Testing center

Our French test center guarantees the reliability of our rotary seals

In order to always better secure its customers with reliable and robust rotating sealing components, France Joint has a test center made up of different test benches allowing it to carry out numerous endurance tests.


Test benches for rotary seals

Our benches allow the realization of many tests:
  • Fluid endurance test (10 seals simultaneously)
  • Pollution endurance test (5 seals simultaneously)
  • Cold start test
  • Cold performance test
  • Friction torque measurement
  • Air pressure leak test
  • Measurement of seal assembly and disassembly forces
  • Measurement of the radial force of seals
  • Measurement of the tension at the elongation of the springs
  • etc...


Our test benches have been the subject of tailor-made developments, thus offering our customers many possibilities:
  • Trial - rotating shaft (rotating hub under development)
  • Size from 20 to 250 mm
  • Pressure up to 50 bar
  • Vacuum down to -1 bar
  • Temperature ranging from -50°C to +200°C
  • Speed ​​up to 15,000 rpm in both directions
  • Possible fluids possible (oils, greases, pressurized air, etc.)
  • Shaft run-out management
  • Management of coaxiality defects between the shaft and the housing
  • Axial play management
  • Multiple built-in cameras
  • Multiple thermal sensors
  • Pollution motion system according to requirements
  • Possibility of integrating leak measurement tracers
  • etc...
