摘要：A bearing is provided which can be sufficiently processed by a usual NC grindingmachine, and attain a life period that is substantially equal to that of a bearing having a
theoretical crowning shape which is derived from the elastic contact theory, even whenthe bearing is used in a portion to which a heavy load or a high torque load is applied. Asmeans for realizing such a bearing, a generating line of a rolling surface of a roller or araceway surface of an inner or outer race is divided into a plurality of zones, and theshape of the generating line is approximated to a special curve shape which is
theoretically derived, by a plurality of circular arcs which are contacted with each otheron the border line between the corresponding zones. Therefore, it is possible to obtain aroller bearing which can be practically used, and which can attain a life period that issubstantially equal to that of a bearing having an ideal crowning shape.
