The tapered barrel on these bushings is split on both sides, allowing them to contract more tightly around the shaft than quick-disconnect and taper-lock bushings.

Mount these hubless bushings flush into your sprocket or pulley for a slim profile with no protruding screws.

Also known as Trantorque bushings, these tighten with a twist of the collar nut—no screws needed.

Each hub includes a set screw (unless noted), which bites into your shaft to hold the coupling in place.

Each hub includes a set screw, which bites into your shaft to hold the coupling in place.

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 for use in food-processing applications, where a fraying spider could contaminate a batch, these couplings have a metal-detector-grade rubber spider. Small pieces of metal inside the rubber will set off a metal detector, alerting you to the problem.

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