<P>PROBLEM TO BE SOLVED: To provide a rolling bearing capable of properly maintaining lubrication between a guide object face of a cage and a guiding face of a guide member, and actively suppressing wear at a part particularly liable to cause the wear. <P>SOLUTION: This rolling bearing 10 includes an outside spacer 15 arranged adjacently to an outer ring 11, wherein the outside spacer 15 is formed with a guiding face 21 slidably opposed to a guide object face 22 of a cage 14. The guiding face 21 is formed with an annular groove 31 to which a discharge port 17c1 of a flow path 17c for oil air formed in the outside spacer 15 opens. A sidewall surface 31a1 on the axial inside of the annular groove 31 guides compressed air discharged from the discharge port 17c1 toward the axial inside. <P>COPYRIGHT: (C)2013,JPO&INPIT |
