Spherical Roller Bearings

ULTAGE, a label for exceptional performance in all markets

Able to use the ULTAGE  label, NTN spherical roller bearings offer exceptional performance. By their design and their manufacturing process, they demonstrate reliability and are used as a benchmark on the following markets: 

• Mining and quarrying as well as cement 
• Steel Industry
• Gearboxes
• Wind Energy
• Pulp and Paper Industry
• Rail Transport
• Construction Machines: Construction of Roads, Graders.
• Elevators: the Sealed series with the low noise option is perfectly suited to this application

Bearings that help your production

• 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 200degree 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.
