Akron, Ohio-Goodyear Engineered Products has introduced a line of polyurethane timing belts for uses in linear motion, conveying and power transmission.
"We now offer straight-tooth polyurethane, offset-tooth, or helical, polyurethane and rubber belts, to help our distributors grow their businesses as one-source suppliers," said Michael Lyons, marketing manager for Goodyear's industrial power transmission products, in a 4 Jan Goodyear announcement.
These new straight-tooth synchronous belts complement the company's industrial timing belt products, according to Lyons.
Straight-tooth PU belts can perform better than rubber and offset-tooth polyurethane synchronous belts in specific uses. "The new polyurethane belts are more resistant to cuts, tears, abrasions and flex fatigue," Lyons said, adding that they also have higher load bearing capacity, resist mould and ozone degradation and can be easily coloured.
Goodyear says its new steel-cord reinforced belts are supplied in three forms: first as open-end rolls in 325-foot (99-m) lengths. Alternatively, welded or jointed belts are made from roll material that is cut to length and spliced, while endless belts are made using one long continuous cord with no splice or welding, offering extra cross-sectional strength, the Akron-headquartered belt maker said.
Belts made with DuPont's Kevlar aramid reinforcing cord are also available to beat corrosion in high humidity applications, such as car washes, Goodyear points out.
Lyons said the polyurethane belts, available in a broad range of the most popular tooth pitches, can be used in many industries, including package handling, making electronic components, automatic sliding doors, vertical storage retrieval and power transmission."
