PROBLEM TO BE SOLVED: To provide a rolling bearing which prevents that the bearing is damaged by a shock during rotation to cause abnormal vibrations on the bearing and a spacer falling, in a spacer type solid lubrication bearing in which the spacer made of solid lubrication material is arranged between rolling bodies with respect to the rolling bearing used in an environment of high temperature, high vacuum or the like.SOLUTION: A solid lubrication rolling bearing includes an inner ring 2, an outer ring 1, a rolling body 3, a spacer 4 containing a solid lubricant made of selected material and a retainer 5 having pockets which store the spacer 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 no risk of falling or breakage, hardly causes vibrations and can obtain smooth and safe rotations is provided. |
