The NNU series double row cylindrical roller bearing, with the KRKR suffix, is a component designed to withstand high radial loads and considerable speeds. Its two-row roller construction offers high rigidity and load capacity, making it suitable for demanding industrial applications. MR Accesorios Industriales sells this NSK series in Buenos Aires, Argentina, and advises you on selecting the correct size for your equipment.

The designation of the NNU series is interpreted as follows: the letters NNU indicate a double row cylindrical roller bearing with a flangeless inner ring and a flanged outer ring. The KRKR suffix indicates a design with a machined brass cage, roller-centered, and a special heat stabilization treatment. The examples NNU 4930 KRKR, NNU 4932 KRKR and NNU 4934 KRKR show how the size varies according to the number that follows the letters. This nomenclature allows you to quickly identify the main characteristics.

These bearings are used in industries such as steel, cement, mining and machine tools, where high radial load capacities and rigidity are required. In Argentina, they are common in gearboxes, rolling mills, mills, presses and power transmission equipment. Their double row design makes them suitable for supporting combined loads and moments, although their specialty is pure radial loads. MR Accesorios Industriales sells them to supply these sectors.

To select the right bearing, take into account the radial load, the rotation speed and the environmental conditions. The KRKR suffix indicates a brass cage, which tolerates high temperatures and shock loads better than polyamide cages. Mounting requires precise alignment and adequate lubrication, either with grease or oil, depending on the application. Check the internal clearance and the fit on the shaft and in the housing to avoid deformation. Incorrect mounting can reduce the service life of the bearing.

As for equivalents, NSK NNU series bearings can be interchanged with those of other brands that follow the same international nomenclature, such as SKF, FAG or NTN, as long as the dimensions and internal design match. It is essential to verify the complete part number and the tolerances. If you have doubts, ask us with the part number of the original part and we will tell you the compatible alternative. MR Accesorios Industriales helps you find the right replacement.
