AEROSPACE BEARINGS
at the service of progress

Aircraft, helicopters, space: our innovative and high-performance aerospace bearings evolve to meet your latest technical developments.

NTN-SNR has been collaborating with the major companies in the aviation industry for more than 50 years. We have contributed to many new programmes, such as the engines on all new single-aisle aircraft (A320neo, B737 MAX…) and AW189 and H175 helicopters.

The evolving technical demands of our customers are the focus of our concerns and our innovations:

Decrease your fuel consumption

NTN-SNR strives to reduce the energy consumption of its customers by producing lighter bearings with ceramic rolling elements for increased speed and reduced rotational torque (thanks in particular to optimised designs).

Improved performance in extreme conditions

As a result of the strength of our R&D, and the resources of a Group of more than 23,000 people, our aerospace bearings can resist the most extreme demands. Our designs are validated on test benches, where we can simulate real flight conditions.

Reduce your maintenance operations

To reduce your maintenance costs, our bearings are made from premium materials and designed using specially developed software.

Opt for innovative mechatronic solutions

Save weight and improve your predictive maintenance. Inspired by our worldwide success in mechatronics in Automotive applications, we offer the same technology and benefits to the Aerospace industry.

Take advantage of our technical support

NTN-SNR is all about products and lots of services! Profit from our technical support, our inspection and refurbishment services, and our customised training.

With our high quality standards we offer tailor-made high-precision bearings for the aerospace market.

Engines

(turbojets, turbofans, turboshafts, turboprops and auxiliary power units)
Working with major engine manufacturers, NTN-SNR provides bearings for:

  • main shafts
  • gearboxes (Inlet, Towershaft, Accessories...)

Helicopters

Their many rotating parts require specific bearings for:

  • turbines
  • gearboxes (main, intermediate and tail)
  • take-off shaft
  • accessory gearboxes
  • rotors (rotor mast, swash plate, blade root….)
  • flying controls

NTN-SNR is No. 1 in Europe for helicopter transmission bearings.

Aircraft

Bearings for the following applications:

  • flying controls
  • accessories: radar, pumps, landing gear, generators…
  • aircraft wheels (additional controls and with "S81” mark certifying the higher quality level)

Space

We supply European space programmes and provide very specific bearings (extreme reliability, cleanliness, lubrication…) for:

  • turbopumps
  • satellites

At NTN-SNR, we have developed high-speed tapered roller bearings to meet the ever greater demands of turbofans thereby helping to reduce both fuel consumption and engine noise levels. We have optimised the internal design of the bearings with our specially developed software. We have developed new surface coatings and heat treatments. The solution was verified on our test bench where realistic flight conditions are reproduced.
Our high-speed tapered roller bearings directly contribute to making Aerospace more environmentally friendly.
