Advanced Wind Turbine Gear Lubricant

Product Description

MOBIL SHC GEAR 320 WT advanced wind turbine gear lubricant is a fully synthetic industrial gear lubricant designed to provide optimum equipment protection of wind turbine gear boxes and Lubricant life even under extreme conditions. ExxonMobil's next generation polyalphaolefin (PAO) technology has been selected for its exceptional oxidation resistance and thermal properties. This exclusive synthetic base fluid is the foundation for a novel, balanced gear oil formulation, which delivers benefits in micropitting, viscosity index, air release, and low temperature flow characteristics versus other synthetic gear oils.

MOBIL SHC GEAR 320 WT advanced wind turbine gear lubricant contains advanced, scientifically engineered and balanced proprietary additive technology designed to provide excellent protection against conventional wear modes such as scuffing but also provides a high level of resistance against micropitting fatigue. In addition, compared to conventional gear oil chemistries, it offers the potential for improved lubrication of gearbox rolling element bearings. MOBIL SHC GEAR 320 WT advanced wind turbine gear lubricant offers outstanding rust and corrosion protection versus conventional gear oils. MOBIL SHC GEAR 320 WT shows no tendency to plug fine filters even when wet and has excellent compatibility with ferrous and non-ferrous metals, even at elevated temperatures.
MOBIL SHC GEAR 320 WT advanced wind turbine gear lubricant is recommended for lubrication of the main gear box in wind turbine power generation systems. It is especially recommended for applications that may be 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 and applications where corrosion may be severe.


Features and Benefits

Mobil SHC synthetic lubricants are recognized and appreciated around the world for innovation and outstanding performance. These molecular design PAO synthetic products, pioneered by our research scientists, symbolize the continuing commitment to using advanced technology to provide outstanding products. A key factor in the development of MOBIL SHC GEAR 320 WT advanced wind turbine gear lubricant was the frequent exchange of information between our scientists and application specialists with key wind turbine, gearbox, and bearing Original Equipment Manufacturers (OEMs) to ensure that this next-generation product offering will provide exceptional performance with the rapidly evolving gearbox designs for wind turbines.  Our field demonstration work with equipment builders will help to confirm the results from our own laboratory tests showing the exceptional performance of the MOBIL SHC GEAR 320 WT advanced wind turbine gear lubricant. This cooperative work will demonstrate the all-round balanced performance benefits for the next-generation MOBIL SHC GEAR 320 WT advanced wind turbine gear lubricant, including a wide temperature range of application.  To address the issue of micropitting gear wear, our product formulation scientists designed a proprietary combination of additives which would resist traditional gear wear mechanisms as well as protecting against micropitting. Our formulators chose exclusive, next-generation PAO synthetic base oils and utilized a novel blending approach to deliver benefits in micropitting, viscosity index, air release, and low temperature flow characteristics, as well as the balance of the performance features. MOBIL SHC GEAR 320 WT advanced wind turbine gear lubricant offers the following benefits:


Advantages and Potential Benefits

Superb protection from micropitting fatigue wear as well as high resistance to traditional scuffing wear

Helps extend gear and bearing life in enclosed gear drives operating under extreme conditions of load, speed and temperature

Helps reduce unplanned downtime; less maintenance - especially critical for difficult to access gearboxes.

Excellent resistance to degradation at high temperatures

Extended oil life and drain intervals help reduce oil consumption and manpower costs

Low traction PAO base stocks for improved gear efficiency

Helps reduce energy consumption and lower operating temperatures

High viscosity index equating to reduced viscosity change with temperature

Ability to operate at both high and low temperatures: especially critical in remote applications with no oil cooling or heating

Excellent resistance to rust and corrosion and very good demulsibility

Smooth, trouble-free operation at high temperatures or in applications subject to water contamination

Excellent compatibility with soft metals

No filter plugging, even in presence of water

Less filter changes and reduced maintenance costs

Excellent compatibility with common gearbox materials of construction and with mineral-based gear oils

Easy changeover from mineral products



Application Considerations: While Mobil SHC Gear 320 WT is compatible with mineral oil-based products, admixture may detract from their performance. Consequently it is recommended that before changing a system to Mobil SHC Gear 320 WT, it should be thoroughly cleaned out and flushed to achieve the maximum performance benefits.

MOBIL SHC GEAR 320 WT advanced wind turbine gear lubricant is designed to provide optimum equipment protection and oil life even under extreme conditions. It is especially formulated to resist micropitting of modern, case hardened gearing and can operate in both high and low temperature environments. Typical applications include:

  • Wind turbines, especially highly loaded and shock loaded units, remotely located units and extreme temperature environments
  • Auxiliary gearboxes in wind turbines, such as gearmotors for pitch and yaw drives
