PROBLEM TO BE SOLVED: To provide a rolling bearing capable of suppressing ill effects due to the use of a solid lubricant and agitation resistance due to the use of liquid lubricant without increasing its size and weight.SOLUTION: The rolling bearing includes an inner ring 10, an outer ring 20, and a plurality of rolling elements 31. On at least one of an inner ring raceway surface 12 and an outer ring raceway surface 22, a number of inside dimples 26 where liquid lubricant 27 is reserved and a number of outside dimples 28 where a solid lubricant 29 is reserved are formed. The number of inside dimples 26 are arranged on the side close to a contact region 13 out of the contact region 13 and a non-contact region 14 of the raceway surface with the rolling elements 31, and the number of outside dimples 28 are arranged outside the number of inside dimples 26. |
