Pulleys and Belts – BLACKHAWK Pd®

High-performance synchronous belt with aramid cords for use in rigorous synchronous drives requiring premium performance. BLACKHAWK Pd® is precisely designed and manufactured to fit many high-capacity synchronous applications. The cross-linked elastomer rubber compound is formulated to resist tooth deformity and increase tooth rigidity, increasing belt life and decreasing replacement costs. Compared to other belts in its class, Hibrex® is up to seven points harder with twice the tooth shear. Its chemical stability resists the effects of oils, coolants, heat and ozone. The Hibrex® rubber compound is reinforced with aramid tensile members for high impact strength.
