PROBLEM TO BE SOLVED: To obtain accuracy of measurement suitable for mass production and reduce labor for running-in operation of various rotary machines such as assembled gear boxes. SOLUTION: A gap 13 exists between a large diameter side end surface and an inner side surface 7a of a large flange 7 under the state that a small diameter side end surface of a conical roller bearing 3 abuts against an inner side surface 6a of a small flange 6. A minimum value of a measurement ΔL of the gap 13 is not greater than 0.3mm. At the same time, difference between a maximum value and the minimum value of a plural of existing lengths L of the conical rollers 3 is not greater than 0.15mm. |
