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.
