Tapered roller bearing for vehicle

摘要

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.
