Dura Flex

Dura Flex

TB Wood’s Dura-Flex couplings "split-in-half" element design allows for easy element installation/replacement without moving connected equipment or disturbing the shaft connection.

Spacer design can accommodate a large range of shaft spacing with few parts. Patented design of the urethane bond to the leading edge of the steel shoe bolted to the hub, minimizes bond stress for long coupling life.

These couplings are highly flexible and able to accommodate shaft misalignments (1/16" parallel misalignment and 4 ̊ angular misalignment) while minimizing torsional vibration and preventing damage to connected equipment.

Specially formulated polyurethane material provides superior weathering, chemical resistance, and dynamic properties
