Many bearing user don't understand clearly about spherical roller bearing installation, now let me talk about this,spherical roller bearing is consist of inner ring,outer ring,spherical rollers and cage,there are two raceway in the inner ring and one spherical raceway in the outer ring,the center of curvature of the raceway in outer ring is coincident with the centre of the bearing,so spherical roller bearing have the self-aligning function like the self-aligning ball bearing, when deflection occured between shaft and housing ,it can adjust the capacity and shaft load in double directions,Large radial load capacity are used in high capacity and shocked load, the tapered bore inner ring of the bearings can be installed directly,or using an adapter sleeve to install on the cylindrical shaft,the cage can be Pressed steel,brass materials.
