Gear Oil

The meshing of metal gears subjects the gear tooth surface to high pressure and impact. Gear oil provides a special coating on the tooth surface to reduce pressure and impact, thus preventing gear wear and seizure. It dissipates the heat of friction generated under various driving conditions like frequent gear changes, continuous high-speed driving, and high-load driving. It also prevents the tooth surface from rusting.

Gear Oil Classification:

• Manual transmission (GL-4)
  Because manual transmissions (MT) contain a synchromesh mechanism, an oil with a low coefficient of dynamic friction is required for this area. A low coefficient of static friction is also required to provide good shift level.
• Differential (GL-5)
  Sulphur-phosphorus-based extreme pressure agents are added to meet the need for high extreme-pressure resistance to counter the impact loads that are applied at high sliding speeds.
• Limited Slip Differential Gear oil
  A clutch is built into the axle, so a high coefficient of dynamic friction is required, while a low coefficient of static friction is required to prevent noise.
