NN series double row cylindrical roller bearings with the HSK suffix are precision components designed for machine tool spindles and applications requiring high rigidity and running accuracy. Their construction with two rows of cylindrical rollers supports high radial loads with minimal deformation, making them suitable for high-speed turning, milling and grinding. MR Accesorios Industriales sells this NTN line in Buenos Aires, Argentina.

The designation of these bearings is interpreted as follows: the letters NN indicate the double row cylindrical roller series; the number that follows, as in NN3005HSK, NN3006HSK or NN3010HSK, indicates the section size. The HSK suffix identifies the execution with a synthetic material cage and special features for high speed and precision. Each code combines series and size; therefore it is advisable to verify the complete number when requesting a quote.

These bearings are used in CNC lathe spindles, machining centers, grinding machines and high-precision milling machines. They also appear in boring heads and in main shafts of machine tools where running accuracy is critical. In Argentine industry, they are common in machining shops, automotive and capital goods, where dimensional repeatability and spindle rigidity define the quality of the finished part.

To select the correct bearing, take into account the radial load, the maximum operating speed and the type of mounting. The NN series can be preloaded and requires an interference fit on the shaft to maintain precision. Sealing and lubrication must be chosen according to the environment: oil for high speeds or grease for sealed applications. Alignment between supports is essential to avoid parasitic loads that reduce service life.

NTN NN HSK bearings can be found under equivalent designations from other brands, although the suffixes and tolerances do not always match. When replacing a part, compare main dimensions, precision class and load capacity. If you have another brand's code or an unidentified sample, at MR Accesorios Industriales we can indicate the compatible alternative or quote the exact size you need.

To move forward with the quote, send us the complete bearing code via WhatsApp, for example NN3012HSK, or the dimensions and features shown on your equipment. We will reply shortly with the information so you can evaluate installing it in your spindle or machine. We also handle inquiries for other precision cylindrical roller bearing series.
