QD Bushing Sprockets \u2014 American Standard<\/h2>\n
\n
\n

The defining advantage of QD over setscrew bore for heavy American drives is the self-locking taper grip combined with the self-releasing split bore \u2014 loosening the cap screws and reversing them into the removal holes ejects the bush and sprocket from the shaft in one action, without any puller, hammer or heat. 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

The QD bush series covers shaft sizes from 5\/8″ (JA bush) to 4-7\/16″ (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.
