Wear-Resistant Sprockets for ANSI Roller Chain
Hardened teeth give these steel sprockets increased wear resistance for a long service life. Mount them onto your shaft and secure with a set screw—no machining necessary.

Taper-Lock Bushings
Mount these hubless bushings flush into your sprocket or pulley for a slim profile with no protruding screws. They are for use with taper-lock sprockets of the same bushing style. As you tighten the included set screws, the bushing grips the shaft and pulls it into your sprocket or pulley.

Split-Tapered Bushings
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. They're for use with split-tapered sprockets and pulleys of the same bushing style. As you tighten the included screws, the bushing grips the shaft and pulls it into the sprocket or pulley.
Bushings with a machine key fit into a matching keyway on a sprocket or pulley for high-torque applications.
