Nengun Direct Japan introduces the ORC409D Single Plate Clutch System.

(high utility clutch series ORC409D: 400ps/55kgfm 

  • ORC's 173 mm diameter small disk is suitable for torque transmission of 100kgfm & above.
  • The ORC systems uses the driving-hub clutch system.
  • The ORC system will improve the number of connecting shafts from 5 to 9 between the clutch cover, plate & flywheel.
  • The ORC improve the mating of the clutch cover with the plates by using a circular disk rather than a pentagon shaped disk. The circular shaped clutch cover & plates distribute the sudden torque generated evenly and will prevent the deformation of the clutch parts.
  • Slits are incorporated to the pressure plate & middle plate to dissipate heat, and protect them from warping due to excessive heat during hard driving.
  • The parts in the ORC clutch system are checked for its reliability & durability for strength in simulation using sophisticated Finite Element Method Analysis computer software.
  • All Ogura flywheel (ORC-FW) are designed specifically for each individual vehicle model. This is done via a thorough study of each engine model by collecting test & research data.
  • All ORC-FW are designed to be strong as well as lightweight using forged using a high grade SCM435 Chrome-molybdenum steel.
  • As per the ORC systems, all ORC-FW are tested for their strength & durability using the Finite Element Method Analysis.
