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.
304 stainless steel bushings are often used in food-processing plants and other frequently-cleaned areas because washdowns and humidity won’t corrode them. They have a pilot hole instead of a finished keyway, so you can bore them to the exact dimensions of your shaft.

Split-Tapered Bushing-Bore Sprockets for ANSI Roller Chain


Since these sprockets grip bushings more tightly than taper-lock sprockets, they’re often used in high-torque applications. The same sprocket can be used with different shaft diameters; choose a compatible split-tapered bushing with the bore size you need.
Sprockets for P1- and Q1-Style bushings have a keyway that fits a matching key on the bushing.
