Product Detail
30300 bearing is tapered roller bearing, which is a bearing unit composed of machined tapered-inner & outer rings and tapered rollers. It is usually used as supporting bearing, and can simultaneously baer bigger radial & axial force. Because of tapered-roller number, it has very high dynamic load & static load, and also high rigidity. It is widely used in automobile machine tool, metallurgical and textile machinery; driving shaft, gearbox and other location & supporting location.
