Sure-Flex is a TB Wood’s original! Sure-Flex Couplings utilize a rubber (EPDM or Neoprene) or Hytrel™ thermoplastic flex element (sleeve) to transmit torque and accommodate shaft misalignments. Sure-Flex couplings have exceptional torsional flexibility, and the 4-way flexing action absorbs virtually all types of shock, vibration, misalignment, and end float. Sure-flex couplings are an excellent choice when low cost, high flexibility, vibration damping, and easy installation are primary concerns.
