TB Wood's® Couplings

Sure-Flex®* couplings *

Product Description

TB Wood’s®* Sure-Flex®* couplings use 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.

Product Features Lubrication-free design provides quiet, reliable performance Flexible sleeves available in EPDM, Neoprene, and Hytrel Fast and easy installation without bolts, gaskets, covers, or seals Uniquely designed teeth and lateral flexibility accept both parallel and angular misalignment without wear.

Choose from an extensive offering of sizes, using BTS, bushed, clamp and spacer flanges Four-way flexing action absorbs extreme torsional shock and vibration.

TB Wood's® Sure-flex® & Dura-flex®

Dura-Flex®* couplings *

Product Description

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.
