    Taper roller bearings are separate bearings. the inner ring with roller and cage form the inner components, and can be mounted  separately with outer ring. It has tapered raceway on inner and outer ring, and tapered rollers are mounted between the raceways.such bearing are mainly used to bear the combination load of radial and axial. The axial  carrying capacity of the bearing is depended on the contact angle a (the outer raceway angle).the larger the a ,the higher the axial carrying capacity of  the bearing  . This bearing can be classified into single-row,double-row and four-row taper roller bearing according to rows of rollers.

    Double-row taper roller bearing with a pair of outer raceway and two inner rings ,between the two inner rings there is middle spacer ring. changing  its thickness can adjust the bearing clearance. This bearing can bear radial load and bi-directional axial load at the same time,and can limit the axial displacement of shaft or housing in both directions within a range of axial clearance. Such bearings are generally suitable for medium-speed or low-speed application.

    Taper roller bearing use pressed steel plate cage,but when the size is larger,it will adopt the machined solid  cage  , which is  welded with supporting rollers(each roller has a supporting hole in its radial center)
