  • Ball Bearings ABEC Standard Tolerances Data -

    This tolerance ensures the bearing inner ring surface is close enough to a right angle with the inner ring face. Tolerance figures for face runout/bore are only given for bearings of P5 and P4 precision grades. All points on one circle of the inner ring bore close to the face are measured during one revolution while the outer ring is stationary.
