RKB NN series cylindrical roller bearings are double-row units built to handle high radial loads where rigidity and precision matter. They are commonly found in heavy industrial machinery that runs continuously under demanding conditions. MR Industrial Accessories LLC supplies these bearings in a range of sizes to customers across the United States and Latin America.
The NN prefix in the designation identifies a double-row cylindrical roller bearing. The number that follows, such as in NN 30/500 or NN 30/600, relates to the bore diameter in millimeters. With the 30/ format, the bore is 500 mm, 600 mm, and so on. This type of coding is typical of large bearings used in heavy-duty equipment.
Typical industries include steel, cement, mining, and heavy machinery manufacturing. These bearings are often found in rolling mills, mills, presses, and power transmission equipment. Their capacity for high radial loads and their rigidity suit assemblies that require precision and durability.
When selecting a bearing, consider the radial load, operating speed, and environmental conditions. Proper lubrication and precise alignment during mounting are essential. Sealing depends on the level of contamination; in dirty environments, additional protection is recommended. The internal clearance must be correct to prevent overheating.
RKB NN series bearings can be interchanged with other brands that use the same nomenclature and dimensions. Always verify tolerances and internal clearance for compatibility. If you are unsure, our team can help you choose.
