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.  Sure-Flex® couplings are available in both closed coupled and spacer coupling designs.
