Flat belts with rubber coatings are an important component for drives. Thanks to the different versions of these drive belts, specific requirements, applications and machine designs can be realized. Rubber-coated flat belts have different plastic tension members, which are characterized by their excellent price-performance ratio. Flat belts made of polyurethane have either steel or aramid tension cords, which guarantee high flexibility with high tensile strength. PU flat belts are a maintenance-free, low-noise and space-saving alternative to chains and cable pull systems. Applications for these polyurethane flat belts include lifting systems, elevator systems and fitness equipment. Flat belts made of polyurethane are primarily used to realize the smallest bending radii or frequent bending changes. The drive belts have uniform elongation values, breaking forces and thickness tolerances over their entire length.
