PROBLEM TO BE SOLVED: To provide a rolling bearing which is free from inhibition of rotation because a spacer is caught by the bearing, has not such a risk that the spacer falls, hardly causes vibrations, can obtain smooth and safe rotations and has high reliability and a low cost.SOLUTION: A solid lubrication rolling bearing includes an inner ring 2, an outer ring 1, a rolling body 3, a spacer 4 which contains a solid lubricant made of selected material and a retainer 5 having pockets which store the spacer 4 and the rolling body by setting at least one spacer 4 and one rolling body 3 as a unit. Thereby, the solid lubrication rolling bearing which has not a risk of falling and breakage, hardly causes vibrations and can obtain smooth and safe rotations is provided. |
