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.

Transfer torque directly from a shaft to a hub.

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

Tighten just one set screw to clamp these bushings evenly around your shaft. The screw forces hydraulic fluid in between the double-walled sleeve, expanding the two walls against the shaft and the hub of your sprocket, pulley, or gear for a tight hold.
