Due to the electronic control technology progress, automobile is now change to the characteristic tendency of compact structure,low energy consumption,good acceleration performance, lightweight, comfortable and convenience. Therefore, rolling bearing, as the important parts of automotive support, which must adapt to this trend. GBB bearing closely connected with those characteristics and committed to the research of automobile bearing, we have developed wheel hub bearing unit transformed from ABS pulser, long life gearbox bearing, high temperature-resistant,high speed-resistant and good sealed performance electromagnetic clutch bearing, high-speed rotation sealed ball bearings and automobile water pump bearings.
