QD Bushings (Quick Detachable bushings) are industry-standard tapered bushings designed for fast installation, superior shaft grip, and easy removal. Built to provide a secure, concentric fit between mounted components and drive shafts, QD bushings are commonly used with sprockets, pulleys, sheaves, gears, and chain couplers in industrial, agricultural, and power-transmission applications.

Featuring a flanged design with precision taper, QD bushings deliver exceptional holding power while allowing mounted components to be swapped or serviced without damaging the shaft. Each bushing includes removable cap screws that function for both tightening the bushing onto the shaft and releasing it when disassembly is required.

Available in popular styles such as JA, SH, SDS, SK, SF, E, F, J, M, N and more, QD bushings accommodate a wide range of bore sizes and keyway options. Manufactured from high-strength steel and machined to ANSI standards, they offer long-lasting performance in high-torque and heavy-duty environments.
