NN3052-AS-K-M-SP FAG Precision Double Row Cylindrical Roller Bearing with Tapered Bore 260x400x104mm Shields Fatigue load limit Pu 50Cylindrical roller bearings for main spindles are used when the very highest precision is required under very high radial load. Typical areas of application include machine tools and printing machinery. The bearings facilitate bearing arrangements with very high precision, high radial rigidity and very high load carrying capacity. In machine tool building, they provide radial support for the main spindle. These are single or double row cylindrical
