Split-Tapered Bushings

Cast Iron

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 trade number. As you tighten the included screws, the bushing grips the shaft and pulls it into the sprocket or pulley.

Machine Key—Bushings with a machine key fit into a matching keyway on a sprocket or pulley for high-torque applications.
