SKF-SNFA super-precision bearings in the N 10 series can accommodate shaft diameters ranging from 40 to 80 mm. The bearings are available with a tapered bore only and are manufactured to two tolerance classes. To accommodate increased operational speeds, the bearings are available in a hybrid variant.
The bearing overall dimensions are in accordance with ISO Dimension Series 10 and have a low cross sectional height. They are able to accommodate relatively large diameter shafts to provide the necessary system rigidity within a relatively small bearing envelope. When compared to a set of angular contact ball bearings with the same load carrying capacity and the same degree of rigidity, an N 10 series bearing requires a much smaller radial space. This enables compact spindle bearing arrangements.
