PROBLEM TO BE SOLVED: To provide a rolling bearing suitable for a use under high temperature non-lubrication. SOLUTION: A radial ball bearing 1 is provided with an outer ring 3, an inner ring 4, a ball 5, and spacers 7 arranged in a dispersed state in the space thereof. In a case of manufacture of the solid lubrication bearing of the radial ball bearing 1, first, a solid lubricant, a filler, and a liquid binder are kneaded together to prepare a paste-form fluid substance. After a bearing having no holder is washed and a mold release agent is applied, balls are arranged at equal intervals in a space between the outer and inner rings and a gap part formed from the inner and outer rings and the ball is filled with paste. After filling, the surface of the filler is shaped and thereafter, a filled bearing is burnt in an electric furnace at a specified temperature pattern. After cooling, the bearing is taken out from the furnace and a window to discharge wear powder, generated during rotation of the bearing, to a position where a premarked ball is present is opened. Thereafter, by effecting prerotation, smoothness of rotation is confirmed, and a film of the lubricant is uniformly formed on the ball 5 and a rolling surface for completion. |
