Document Type and Number:
WIPO Patent Application WO/2003/060340
Kind Code:
A1
Abstract:
A rolling bearing with suppressed spin sliding between rolling elements and raceway grooves and with low torque realized by reducing rolling resistance. Although the bearing is an one-piece raceway-type, the rolling elements can be assembled easily. Further, the rolling elements even of this type of bearing can be assembled easily in a state where one-piece type raceways and a retainer have been assembled. At the center of an inner raceway groove (3), there is provided a small groove (4) where the rolling elements are turned in raceway groove space after outer and inner raceways and a retainer have been assembled. In a retainer (6), only pocket faces (7b) in one axial direction of pockets (7) are provided, and the faces of the pockets in the other direction are made to be open.
