Dura-Flex® couplings
 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.
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
