Excellent film strength and extreme pressure properties

  • Extends gearbox life and provides reliable operation in haul truck service
  • Reduces likelihood of seizure, scuffing or spalling of gear teeth under high load conditions

Wide range of extreme service temperature

  • Synthetic formulation and high viscosity index provide efficient lubrication over a wide temperature range and protection in extreme temperature conditions

ENDURATEX Synthetic OHV 680 is approved against the General Electric D50E35E specification for use in the lubrication of both DC and AC motorized wheel gearbox applications in off-highway haul trucks. It is also designed for industrial gearboxes operated under heavy duty conditions such as heavy loading, slow speed, shock loads and in wide extremes of temperature.

Recommended applications for this product include:

  • All types of enclosed gear drives
  • Industrial, heavy duty gear applications with extreme service conditions
  • Bearings, including plain, rolling elements and anti-friction types
