FAG super precision bearings of the NN-AS-K-M-SP series are double-row cylindrical roller bearings designed for machine tools and equipment that demand maximum rotational accuracy. Their construction allows high speeds with high rigidity and low friction. They are used in grinding machine spindles, milling machines and machining centers, where dimensional precision and stable thermal behavior are decisive. MR Accesorios Industriales supplies this line as an official brand, with technical advice to select the appropriate variant according to the application.

The designation of the series is read in blocks. The letters NN indicate a double-row cylindrical roller bearing; the number that follows, as in NN3026 or NN3032, is linked to the section size. The suffixes AS, K, M and SP provide construction and precision characteristics: AS is associated with a design with lubrication groove and holes, K with the machined brass cage, M with the solid cage and SP with the super precision class. Thus, NN30/500-AS-K-M-SP and NN3038-AS-K-M-SP share the same design family.

These bearings are used in grinding machine spindles, milling machines, boring machines and high-speed machining centers. They also appear in measuring heads, precision rotary tables and optical or metrology equipment. In Argentine industry they are found in die-making workshops, automotive plants, machine tool factories and calibration laboratories. Their function is to support the spindle with the least possible deviation, even at high speeds and with combined loads.

To select correctly, consider the maximum speed, the axial and radial load, and the type of lubrication. The series accepts grease or oil lubrication, and in many cases a mounting fit with controlled interference is required. Alignment between supports is critical: it is advisable to verify the concentricity of the housing and the shaft. Sealing will depend on the environment: in the presence of coolant or particles, additional protection is recommended. Internal clearance and preload are defined according to the desired rigidity. Mounting with suitable tools and rigorous cleanliness extends service life.

Regarding equivalences, double-row super precision bearings are interchanged between manufacturers according to dimensions and precision class, but suffixes and tolerances do not always match. To replace a FAG with another brand, compare bore diameter, outer diameter, width, ISO class and cage configuration. It is not advisable to rely only on the part number: two similar designations may differ in preload or lubrication. MR Accesorios Industriales can guide that technical comparison and suggest the alternative that best fits the spindle.

If you need to replace a bearing of this series, send the complete part number via WhatsApp to MR Accesorios Industriales. With the model and the application, the technical team reviews the variant and replies shortly with the quote. You can also inquire about other super precision designs or special bearings for your equipment.
