The included set screw holds the coupling in place. Good for precision motor and pump applications, the spider-shaped cushion reduces shock and compensates for minor shaft misalignment. Couplings allow zero backlash (no play).

A complete coupling consists of two hubs and one spider (each component sold separately). Hubs are lightweight, corrosion-resistant aluminum. Spiders are polyurethane for fair vibration damping and good chemical resistance.

Able to handle high twisting forces as well as misalignment, these couplings are good for high-performance servomotor applications. Couplings are aluminum and stainless steel for corrosion resistance and allow zero backlash (no play). They grip evenly around your shaft for a strong hold without marring the shaft. Tighten the clamping screws to secure.

Also called double-loop couplings, these have a flexible center that reduces vibration and compensates for high parallel and angular shaft misalignment. They allow zero backlash (no play) and will run smoothly and quietly. Fasten to your shaft by tightening the set screws, which bite into the shaft to hold it.

Connect shafts and ball screws to high-speed servomotors and stepper motors—these shaft couplings handle four times more speed than standard servomotor couplings. They’re often found on high-torque motors that frequently start and stop, such as those used with packaging machines, press brakes, and semiconductor manufacturing equipment.

With aluminum hubs joined by a flexible fluoroelastomer or Buna-N core, these shaft couplings dampen vibration and adjust for misalignment. When machines accelerate and decelerate quickly, these couplings remain stiff to maintain accuracy and repeatability, which prevents equipment from moving out of place. They also resist backlash, meaning all of the turning force from the motor is passed on to the connected shaft. The core resists water, petroleum-based chemicals, and inorganic acids while also insulating bearings, encoders, and other shaft components from stray electric current. Clamping screws provide hold without marring shafts; they’re useful in applications where shafts are frequently assembled and disassembled.

With a bellows between two hubs, these couplings handle all types of misalignment and are good for precision stepper and encoder motion-control applications. All have lightweight aluminum hubs and a stainless steel bellows for corrosion resistance. Couplings allow zero backlash (no play) and grip evenly around your shaft for a strong hold without marring the shaft. Tighten the clamping screws to secure.
