<p><P>PROBLEM TO BE SOLVED: To provide a rolling bearing capable of surely preventing damage caused by smearing between an inner ring raceway face and a rolling element with a comparatively simple structure, in particular, surely preventing skidding of the rolling element caused by revolving skid and autorotating skid, with respect to the rolling bearing used under high speed and light load. <P>SOLUTION: In this rolling bearing for light load high-speed rotation, an oil receiving wall 6 composed of groove walls at one side of a plurality of grooves, is formed by cutting an axial end face of a cage 4 into square grooves at equal intervals, a nozzle 5 of a jet oil feeder is mounted near the oil receiving wall 6, and oil flow is jetted from the nozzle 5 to provide the cage 4 with torque around a rotating shaft. Thus smearing phenomenon is prevented, and a rotation skid state of sliding without rotation at a fixed position on the raceway face of the inner ring 11, is also prevented. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
