ABSTRACT:
Bearing devices which rotatably support a shaft in a bearing having a plurality of radial projections formed on either the inside peripheral surface of the bearing or the peripheral surface of the shaft are discolsed. The bearing has an oil film formed between the projections and the mating part opposite to the projections for supporting the shaft. The projections are adapted to face the mating part with a specified area sufficient to cause a specified oil film dynamic pressure effect to occur. In one form of the invention, the projections are formed of an oil impregnated sintered metal, the part of the surface of the projections facing the mating part having been subject to a filling-up process.
