NN series cylindrical roller bearings are components with high radial load capacity, designed for demanding applications where rigidity and precision are required. Their double-row construction and their ability to withstand combined loads make them ideal for industrial machinery. At MR Accesorios Industriales we sell them in different sizes so you can request a quote for the one you need.
The NN series designation is interpreted as follows: the letters NN indicate that it is a double-row cylindrical roller bearing. The number that follows, as in the examples NN 30/500 or NN 30/600, corresponds to the bore diameter in millimeters. In these cases, the 30/ indicates that the bore diameter is 500 mm, 600 mm, etc. This nomenclature is typical of large-size bearings used in heavy applications.
These bearings are used in industries such as steel, cement, mining and heavy machinery manufacturing. In Argentina, they are common in rolling mills, mills, presses and power transmission equipment. Their ability to withstand high radial loads and their rigidity make them suitable for assemblies where precision and durability are required.
To select the right bearing, take into account the radial load it must withstand, the rotation speed and the environmental conditions. It is essential to ensure adequate lubrication and precise alignment during mounting. Sealing will depend on the contamination present; in dirty environments, additional protection is recommended. The internal clearance must be the appropriate one to avoid overheating.
As for equivalences, RKB NN series bearings can be interchanged with those of other brands that follow the same nomenclature and dimensions. Always verify the tolerances and the internal clearance to guarantee compatibility. If you have doubts, our technical team can advise you.
