30*62*17.25mm metric taper roller bearing 30206
The tapered roller bearing is to bear the combination of radial and axial load but mainly afford radial load. The loading capibility is determined by the raceway angle of outer ring, the larger angle afford larger load. This kind of bearings can be seperated and it can be divided into single-row and double-row tapered roller bearings by the number of columns. The clearance for single-row tapered roller bearing should be adjusted by the customers when installation. For the double-row tapered roller bearings,the clearance has already set by the manufacture before ex-factory. Tapered roller bearing has taper shaped inner ring and outer ring raceway,and the roller elements arrange between them. All projection lines from the surface of rollers meet at the same point on bearing axis. This design makes tapered roller bearings particular suitable for combined (axial and radial) loads.The axial loading capacity is determined by the contacting angle α, the bigger angle for α, the larger axial loading capacity is. Tapered roller bearing is usually a seperated bearing, that is,the inner ring assembly including roller and cages, is seperated installed with the cup.
