QD Bushings

QD (quick detachable) bushings mount sheaves, sprockets and pulleys to shafts with a tapered, split design that clamps tightly and comes off easily. They allow one sheave to fit many shaft sizes and make drive maintenance much faster.

QD Bushing Features

• Tapered clamping fit – secure grip without set screws marring the shaft
• Standard series (JA, SH, SDS, SK, SF, E, F) – broad shaft size range
• Keyed bores – standard and metric sizes
• Easy removal – jacking screws free the bushing
• Steel and ductile iron – for industrial drives

Installation Tips

Match the bushing series to the sheave or sprocket hub, then select the bore and keyway for your shaft. Tighten cap screws evenly to the specified torque, without lubricating the tapered surfaces. Recheck torque after initial run-in.

Centro carries QD bushings for sheaves, sprockets and pulleys in common series and bore sizes.
