PROBLEM TO BE SOLVED: To provide a porous solid lubricant filled bearing having superior lubricity and durability under high temperature and high speed circumstances. SOLUTION: The porous solid lubricant filled bearing 1 is provided with an inner ring 2, an outer ring 3, and rolling bodies 4 interposed between the inner and outer rings, and a porous solid lubricant 5 is filled up around the rolling bodies. The porous solid lubricant is formed by baking a mixture including at least a resin and lubricant, and the lubricant is impregnated into a sintered body of the resin. The combination rate is the lubricant of 10-150 points weight to the resin of 100 points weight. The resin is a thermoplastic elastomer, a thermoplastic polyurethane elastomer in particular, or a thermoplastic polyester elastomer, and is prepared as a resin pellet with one side of 0.01-1 mm. The aspect ratio of the resin pellet is 2-50. COPYRIGHT: (C)2008,JPO&INPIT |
