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

A mounting flange prevents movement during tightening.

Made from stainless steel or plated with nickel, these bushings resist corrosion. A mounting flange prevents movement during tightening.

A toothed slot lets these bushings contract for insertion into the bore of your sprocket or pulley and then expand for a snug fit.

Reduce the ID of sprockets, pulleys, and gears in low-torque applications.

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

Replace worn bushings and quickly change IDs without needing to repeatedly use a lever press. Instead of pressing bushings in and out of your jig fixture, which can cause damage, these bushings slide in and out of sleeves.

Insert these bushings into a drilled hole and twist the lock ring to secure. Reusable and easy to replace, they are held in in place by a separate locking part.

The knurls resist force and provide better holding strength than serrations. Encase in plastic tooling.
