The BRECO PU timing belts polyurethane timing belts
PU belt material can be divided into chloroprene rubber, plus fiber rope belt, polyurethane, plus wire timing belt teeth shaped into trapezoidal tooth and arc tooth two categories, according to the row of cloth can be toothed divided into single-sided tooth synchronous belt and Double Sided Timing Belt.
PU timing belt has excellent flex resistance, elongation, strong advantages, but also with oil, heat resistance, aging resistance, ozone resistance, resistance to cracking and excellent performance. Existing timing belt more than 30 kinds of models, more than 1000 kinds of specificati***, and supporting the timing belt pulleys, In addition to the conventional models, but also manufacture the special specification model of the timing belt is designed for users to meet the special use requirements of the user.
