Reduction systems are complex and often specifically designed for each market player. They require great expertise in bearing design and adaptability of production resources in order to deliver THE specific bearing perfectly suited to the application, as offered by NTN-SNR.

  • The crossed roller bearings and 4-point contact ball bearings we design guarantee high load resistance and perfectly rigid reduction systems, thereby ensuring the robot's excellent precision of movement even when handling heavy loads. They can also be used in both cycloidal systems and Harmonic-type technology.
     
  • The NTN-SNR range of thin-section bearings is mostly used in cycloidal / planetary reduction gear systems. They allow the size of the bearing to be reduced while maintaining excellent load resistance and rigidity compared with standard ball bearings, which in turn promotes overall density of the reduction system.

Whether for moving a polyarticular robot across various workstations, assembling your cartesian robot or even if you are looking for the right rail/guide combination for your own linear module, NTN-SNR solutions offer many positive benefits:

  • Flexible, bespoke systems tailored to your needs.
  • Reliable, safe equipment thanks to stringent quality requirements.
  • Innovative solutions developed by the dedicated teams in our European centre of expertise.

In addition to the many possibilities for bespoke designs, NTN-SNR also offers wide ranges of standard products bringing many advantages for your systems:

  • Tapered roller bearings: for axial and radial loads with a large load capacity.
  • Ball bearings: one of the widest ranges on the market, including specific technical solutions (Topline, Lubsolid®, MegaohmTM, EMTR range etc.).
  • KIZEI® spherical roller bearings with shields: NTN-SNR's Research and Development department has created an unprecedented solution to increase the service life of spherical roller bearings. They are especially perfect for fitting onto counterweight systems on polyarticular robots.For this application, we can also offer spherical roller bearings greased with Lubsolid®, a great solution for optimized lifetime without any grease leakage. 
  • Cylindrical roller bearings: designed for high radial loads.
  • Needle roller bearings: our range meets 95% of market needs to suit every application.

 

 

A key mechatronics partner in the automotive industry since the invention of the ASB®, NTN-SNR has broadened its activities to encompass industrial applications with a range of sensors:

  • High-resolution absolute angle measurement sensors.
  • Instrumented bearings for controlling electric motors.
  • Fault detection systems for kinetic chain assemblies.

These compact and designed solutions to facilitate integration, offer an effective response to the constraints and needs faced in robotic systems.

Compactness, speed and mobility are the advantages which best describe this innovative system. Currently used for visual inspection applications and point-based greasing operations, it is also the perfect tool for injecting greater flexibility into cartesian or polyarticular robots.

Driven by their ever-increasing use in the electronics industry, the trend towards miniaturised robots has been gaining traction in recent years. This has prompted us to investigate new designs for our crossed roller bearings used in reduction systems, as well as new production methods in order to be able to automate the assembly of smaller rolling elements. Miniaturising complex mechanical systems and remaining competitive are among the challenges the teams at NTN-SNR have been able to successfully meet.
