Advanced Wind Turbine Gear Lubricant

  • Safety Data Sheets (SDS)
  • Product Data Sheets (PDS)

Our Mobil SHC™ Gear 320 WT advanced wind turbine gear lubricant is a fully synthetic gear lubricant designed to protect wind turbine gearboxes operating under extreme conditions, such as extremely low or high temperatures and corrosive environments.

This synthetic wind turbine gearbox oil is formulated to provide excellent protection against conventional wear modes such as scuffing, while also providing a high level of resistance against micropitting fatigue.

Mobil SHC Gear 320 WT wind turbine lubrication can: 

  • Maximize equipment productivity by minimizing unscheduled downtime and maintenance
  • Extend gear and bearing life under high-stress operating conditions
  • Extend oil life

Minimizes downtime with

long drain intervals
power energy saving

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:

FeaturesAdvantages and Potential Benefits
Superb protection from micropitting fatigue wear as well as high resistance to traditional scuffing wearHelps 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 temperaturesExtended oil life and drain intervals help reduce oil consumption and manpower costs
Low traction PAO base stocks for improved gear efficiencyHelps reduce energy consumption and lower operating temperatures
High viscosity index equating to reduced viscosity change with temperatureAbility 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 demulsibilitySmooth, 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 waterLess filter changes and reduced maintenance costs
Excellent compatibility with common gearbox materials of construction and with mineral-based gear oilsEasy changeover from mineral products

 

Applications

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
