It boast the advantages of reduced vibration, reduced noise level, increased power, 100 percent tracking in both running directions without flanges, continuous tooth engagement also in a tangential belt-pulley arrangement and smooth interaction with idler and tensioners running on the toothed side of the timing belt eliminating tooth jumping, based on the overlapping tooth arrangement. The timing belts are available as open ended, spliced, welded endless, and truly endless polyurethane versions. They are constructed of abrasion resistant polyurethane (92 Shore A) and high-strength steel or stainless steel tension members.
