Claims

[Scope of utility model registration request]

(1) A distance piece with a lubricant passage that communicates with the inside and outside of the bearing is interposed between the small end faces of the outer rings of the pair of bearings, and a distance piece is installed on the large end face of the outer ring of the bearing, and on the inner diameter surface of the outer ring. A seal ring is provided with a radially inward flange so as to form a space with a single cross section toward the inner ring, and an oil seal is installed in the space with a single cross section. The flange side end is brought into sliding contact with the outer circumferential surface of the inner ring extension that extends in the axial direction from the large end surface of the outer ring, and the inner and outer parts of the bearing are connected to the seal ring on the inner side of the bearing from the radially inner flange of the ring. A sealed multi-row sealing type, in which a lubricant passage communicating with the distance piece and the seal ring in the radial direction is formed, and one of the lubricant passages in the distance piece and the seal ring is used as a lubricant supply passage and the other as a lubricant discharge passage. In the tapered roller bearing, an axial flange is formed at the inner diameter end of the radially inner flange of the seal ring, facing toward the inside of the bearing and having a slight clearance from the outer circumferential surface of the inner ring extension. A sealed multi-row tapered roller bearing, characterized in that the opening position of the lubricant passage is located on the outer peripheral surface of the axial flange.

(2) The sealed multi-row tapered roller bearing according to claim (1), wherein the outer diameter of the axial flange is substantially the same as or slightly smaller than the outer diameter of the small flange of the inner ring. (3) The sealed multi-row tapered roller bearing according to claim (1) or (2), wherein a lubricant reservoir is formed on the inner surface of the radially inner flange.
