Precision Spindle Bearings

High precision Double row cylindrical roller bearings correspond to tolerance class SP and are mainly suitable for machine tools application. High precision Double row cylindrical roller bearings are used to give radial support for main spindles. These bearings are available in series NN..30 with cylindrical bore and NN..30 K with tapered bore in which the outer ring is separable and also in NNU..49 with cylindrical as well as tapered bore where the inner ring is separable.
