The rolling bearing further includes an oil reservoir portion provided to an end portion of the outer ring in the axial direction and configured to store lubricant between the oil reservoir portion and the outer ring.

Abstract: A cage assembly is moved in the axial direction to approach an inner ring from a small rib portion side. An inner ring assembly is constituted by causing tapered rollers of the cage assembly to climb over a small rib portion to be fitted on an inner raceway surface, and then is assembled to an outer ring. In this method, a jig is provided adjacent to the small rib portion. The jig includes recessed grooves that are formed in the outer peripheral portion of the jig and that enable contact of the respective tapered rollers. Each recessed groove has a recessed arcuate shape in cross section. The tapered rollers of the cage assembly are caused to slide radially outward along the recessed grooves, so that the diameter of cage is increased. Accordingly, the tapered rollers climb over the small rib portion to be fitted on the inner raceway surface.

Abstract: In a tapered roller bearing, a large rib is provided at one end of an inner ring in the axial direction, and projects radially outward. A lubricating oil holding member is integrated with an outer ring, and disposed at a position overlapping the large rib in the radial direction.
