2-3c. Oil jet lubrication

  • This method uses a nozzle to jet oil at a constant pressure (10 to 50N/cm2), and is highly effective in cooling.
  • Suitable for high rotation speed and heavy load.
  • Generally, the nozzle (diameter 0.5 to 2 mm) is located 5 to 10 mm from the side of a bearing. When a large amount of heat is generated, 2 to 4 nozzles should be used.
  • Since a large amount of oil is supplied in the jet lubrication method, old oil should be discharged with an oil pump to prevent excessive residual oil.
  • Required amount of oil: see reference
