QD Bushed Sprockets \u2014 Maximum Bore Capacity, Rapid Field Replacement<\/h2>\n

QD (Quick-Disconnect) bushed sprockets accommodate the largest shaft diameters in the ANSI range. The QD bushing system uses a flanged, straight-bore bushing with cap screws that can be reversed for installation or removal. Available in ANSI #40 through #240 with QD bushing sizes from JA through W2. Bore capacities up to 150mm+ depending on bushing size. Designed for heavy mining, cement, steel, and port applications where large shafts and maintenance accessibility are critical.<\/p>\n

\nQD vs Taper-Lock?<\/summary>\n
QD handles larger bores and is standard on heavy-duty ANSI sprockets. Taper-lock provides better concentricity for high-speed applications. Both allow rapid installation.<\/div>\n<\/details>\n
\nBushings sold separately?<\/summary>\n
Yes. All QD bushing sizes stocked independently.<\/div>\n<\/details>\n
\nMax bore?<\/summary>\n
W2 bushing handles up to 150mm+. Contact us with shaft diameter.<\/div>\n<\/details>\n
\nISO metric QD?<\/summary>\n
QD is primarily an ANSI standard. For ISO metric, taper-lock bushings are the preferred equivalent.<\/div>\n<\/details>\n
