Bearings with a pre-ground raceway

When there is a demand for an exceptionally high degree of running accuracy, SKF recommends mounting the flangeless inner ring of an NNU 49 series bearing onto the shaft and then finish-grinding the inner ring raceway and other shaft diameters in one operation.
For these applications, SKF can supply NNU 49 series bearings with a tapered bore and a finish-grinding allowance on the inner ring raceway (designation suffix VU001). The finish-grinding allowance, which depends on the bore diameter of the inner ring, is listed in table 1.
