NTN spherical roller bearings

NTN spherical roller bearings meet all applications with high radial loads. They accept shaft deflections and misalignment between the shaft and housing.

High-performance bearings
  • load capacity increased by optimisation of the contact surfaces and the quality of steel,
  • sheet metal cages that are processed to increase their resistance and allow better contact with the rollers,
  • increased operating speeds with improved kinematics,
  • dimensional stability up to 200°C due to suitable thermal treatment.
Reduction in the LCC (Life Cycle Cost)
  • improved kinematics results in a lowering of the bearing torque and lowers the operating temperature and power consumed.
  • the useful life is increased thanks to the exceptional endurance of ULTAGE® bearings.
  • the intervals between maintenance periods are significantly lengthened. Less frequent maintenance operations significantly improve the usage rate of the equipment and therefore their productivity.
Resistance to difficult environments
  • shock and vibration: solid cages
  • high levels of vibration: EF800 range
  • pollution: Sealed series
