A solid lubricantis formed by molding and firing powder that includes amorphous and self-sintering carbon material powdergraphite powderand a binderThe solid lubricant has high material strength and hardness, and also excellent impact resistance and wear resistance.

Solid lubricant and solid-lubrication rolling bearing

A separatorincluding a solid lubricant is disposed between adjacent rolling elements. Relative movement of the adjacent rolling elementsand the separatorin a direction of separating apart in a circumferential direction is restricted by restricting members, and the restricting membersare disposed at plural locations in the circumferential direction. A minute gap &#x3b1; is provided between the adjacent restricting members, to allow relative movement therebetween. This can provide a solid-lubrication rolling bearing capable of stably preventing rotational locking and unintended disassembling of the bearing for a long period.
