TB Wood’s has recently introduced its Sure-Flex and Dura-Flex online coupling selector at The enhanced online tool allows users to quickly and easily select the right coupling for a specific application.

Users simply enter required application data and any special requirements needed. A list of several recommended couplings, including list prices, rating and dimensional data for each, is instantly displayed based on the specification criteria provided.

When a specific coupling is selected for further review, additional information is presented including coupling description, assembly drawing, part number, bill of material, and link to downloadable specifications and CAD drawings.

TB Wood’s Sure-Flex couplings utilize a rubber (EPDM), neoprene, or Hytrel sleeve and have exceptional torsional flexibility. Their 4-way flexing action absorbs virtually all types of shock, misalignment, and end float. With Sure-Flex couplings, the need for lubrication and maintenance is eliminated. As a result, these couplings provide clean, dependable, and quiet performance for a variety of applications. Uniquely designed teeth and lateral flexibility accept both parallel and angular misalignment without wear. Models are available in an extensive offering of sizes, using BTS, bushed, clamp and spacer flanges


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