NSK NN KR series double row cylindrical roller bearings are components designed to support high radial loads with high rigidity. They are used in applications requiring precision and load capacity, such as machine tool spindles, gearboxes and industrial equipment. At MR Accesorios Industriales we sell this line for the Argentine market, with technical support so you can choose the correct code for your application.

The NN KR series designation is interpreted as follows: the letters NN indicate a double row cylindrical roller bearing, with two rows of rollers that give it greater radial load capacity. The suffix KR indicates a specific execution within the series, generally associated with a design with a machined brass cage and high-precision characteristics. Examples such as NN 3005 KR, NN 3006 KR or NN 3012 KR show the progression of the number that defines the size: the higher the number, the larger the bore diameter and capacity. To identify the exact size, always use the complete code as a guide.

These bearings are used in industries that demand precision and reliability: machine tools, presses, speed reducers, mining and cement equipment, and power transmission systems in steel plants. In Argentina, they are common in the maintenance of main spindles, support rollers and gearboxes where radial loads are high and speeds are moderate. Their double row design allows replacing bulkier configurations, optimizing space in the assembly.

To select the right bearing, take into account the radial load it must support, the rotation speed and the environmental conditions. Sealing is key: if there is contamination, choose variants with additional protection. Lubrication must be the one recommended by the manufacturer, and mounting requires precise alignment and correct adjustment of internal clearance. In high-precision applications, verify the concentricity of the housings. Improper mounting can reduce service life, so it is important to follow proper installation practices.

Regarding equivalences, NSK NN KR series bearings can be interchanged with products from other brands that follow the same dimensional nomenclature. However, tolerances and internal clearance may vary between manufacturers, so it is essential to verify the technical specifications before replacing. If you have the code from another brand, we can help you find the equivalent reference. Interchangeability is not automatic: always confirm the dimensions and operating conditions.
