摘要： A rolling bearing includes an outer raceway, an inner raceway, a plurality of rolling elements interposed between the outer raceway and the inner raceway, and a cage for holding the rolling elements away from each other at the same interval in a rolling direction of the rolling elements, the cage including a first layer subjected to a surface treatment of at least one of carbonitriding, phosphating, sulfonitriding and gas soft nitfriding, and a second layer formed of at least one of PTFE, MoS.sub.2, WS.sub.2, Ag and Sn when the first layer includes a treated surface subjected to the surface treatment of phosphating. The rolling bearing can stabilize the attitude of the rolling elements and retain the ease of grinding them. At the same time, the dynamic torque of the rolling elements can be minimized while insuring to prevent the rolling elements from falling away from the cage.

摘要： A rolling bearing fixing device includes at least one bearing having mutually rotatable inner and outer rings, a housing having at least one fitting hole into which the bearing is fitted and a bolt insertion hole, a pair of fixing plates having at least one large-diameter hole and a bolt insertion hole; and a bolt inserted from one axial end into the bolt insertion hole of one fixing plate, the bolt insertion hole of the housing, and the bolt insertion hole of the other fixing plate, and connects the housing with the pair of fixing plates. Both axial end parts of the outer ring are held by the pair of fixing plates in the axial direction, the inner ring is positioned further inwardly of the large-diameter hole of the fixing plates in the radial direction and the inner ring is rotatable with respect to the fixing plates.

摘要： A radial needle bearing includes an outer ring having a race track formed on the inner surface thereof and inward flanges at both ends thereof, a retainer with a plural number of pockets, rotatably located within the outer ring, a seal ring located between the end face of the retainer and inside the inward flange, the seal ring functioning to impede the flow of a lubricating oil flowing in the axial direction within the outer ring, and a plural number of needles rotatably held within each of the pockets. The radial needle bearing is improved in that the outer diameter of the retainer is slightly smaller than the diameter of the race track, and the inner diameter of the retainer is slightly larger than the inscribed circle of the plural number of needles.
