Customize the bore of these flexible couplings to align uncommon shaft sizes as well as shafts that have become undersized from wear or oversized from coatings.

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

An acetal plastic spacer at the center of these couplings insulates bearings, encoders, and other shaft components from stray electric current. Use them with servomotors, which sometimes generate current that travels down the shaft and can damage circuit boards, interfere with readings, and cause wear on bearing raceways.

A flexible tire on these couplings safeguards components on your shafts by reducing vibration and shock.
