Double row tapered roller bearing can bear bidirectional axial load while bearing radial load.

There are two basic types of double row tapered roller bearings: one is double outer ring and a double raceway inner ring structure, which has poor steel; The other is a double raceway outer ring and double inner ring structure, this structure due to the increase of support width and good steel, in the occasion of large overturning moment should be selected this structure, there is a ring between the double outer ring or double inner ring.
