ENDURATEX™ Synthetic EP Gear Oils


ENDURATEX Synthetic EP gear lubricants are premium performance, extreme pressure lubricants designed for enclosed industrial gears and bearings operating under severe load conditions and in wide extremes of temperature.

ENDURATEX Synthetic EP is formulated using synthetic PAO base oils and specially selected additive technologies to deliver excellent wear properties and outstanding extreme temperature performance for extended component and fluid life. ENDURATEX Synthetic EP enhances gear box efficiency over a wide temperature range and can reduce power consumption.

Features & Benefits

  • Outstanding anti-wear protection

    • Extends equipment life​

    • Designed to protect equipment being operated under tough high load conditions

    • Improves operating reliability over a wide range of gearbox loads

  • Better film strength and extreme pressure properties than a global competitor

    • Extends gear and bearing life​

    • Reduces likelihood of seizure, scuffing or spalling of gear teeth and bearings under high load conditions

  • Synthetic formulation reduces friction

    • Energy efficient over a wide temperature range

  • Excellent extreme temperature performance

    • ENDURATEX Synthetic EP Oils protect your equipment in the most extreme temperature conditions

  • Wider range of service temperature

    • Inherent high Viscosity Index (VI) provides a wider operating temperature range

  • Protects against water damage

    • Provides excellent resistance to rust and copper corrosion​


ENDURATEX Synthetic EP premium performance lubricants are recommended for enclosed industrial gear drives and bearings particularly where they are operated under heavy duty conditions such as heavy loading, slow speed, shock loads and in wide extremes of temperature.

The tough oil film and low coefficient of friction save energy in gearboxes. The high viscosity index of ENDURATEX Synthetic EP oils mean they retain their viscosity at high operating temperatures. This often allows the use of a lower ISO grade than with conventional gear oil, resulting in even greater energy savings.


The ENDURATEX Synthetic EP line is designed to combat high temperature conditions and will run cooler while maintaining exceptional lubricant film strength. For gearboxes that operate outdoors, selected ISO grades of ENDURATEX Synthetic EP oils are capable of operating at temperatures as low as -30°C (-22°F) or below.


When converting a gearbox to ENDURATEX Synthetic EP, it is recommended it be cleaned and flushed first to gain the full benefit of the product. ENDURATEX Synthetic EP oils are compatible with mineral oils, polyalphaolefin lubricants and most seal materials except natural rubber.

The ENDURATEX Synthetic EP oils operate over the temperature range from -30°C (-22°F) to 121°C (250°F).


ENDURATEX Synthetic EP oils are designed to meet the following OEM standards:

  • DIN 51517-3-August 2011

  • Approval for Flender Gear Units

  • Eickhoff Gear

  • Jahnel Kestermann

  • AIST 224 (formerly US Steel 224)

  • AGMA 9005-E02 (EP)

  • David Brown S1.53.101 Type E

  • MAG IAS (formerly known as Cincinnati Machine)


ENDURATEX Synthetic EP 150, 220, 320, 460 oils are listed on Flender Gear Units and Geared Motors T7300 Approved Lubricants List and are suitable for use in GE 787/788 drive systems.
