Abstract
A bearing includes a cage and rollers disposed between a first raceway surface and a second raceway surface axially facing each other. The cage includes a first guide surface and a second guide surface. The first guide surface is provided on a radially outer portion of the cage, and contacts the first raceway surface when the cage is displaced toward the first raceway surface. A clearance formed between the first guide surface and the first raceway surface is smaller than a clearance at a radially inner portion of the cage. The second guide surface is provided on a radially outer portion of the cage, and contacts the second raceway surface when the cage is displaced toward the second raceway surface. A clearance formed between the second guide surface and the second raceway surface is smaller than a clearance at a radially inner portion of the cage.
