Rolling bearing

A method for producing the rolling bearing according to claim,

• wherein the rolling elements are received between the outer race and the inner race;
• wherein at least one end of the opening of the bearing space formed between the outer race and the inner race is covered with the sealing ring made of a resin;
• wherein the sealing ring is provided with the oil flow holes, and the respective oil flow holes are provided with the filters configured to capture foreign substances contained in a lubricating oil;
• wherein the sealing ring comprises the plurality of engaging portions provided on the radially inner surface of the sealing ring in a protruding manner along the circumferential direction thereof;
• wherein the inner race comprises the recesses provided on the outer peripheral surface thereof and engaging with the engaging portions;
• wherein the annular member made of a material softer than that of the sealing ring is fixed to the sealing ring;
• wherein the annular member includes the lip portion which faces the outer race with the gap or comes into contact with the outer race;
• and
• wherein the sealing ring is formed by injection molding, and the gates (g) through which the resin is supplied during the injection molding are disposed in portions of the sealing ring corresponding to the radial directions along which the oil flow holes are not disposed, so that the weld lines generated during the injection molding are formed in the portions of the sealing ring corresponding to the radial directions along which the oil flow holes are not disposed.
