In row tapered roller bearings,
The outside of the large end surface of the tapered roller is located at the intersection of the conical raceway surface formed in double rows on the inner peripheral surface of the outer ring and the cylindrical seal support surface continuous to the large diameter end of the raceway surface. A sealed double-row tapered roller bearing, characterized in that an engagement groove is provided in which a portion of the circumference can be accommodated, and the inner diameter of the seal support surface and the circumscribed diameter of the large end surface of the tapered roller are similar.
