For machine tool spindles, grinding heads, and other setups where rotational accuracy and rigidity matter, the NTN NN series of double row cylindrical roller bearings is built to handle high radial loads. MR Industrial Accessories supplies this precision line to maintenance and purchasing teams across the United States and Latin America.
Decoding an NN part number helps you confirm you are ordering the right bearing. The NN prefix signals a double row cylindrical roller design. The two digits that follow represent the diameter series, and the next two are the size code. In NN3013HST6K, for instance, 30 is the diameter series and 13 is the size code. The HST6K suffix points to a high-precision variant. If any part of the code is unclear, our team can help interpret it from the full designation.
These bearings are commonly found in lathe spindles, milling and grinding machines, machining centers, boring heads, rotary tables, and measuring equipment. In metalworking, automotive, and machine tool operations, they are chosen when repeatability and stiffness during machining are priorities.
When selecting a bearing, consider the radial load, operating speed, and lubrication method. The NN series can be grease or oil lubricated; for high-speed use, oil circulation is often recommended. Proper mounting calls for precise alignment and clean conditions, since poor fitting can compromise precision and service life. Also verify internal clearance and sealing to match the working environment.
NTN NN series bearings can be interchanged with other brands that use the same double row nomenclature. If you have a code from another manufacturer or an unidentified part, share the details and we will identify a compatible equivalent. Because interchangeability depends on dimensions and tolerances, always confirm with our technical team before substituting.
