NTN NN series bearings are double row cylindrical roller bearings designed to withstand high radial loads with high rotational precision. They are used in machine tool spindles, gearboxes and equipment where rigidity and rotational accuracy are critical. MR Accesorios Industriales sells this line as part of its bearing offering for Argentine industry.

The NN series designation reads as follows: the letters NN indicate a double row cylindrical roller bearing; the number that follows, as in NN3005K or NN3012K, indicates the size within the series. The final letter K indicates a tapered bore, which allows mounting with an interference fit on a tapered shaft or with an adapter sleeve. This combination of double row and tapered bore is typical of applications requiring high radial rigidity and good concentricity.

In Argentine industry, these bearings appear in grinding and milling machine spindles, machining heads, speed reducers and transmission equipment working with significant radial loads. They are also found in process pumps, compressors and textile machinery, where rotational precision and load capacity are decisive for equipment service life.

To select the correct bearing, take into account the radial load it will withstand, the rotational speed and the intended type of lubrication. The tapered bore of the NN series facilitates mounting with a controlled fit, but requires verifying the concentricity of the shaft and housing. Lubrication can be grease or oil depending on the application; oil is usually used in high-speed spindles. Alignment between shaft and housing is key to avoiding additional stresses.

If you need to replace a bearing from another brand, the most practical approach is to compare the complete designation: series, size number and K suffix. Equivalences between manufacturers are based on those dimensional and functional characteristics, not on the code alone. So when you request an alternative, provide the exact code shown on the part or in the drawing, and MR will indicate the compatible option.

To request a quote for any NN series bearing, message us on WhatsApp with the complete code (for example, NN3008K) or with the dimensions and characteristics you need. At MR Accesorios Industriales we respond shortly with the corresponding quote. If you can't find the exact variant, send us the model anyway and we'll help you work it out.
