Optigear Synthetic WG Range
Synthetic Industrial Gear Oil
Description
Castrol Optigear™ Synthetic WG range is based on synthetic technology designed to perform in the most challenging of
applications, especially those found in the wind industry. Its high viscosity index coupled with advanced gear oil additives
make it an ideal lubricant for gear boxes where large changes in temperature and humidity can not be controlled.
Application
Optigear Synthetic WG Range has been formulated specifically for use in wind turbine gear box applications but it can be
used for all types of enclosed gears – including heavy and shock-loaded gears and bearings where EP properties are
required. It is suitable for use in gear boxes where micro-pitting resistance is required and for a wide range of
applications in extreme environments including mining and quarrying, marine applications, and paper production.
Optigear Synthetic WG is fully compatible with nitrile, silicone and fluoropolymer seal materials.
Optigear Synthetic WG is classified as follows:

When compared to more conventional gear oils Optigear Synthetic WG has the following advantages:-
Maximum protection of gears against wear and shock loading, including protection against micro-pitting.
Excellent thermal and oxidative stability provides reliable operation and extended operating life when
compared to mineral oil based products.
High corrosion protection for gears.
Inherently high viscosity index makes the product suitable for operations over a wide temperature range.
Good water separation and demulsification characteristics reduce down time through prolonged lubricant life
and increased equipment reliability.Page: 1/2
