    • With the size precision suitable for mass production, the time and labor required for running-in of various rotating machine and apparatus such as a gear box with the bearing installed are reduced.A clearance 13 exists between the end face on the larger diameter side and the inner face 7a of the larger flange portion 7 in the state where the end face on the smaller diameter side of the tapered rollers 3 is abutted to the inner face 6a of the smaller flange portion 6. The minimum value of the size .DELTA.L of the clearance 13 is kept up to 0.3 mm. Simultaneously, the difference between the maximum value and the minimum value in the length L of the tapered rollers 3 is kept up to 0.15 mm.
    • 具有适合批量生产的尺寸精度,减少了各种旋转机器的输入所需的时间和劳动力以及安装有轴承的齿轮箱等装置。 在圆锥滚子3的较小直径侧的端面抵接于圆锥滚子3的内表面6a的状态下,在较大直径侧的端面与较大凸缘部7的内表面7a之间存在间隙13 较小的凸缘部分6.间隙13的尺寸DELTA L的最小值保持高达0.3mm。 同时,圆锥滚子3的长度L的最大值与最小值的差保持为0.15mm。
