PROBLEM TO BE SOLVED: To provide a conical roller bearing which reduces rotation torque, and can rotate at a high speed.SOLUTION: A conical roller bearing 1 comprises: an inner ring 2; an outer ring 3; a plurality of conical rollers 4 interposed between the inner ring 2 and the outer ring 3; and a cage 10 having a pocket 14 for accommodating the conical rollers 4. Annular part side faces 11c and 12c which position the cage 10 in the axial direction by end faces 4a and 4b of the conical rollers 4 by slide-contacting with the end faces 4a and 4b of the conical rollers 4 are arranged at annular parts 11 and 12 of the cage. An external side face 13a for positioning the cage 10 in the radiation direction by an outer ring raceway face 3a by slide-contacting with the outer ring raceway face 3a is formed at a columnar part 13 of the cage 10. |
