This invention improves a rolling bearing fitted to a shaft supporting section of a roller to realize an oscillation roller. A rolling bearing to be fitted to one of the shaft supporting sections of a roller comprises a collared inner ring and a collared outer ring and a plurality of cylindrical rolls arranged between the inner ring and the outer ring as rolling members and the transversal distance of the surface of the inner ring and/or that of the surface of the outer ring facing the raceway surfaces of the cylindrical rolls is made greater than the axial length of the cylindrical rolls to make the inner ring and/or the outer ring, whichever appropriate, of the rolling bearing axially movable so as to allow the roller to oscillate. As the roller moves axially, the inner ring, the outer ring or the cylindrical rolls moves axially.
