Typical Applications

  • All differentials and transmissions specifying anEP lubricant (except those requiring pure mineraloil), including:
    • Over-the-road and stop-and-go fleets
    • Off-highway equipment transfer cases,overdrive units, oil-lubricated wheel bearingsand steering gearboxes
    • Limited slip differentials
    • Rockwell and Eaton axles
    • Heavily loaded industrial gearboxes
    • Any gearboxes that have bronze gears, thrustwashers or other parts that require an EP gear oil
    • Worm gearboxes calling for EP gear oils
    • Especially appropriate for machine tools and otherprecision gearing because low wear rate keepsthem within specification longer
