Abstract:
A deep groove ball bearing is configured so that: a pair of shoulders (22a, 22b) formed on both sides of the raceway groove (21) of the inner ring (20) are formed to have different heights, a tapered surface (23) is formed on the outer periphery of the high shoulder (22b), the end of the tapered surface (23) which faces a bearing side surface being a small-diameter end; and the flow of lubricating oil to the outside is reduced, the lubricating oil being sucked into the bearing from the low shoulder (22a) side by a pumping effect due to the rotation of the tapered surface (23) and being discharged to the outside from the high shoulder (22b) side by the pumping effect.
