Abstract
A rolling bearing provided with measures to suppress a rise in temperature. The rolling bearing comprises inner and outer races, a plurality of rolling elements 16 interposed between the inner and outer races, and a cage for retaining the rolling elements 16. On the use conditions that the direction of load is stationary to the outer/inner race and rotational with respect to the inner/outer race of the two races, the cage 17 is guided for rotation with outer/inner regions of its pocket surfaces in contact with the rolling elements 16. It is also intended to facilitate satisfactory lubrication by means of grease and to enhance the durability and life of the bearing. For that purpose, a bearing 21 incorporated into a main motor is arranged with both end faces adjoining end members 24 and 25 that have grease pockets 22 and 23 formed therein, respectively. The bearing 21 includes an outer race 27 whose bore surfaces 33 and 34 on its ribs 31 and 32 are flush with the inner peripheries 35 and 36 of the grease pockets 22 and 23 in the end members 24 and 25, respectively.
