Due to the development of electronic technology, automobiles are developing in the direction of practical performance such as compact structure, low energy consumption, good acceleration performance, light weight, comfort and convenience. GBB closely combined these characteristics together and are committed to the research and development of automotive bearings. GBB have developed hub bearing units with inherited ABS pulse generators, long-life cylindrical bearings, high-temperature resistance, high-speed and good sealing performance electromagnetic clutch bearings, etc., these bearings are with strong carrying capacity , good wear resistance, moderate elastoplasticity, maintenance-free, and longer service life.
