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 (QT) hubs.

Dura-Flex Couplings Product Specifications

  • Bore-to-size (BTS), Sure-Grip bushed (QD), and Taper-Lock® hubs are available
  • Specially designed “split-in-half flex element” moves stress away from bond, extending flex life
  • Directly interchangeable with similar couplings for fast and easy replacement
  • One spacer size eliminates problems with varying between-shaft spacings
  • Requires no lubrication, minimizing maintenance and downtime
  • Flexible polyurethane material offers superior chemical, dynamic, and weathering properties
