摘要： A bearing and a method for fabricating a bearing. The bearing is intended to be used in office automation equipment and the like is improved in impact resistance and load capacity. Its rotational accuracy will not deteriorate in long-term use and its quietness can be maintained over a long period of time. The bearing is an anti-friction bearing located between portions supporting a load and in relative motion to each other. The anti-friction bearing has an outer ring of 30 mm or less in diameter, in which high carbon chromium bearing steel constituting the anti-friction bearing includes the following compositions: C of 0.90-1.30 wt %, Si of 0.40-1.20 wt %, Mn of 0.90-1.0 wt %, and Cr of 0.90-1.70 wt %. After quenching, the tempering temperature used for this bearing is maintained in the range of 170° C. and 250° C. so that the amount of retained austenite in the surface layer after heat treatment is stabilized at 6 by volume or less.

摘要： Residual fine foreign matters are infallibly removed when manufacturing bearing parts. A removal process of residual fine foreign matters is taken before a high precision water-washing process in a manufacturing process of each component of a rolling bearing. Accordingly, residual fine foreign matters generated in a cutting process, a heat-treating process and a grinding process are removed, including metal powder like a metal chip and falling pieces of bearing components. In the removal process of residual fine foreign matters, ground pieces of corn-cob as a raw material are used for a grinding medium. Thus, damages to a surface of rolling bearing parts may be minimized during the removal process. Moreover, the medium is likely to accommodate to a surface of bearing parts, so that residual fine foreign matters may be effectively removed.

摘要： Strength and rigidity are provided to a retainer so as to prevent the retainer from being deformed by force and sliding friction generated by rolling elements thereby preventing occurrence of retainer noise of a rolling bearing and aggravation of NRRO. A retainer is entirely formed of synthetic resin, and a highly elastic synthetic resin is used for the claws which are required to be highly elastic. A part below a boundary L of a body portion is formed of resin with sufficient strength and rigidity to prevent deformation due to force and sliding friction of rolling elements, thus preventing decline in strength of the retainer as a whole which may occur because of the use of resin with high elasticity for the claws. The strength of the retainer as a whole is fully ensured by the body portion, thus improving various functions, contributed by the rolling bearing.

摘要： The present invention provides a rolling bearing that prevents retainer noise and NRRO deterioration thereof by imparting strength and rigidity to a retainer so as to prevent it from being deformed by force from rolling elements and sliding friction. An annular plate is connected to a retainer by bosses. Due to the rigidity of the annular plate, the strength and rigidity of the retainer can be improved. Additionally, since the bosses are fixed to grease reservoirs arranged at an equal spacing therebetween on the circumference of the retainer, the strength and rigidity of the retainer can be equally improved over the entire circumference thereof.
