PROBLEM TO BE SOLVED: To reduce the number of components of a quadruple tapered roller bearing and to simplify its manufacturing and assembling. SOLUTION: This quadruple tapered roller bearing is constituted by combining two sets of face-to-face duplex tapered roller bearings in series. Internal outer rings having raceway faces of second and third roller rows observed from one axial side are integrally formed, and end faces of a pair of outside outer rings respectively having raceway faces of first and fourth roller rows are respectively butt jointed to the end faces of the inside outer rings.
