For drives on grain elevator head shafts, conveyor tail pulleys, aggregate plant drives or any other high-maintenance position where the sprocket must be pulled every season or every major service, QD mounting is the industry standard in North America.<\/p>\n<p style=\"font-size: clamp(14px,1.6vw,16px);\">The QD bush series covers shaft sizes from 5\/8&#8243; (JA bush) to 4-7\/16&#8243; (M bush). All Korea Ever-Power QD sprockets are bored to the standard QD taper profile and accept bushes from any QD-compliant supplier. The sprocket hub is the same C45 carbon steel as the standard bore range, with ANSI B29.1 induction-hardened tooth profile. Simplex, duplex and triplex available for all chain sizes in the range.
