NSK NN series cylindrical roller bearings with the KRKR suffix are double-row bearings designed to withstand high radial loads with high rigidity and rotational precision. They are used in machine tool spindles, grinding machine heads and equipment where dimensional accuracy is critical. MR Accesorios Industriales sells this line for the Argentine industrial market, with technical advice to select the right execution for the application.

The NN KRKR series designation is interpreted as follows: the letters NN indicate a double-row cylindrical roller bearing, with two rows of rollers and a cage. The KRKR suffix defines specific design features of this execution, such as cage type, internal clearance and surface treatment. Examples in the series include NN 3030 KRKR, NN 3032 KRKR and NN 3034 KRKR, where the numbers refer to the bore diameter. To identify a specific size, the complete code is the reference MR quotes.

These bearings are used in main spindles of lathes, milling machines and grinding machines, where high radial rigidity and load capacity are required. They are also found in boring machine heads, transmission shafts of precision machines and measuring equipment. In Argentina, they are common in the metalworking, automotive and machine tool industries, where accuracy and repeatability are key factors for machining quality.

To select an NN KRKR bearing, take into account the radial load, rotational speed and lubrication conditions. The double row allows higher loads than a single-row arrangement, but requires precise alignment of the shaft and housing. Mounting must be done with suitable tools, avoiding blows that damage the raceways. Lubrication can be grease or oil, depending on the operating regime, and sealing will depend on the environment: in the presence of contaminants, additional protections should be evaluated.

Regarding equivalences, NSK NN series bearings can be interchanged with references from other brands that follow the same dimensional and execution nomenclature. However, tolerances and internal clearance may vary between manufacturers, so it is essential to verify compatibility before replacing. If the customer brings a code from another brand or an unidentified part, MR can indicate the compatible alternative or quote the exact size needed.

To request a quote for an NSK NN KRKR series bearing, send the complete code via WhatsApp to MR Accesorios Industriales. With the exact reference, we will quote you promptly. If you need assistance identifying the designation, our technical team can help you based on the shaft or housing dimensions. MR sells this line with the backing of more than 80 years in the Argentine industrial market.
