Spherical roller bearing is comprised of inner ring with double raceway,double row spherical rollers ,cage and big outside spherical ring. It can alignment center of spindle by itself and bear bidirectional axis loads, at same time ,bear bggish radial load.straight hole and tapered hole are two types of Inner ring of spherical roller bearing. Inner ring with tapered hole can be fixed on adapter steeve or shirk steeve for installing on any position of plain shaft or multidiameter. Spherical roller bearing with adapter steeve recur to tapered hole and adapter steeve to adjust radial internal clearance. Spherical roller bearings are used by equipment of petro, metallurgy,mining, construction,heavy machine field etc.
Except basic type of spherical roller bearing, there is also derivative structure,like tapered inner ring,with adapter steeve and double shield ,CA,CC,CAC, and spherical roller bearing with seal.
