Synthetic Wind Turbine Gear Oil

Product Description

Mobil SHC Gear 320 WindPower advanced high performance wind turbine gear oil is a synthetic industrial gear lubricant designed to provide optimum equipment protection for wind turbine gearboxes and help maximize lubricant life for smooth wind turbine operations.

Mobil SHC Gear 320 WindPower contains ExxonMobil's metallocene polyalphaolefin (mPAO) synthetic base oil and proprietary additive technology designed to provide balanced performance, in particular, outstanding wear protection provided by increased lubrication film thickness leading to higher load carrying capacity that helps prevent surface fatigue failures.

Additionally, in support of industry focus on White Etching Cracks (WEC) plaguing some wind turbine operations, Mobil SHC Gear 320 WindPower continues our tradition of wind turbine gear oils that are certified to not contribute to oil related effects of White Etching Cracks (WEC) by the world leading certification body DNV .

Furthermore, in combination with Mobil Xtra™ EP WT used as an additive top treat solution enabling Mobil SHC Gear 320 WindPower to retain its performance throughout its lifetime, Mobil SHC Gear 320 WindPower can help protect equipment and maintain excellent performance for the lifetime of the gearbox, helping provide smooth operations in virtually all operating conditions, and help reduce downtime and maintenance costs*. As a result and thanks to a thorough accelerated oil ageing testing program, Mobil SHC Gear 320 WindPower has demonstrated fill-for-life capability and ultimately its suitability of use throughout wind turbine gearbox lifetime of 25 years was certified by DNV.

Mobil SHC Gear 320 WindPower was designed, developed and produced adhering to APQP4Wind standards and best practices to enhance efficiency of wind turbine operators worldwide.

Applications

Mobil SHC Gear 320 WindPower advanced wind turbine gear lubricant is primarily recommended for lubrication of the main gearbox in wind turbines. It is also recommended for applications subject to micropitting, especially heavily loaded gearboxes with surface-hardened tooth metallurgies, which are typically used in wind turbines. It may also be used in gear applications where extreme low and/or high temperatures are encountered.

Typical applications include:

• Wind turbine main gearboxes

• Auxiliary gearboxes in wind turbines, such as gear motors for pitch and yaw drives

Application consideration: while Mobil SHC Gear 320 WindPower is compatible with most widely used wind turbine gear oil products, it is recommended that systems are thoroughly cleaned out and flushed before switching to Mobil SHC Gear 320 WindPower to achieve the maximum performance benefits.
