AUTOMOTIVE BEARINGS:
our solutions rise to your challenges

Benefit from the know-how of a supplier, combined with the technical expertise of a developer in integrated technologies for your automotive bearings.

NTN-SNR provides made-to-measure and innovative responses to your most demanding technical needs:

  • constant innovation and improvement of products and procedures
  • reliability and durability: improvement of materials and heat treatment, the fight against pollution and lack of lubrication
  • simplification of assembly processes: optimisation of the means of securing the bearings on your equipment
  • constraints related to a hostile environment: heat treated materials, specific lubricating greases, optimised materials (bearings for engines and accessories)
  • energy performance: reduction of energy expenditure by reducing friction
  • optimisation of overall dimensions and reduction of weight
  • compliance and security

NTN-SNR provides you with a custom solution.

Wheel bearings

With an ideal compromise between rigidity, useful life, and environmental performance, our wheel bearings are characterised by:

  • optimisation of internal geometry and sealing
  • the use of steel with a very high level of cleanliness
  • the use of greases specifically developed with our suppliers

Our third generation of wheel bearings integrate hub and flange functions for a streamlined and effective assembly and precise adjustment of the pre-load.

NTN-SNR can provide you with robust solutions, whatever your areas of application: passenger vehicles, utilities or heavy goods vehicles.

ASB technology® a NTN-SNR patent! Active Sensor Bearing allows the active measurement of the rotary speed of the wheel.

Bearings for hybrid and electric engines

NTN-SNR is committed to manufacturers developing vehicles with high energy and environmental performance, such as the Renault Zoé or the BMWi3:

  • electrically isolated bearing
  • high performance level
  • presence of very low friction joints
  • long lasting greases
  • ceramic rolling elements
  • specific surface treatment
  • integration of multiple sensors (speed, temperature, position)

Bearings and rollers for engines and accessories

NTN-SNR has good technical mastery in this area:

  • respecting quality and security protocols
  • offering powerful fixtures
  • taking account of constraints related to an application environment: heat treated materials, specific lubricating greases, optimised materials

Gearbox bearings

Our gearbox bearings offer innovative solutions:

  • optimal capacity in an imposed reduced space allowing resistance efforts and maximised longevity
  • high reliability in a harsh environment: pollution control of oils using filter elements and special thermal treatments
  • simplified assembly on the shaft and in the housing
  • high energy efficiency, reducing drag torque and CO2 emissions

Whatever the levels of torques encountered on your transmissions, we can provide a wide range of products to meet all types of applications from passenger vehicles through to heavy goods vehicles.

Clutch release bearings

With 16,500 clutch release bearings made by day, NTN-SNR is naturally one of the largest global manufacturers of clutch release bearings:

  • elaborate design
  • demanding manufacturing process (super-finishing and rectification)
  • unique know-how and expertise in sheet metal technology
  • tests on test benches specifically for clutch release bearings
  • continuous optimisation process

Suspension strut bearings

Our strut bearings have been the subject of a technology patent since 2007. They rely on a precise method of measuring spring forces, specific tools for finite element calculations and tests benches. They are characterised by:

  • an improvement in the seal linked to a labyrinth system associated with a mobile seal
  • reduced friction torque compared to standard solutions
  • elimination of swivelling phenomena
  • better rigidity with sheet metal inserts

Constant-Velocity joints

With an annual production of 5 million CV joints and driveshaft assemblies, we equip all types of vehicles, from passenger cars to utility vehicles, including front-wheel drive, rear-wheel drive or four-wheel drive.

Our permanent areas of development:

  • increase the mechanical potential of our transmission systems
  • improve performance in terms of cost and energy performance
  • improvement of acoustic and vibrational comfort
  • reduce mass
  • facilitate implementation in the vehicle

Composite bearings

NTN-SNR can offer you bearings in composite materials for a wide range of automotive applications (wheels, engine, etc.). The weight of the composite bearings and the cost of the function are reduced compared to traditional solutions. NTN-SNR is developing this range in collaboration with NTN Corporation.

 

 

Modules

NTN-SNR is also your partner for the development and industrialisation of mechanical or mechatronic modules, such as actuators, modules allowing the transformation of a circular movement into a transverse movement (or vice versa).
