Yueqing H23/H32 series with adapter sleeve http://www.wzlmjx.com/products_view.asp?id=1931 tight sleeve thread thrust ball locking performance adapter sleeve is an annex of the taper, the longest life expectancy is the basic requirement to up-aligning ball to the target, which would ensure the stable operation of the supporting adapter sleeve must meet high-precision job. The four technical accuracy is most important: adapter lining NSK the cone bearing sleeve inner hole radial runout (commonly termed wall thickness difference KD0. Want to high-precision, or axis of rotation centrifugal force generated due to the amount of eccentricity tapered roller vibration, smooth operation, the thickness difference "0" is the ideal state. GB provisions the maximum diameter KD0 6FAG5 size segment is about 1/2 of the maximum clearance of the bearing standard group and C2-level precision clearance value equivalent noise, so GB qualified aligning the roller of tight sets with in the Precision big load FYH bearing support is not enough.
