Dura-Flex® Couplings | TB Wood's

TB Wood’s Dura-Flex® couplings are designed from the ground up using finite element analysis to maximize flex life. Perfect for a wide variety of applications -- including those with uniform to heavy shock loads -- Dura-Flex® couplings employ a light weight element that absorbs shock loading and torsional vibration. These couplings are available in stock bore-to-size (BTS), Taper-Lock® and Sure-Grip® bushed (QD) hubs.
