Mobil SHC™ Gear 460 WT
Advanced Wind Turbine Gear Lubricant
Mobil SHC™ Gear 460 WT advanced wind turbine gear lubricant is a fully synthetic industrial gear lubricant designed to provide optimum equipment protection for wind turbine gearboxes and extended 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 this 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 460 WT advanced wind turbine gear lubricant contains step-out, scientifically engineered proprietary additive technology designed to provide balanced performance in all areas. In particular, Mobil SHC Gear 460 WT offers a high level of resistance against micropitting fatigue and outstanding rust and corrosion protection.

Features and Benefits
Mobil SHC synthetic lubricants are recognized and appreciated around the world for innovation and outstanding performance. Mobil SHC Gear 460 WT advanced wind turbine gear lubricant was developed in close relation with key wind turbine, gearbox, and bearing OEMs to ensure exceptional performance in the rapidly evolving wind turbine gearbox designs.
Our scientists designed a proprietary combination of additives that resist traditional gear wear mechanisms, such as scuffing, as well as protect against micropitting with very low tendency for sludge and deposit formation. The exclusive use of next-generation PAO synthetic base oils and utilization of a novel blending approach delivers balanced performance benefits in micropitting, viscosity index, air release, and low temperature flow characteristics.
Mobil SHC Gear 460 WT advanced wind turbine gear lubricant offers the following features and benefits:

Applications
Mobil SHC Gear 460 WT advanced wind turbine gear lubricant is recommended for lubrication of the main gearbox 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. Compared to conventional gear oil chemistries, Mobil SHC Gear 460 WT advanced wind turbine gear lubricant can provide improved lubrication of gearbox rolling element bearings.
Mobil SHC Gear 460 WT has a recommended operating temperature range of -30 0C to 100 0C.
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
Application consideration: while Mobil SHC Gear 460 WT is compatible with mineral oil-based products, it is recommended that systems are thoroughly cleaned out and flushed before switching to Mobil SHC Gear 460 WT to achieve the maximum performance benefits.
