<p>PROBLEM TO BE SOLVED: To improve a bearing life of a solid lubricant rolling bearing whose life might be limited in light of a structural restraint by reviewing both of a bearing constitution of the solid lubricant rolling bearing and a composition of a solid lubricant.SOLUTION: A separator 8 made of a solid lubricant is arranged between adjacent rolling elements 7. Powder containing amorphous carbon material powder having a self-sintering property, graphite powder and a binder is molded, sintered, and used as a solid lubricant. Relative movement of the adjacent rolling elements 7 and the separator 8 in a direction away from a circumferential direction is restrained by a restraining member 10, and the restraining members 10 are arranged at plural portions in the circumferential direction. A minute gapαis provided between the adjacent restraining member 10, so as to allow the relative movement of the members.</p> |
