Torsional couplings are flexible couplings that offer a number of benefits to mechanical systems. These couplings can protect your driveline and increase the life of downstream equipment by dampening vibration. Additionally, torsional couplings operate as flexible couplings by design. This feature helps them to compensate for radial, axial, and angular misalignment. For additional information about torsional couplings, contact our team directly.
Dura-Flex Couplings
TB Wood's Dura-Flex couplings are manufactured with precision and available from Clutch Engineering. The element is light weight and absorbs shock loading and torsional vibration. These high-performance coupling products have a two-piece element that makes installation easy. This ease of installation can also reduce the downtime of your machinery, for the benefit of your bottom line. Coupling must be guarded, both to prevent any contact with the rotating parts and to contain the coupling components should they fail.
