The structure of deep groove ball bearing is simple.And it is convenient to be make use .enjoying high rotate speed.the deep groove ball bearing support radial load and some axial load.when the clearance be added ,It own the same character as the angular contact ball bearing. Competing with the other types of bearing owning the same dimension,it enjoys high rotate speed , super precision,low friction coefficient.it抯 the one of good choosen. Besides the essential spec60000,there are deep groove ball bearing with the shield and the seal.(60000-Z ,60000-2RS) and the other specs .such as 60000V ,600000. This kind of bearing is widely used in vehicle, motor, measure instrument, mining , engineering machine.etc.
