 Constant velocity joints from NTN are compact, lightweight and high performance.


 

Why choose the range of CV joints from NTN


NTN is innovatively developing a range of constant velocity joints (CVJ) with its teams dedicated to development (product, process).

  • The joints are compact.
    Small in size, they can solve problems of space in the gear box and the wheel hub.
  • The joints are light weight.
    Thanks to the eight ball patented technology from NTN, they limit the weight and consumption of vehicles, as well as CO2 emissions
  • The joints are high performance.
    They contribute to the performance of the vehicles: power transmission, road handling, improved handling and reduction in vibration and noise level in the cabin.

NTN will support you with the technical definition of the product that is best suited to your needs. We will also offer support and focus on the vehicle, in particular to ensure acoustic comfort.

Features of CV joints from NTN


Two wide ranges of CV joints allow the global needs of the automotive market to be met:

For transverse transmissions (half-shafts), the range consists of:

  • Outboard side fixed joints:
    • steering angle of 47° Efficient Ball Joint (EBJ)
    • 50° Value Undercut Joint (VUJ), therefore facilitates manoeuvring the vehicle (parking, travelling around bends, etc.)
  • Sliding joints on the gear box side:
    • Efficient Double offset Joints (EDJ) bearings: recommended for rear application because of their reduced backlash
    • Efficient Tripod Joint ETJ: suitable for all standard applications
    • Premium Tripod Joint (PTJ): perfectly adapted to needs where there is a requirement for low vibration levels, such as in premium or SUV vehicles

For longitudinal transmissions (propeller shafts), the range of CV joints consists of:

  • fixed joints (conventional BJ joints)
  • slip joints with cross groove (LJ joints)
  • slip joints in the tripod (ETJ joints)
  • joints developed for high speed:
    • joints suitable for high speeds and strong mechanical performance (High speed Efficient Ball Joint - HEBJ)
    • crossed track ball joints adapted to high speeds and low backlash (High speed cross groove joint - HLJ)
    • double offset joints adapted to important slide lengths (High speed efficient double offset joint - HEDJ)
    • tripod joints adapted for high speed, very low resistance to sliding and low rises in temperature (High speed efficient tripod - HETJ)
