Twin Spring Coupling LLC Replace universal joints, jaw couplings, beam , bellows and elastomeric couplings

Twin Spring Coupling produce power transmission coupling technology, replace universal joints, jaw couplings and elastomeric couplings with a simple 1 piece design. Contains no bearings so no need to be constantly greasing, no worn bearings to replace. Jaw coupling inserts have a 1 degree of less misalignment potential, TSC can flex to 45 degrees, and don't need to replace the spider inserts like

you do with the Buna-N, NBR, Urethane, Hytrel or Bronze elastomeric ins. As flexible as a universal joint but with the torsion strength and high speed to replace jaw couplings and other elastomeric couplings. Replaces couplings made by Spicer, Lovejoy, Moog, SKF, Neapco, Ruland, Belden, Altra Motion, TB Woods, Rexnord, Boston Gear, Martin, Curtis, SIT, KTR and Guardian couplings.
