Abstract
By incorporating a pump for sucking and discharging lubricating oil in a tank for storing the lubricating oil on an outside of a rolling bearing, for example, on a spacer for an outer ring in a housing for accommodating the rolling bearing and a nozzle in which an lubricating oil outlet communicating with a discharging port of the pump to supply the lubricating oil discharged from the pump to the rolling bearing is opened in an annular-shaped space between a fixed ring and a rolling ring in the rolling bearing, a cost is reduced by using a general-purpose rolling bearing, and at the same time, external devices and pipes for a lubrication are not required wholly or partially and problems of a noise made by compressed air are eliminated.
