Taper Bushings
Taper Lock Bushings: Fit flush into taper bushing-bore sprockets (sold separately). Align and tighten the set screws; as they tighten, the bushing contracts and grips the shaft and bore.
QD Tapered Bushings: These Sure-Grip bushings meet Mechanical Power Transmission Association standards, offering compatibility with various shaft diameters. (Sold separately; choose the correct bore size.)
H Tapered Bushings: Designed with dual cuts on the tapered sides, they expand for a tighter fit and improved leverage. Tighten the cap screws to secure the shaft within the sprocket or pulley.
