The present invention provides a rolling bearing that can be applied to a small motor or the like in which deterioration and performance degradation are unlikely to occur and sound is a problem. SOLUTION: A plurality of rolling elements 3 that are arranged to freely roll between inner and outer rings 1 and 2, a retainer 4 that holds the rolling elements 3, and a seal 5 that seals between the inner and outer rings 1, 2. The grease 6 containing 2 to 50% by weight of microcapsules is enclosed in the inner part of the cage 4 or the seal 5 in an amount of 40 to 60% by weight of the specified amount, and the remaining 60 to 40% by weight of microcapsules Grease 7 not blended is enclosed in raceway surfaces 1a and 2a of inner and outer rings 1 and 2. In the microcapsule, a lubricating oil or a lubricant additive is contained in an amount of 10% by weight or more based on the total weight of the capsule. [Selection] Figure 1 |
