ROLLING BEARING AND ROLLING BEARING DEVICE

摘要

[PROBLEMS] A rolling bearing and rolling bearing device in which wear caused by relative positional displacement between a closure member (preload member), to which liquid pressure such as hydraulic oil pressure is applied, and an outer ring is prevented. [MEANS FOR SOLVING PROBLEMS] The rolling bearing has rolling bodies (34), an inner ring (33) having on its outer periphery a raceway surface on which the rolling bodies (34) roll, and an outer ring (32) having on its inner periphery a raceway surface on which the rolling bodies (34) roll and to which the load of the rolling bodies (34) acting to axially one side can be applied. At one end on the axially one side of the outer ring (32) is integrally provided a closure member (36) for closing the opening on the inner peripheral side of the outer ring (32).
