<p><P>PROBLEM TO BE SOLVED: To provide a rolling bearing having an internal clearance capable of reducing interference force acting on a retainer, which is applicable to needle roller bearings, cylindrical roller bearings, and other rolling bearings in order to improve durability of their retainers. <P>SOLUTION: The retainer 2 having a pocket shape capable of controlling a movement of a rolling body 1 to at least one side of a radial direction is applicable to the radial rolling bearing. A movable amount Cp which the rolling body 1 is permitted to move to a radial direction in a pocket 6 is set to be greater than a guiding clearance Cg of the retainer 2. The guiding clearance Cg is equal to a clearance in a radial direction between a retainer guide surface 4 of the retainer 2 and a guided surface of the retainer 2. <P>COPYRIGHT: (C)2004,JPO</p> |
