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. Also known as Oldham couplings, they 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).

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.

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.

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.

Attach these collars anywhere along your shaft, which helps when other components are already installed or you can't access the end. They clamp firmly and evenly without marring the shaft, so you can reposition or remove collars later.
