Tapered roller bearing:   Introduction: The inner ring and outer ring of tapered roller bearing have tapered raceway,and between tapered raceway mounted tapered roller. Tapered rolelr bearing is mainly used for carrying radial and axial combined load which is mainly radial load.The axial load carrying capacity of bearing is determined by contact angle α, the bigger α is,the bigger axial load carrying capacity is.Tapered roller bearing is a separable bearing:inner assembly is consisted of inner ring with roller and cage, which can bemounted with outer assembly separably.   Type: Single row tapered roller bearing: The bearing can only limit one direction axial displacement of axis or case shell and carry one direction axial load. With the radial load action, the axial force produced inside bearing should be balanced. Two bearing should be face-to-face amounting or back-to-back amounting. Double row tapered roller bearing: The tapered bearing can carry radial load as well as bidirectional axial load, and can limit bidirectional axial displacement of axis or case shell within the axial clearance of bearing. Four row tapered roller bearing: The bearing's feature is mostly the same as double tapered roller bearing, but can carry more radial load than double row tapered roller bearing, lower limit rotation rate. Mainly be used in heavy machinery, such as roll mill.   Cage: Tapered roller bearing generally use die stamping steel plate basket cage, also can use machined solid cage if its dimension is bigger.   Series 30202 30215,30302 30313,31306 31311,32007 32026,32204 32222,32304 32312,33011 33117,33205 33218,32007X,32026X and so on.......
