The utility model relates to the technical field of bearings, and in particular relates to a novel double-row tapered roller bearing which comprises an annular connecting piece, wherein outer bearing rings, tapered rollers and inner bearing rings are symmetrically arranged on two sides of the connecting piece; annular tapered roller paths are arranged on both the outer bearing rings and the inner bearing rings; tapered retainers are arranged inside the roller paths; tapered rollers are uniformly distributed on the retainers; the inclined angle of the tapered retainers is 5-20 degrees; sealing rings are arranged at one end of each retainer; stopping grooves are formed in the outer sides of the outer bearing rings and the connecting pieces. The novel double-row tapered roller bearing is simple in structure and reasonable in design, the outer rings and the inner rings can be respectively arranged, joint action of axial load and radial load can be simultaneously born, and due to the arrangement of the stopping grooves and the sealing rings, the stopping property and the sealing capability are both improved.
