For machine tool spindles and other high-speed, high-precision applications, the NTN NN HS series double row cylindrical roller bearings deliver the rigidity and radial load capacity needed. Their two-row roller design supports demanding operating conditions while maintaining accuracy.
The NN HS series includes part numbers such as NN3005HS, NN3006HS, NN3007HS, NN3008HS, and NN3012HS. In the designation, NN identifies a double row cylindrical roller bearing, the following number is a size code that sets the main dimensions, and the HS suffix denotes a special execution, typically with precision tolerances and high-performance cages. Always confirm the complete part number to ensure the correct size.
These bearings are commonly found in milling machine, grinding machine, and machining center spindles, as well as in power transmission equipment and other high-speed systems. Their ability to handle considerable radial loads makes them suitable for metalworking, automotive, and machine tool manufacturing environments where precision and reliability are critical.
When selecting an NN series bearing, consider radial load, rotation speed, and lubrication conditions. Proper mounting requires precise alignment and strict cleanliness, since the double row needs a correct fit to distribute loads evenly. Grease or oil lubrication must suit the operating temperature and speed. Sealing depends on the environment; in contaminated areas, additional protection is recommended.
Interchangeability with other brands is possible, but tolerances and internal design can differ. Always verify technical specifications and critical dimensions before replacing one bearing with another. For a safe replacement, compare load capacities and service conditions.
