Applications
Mobil SHC Gear 320 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 320 WT advanced wind turbine gear lubricant can provide improved lubrication of gearbox rolling element bearings.
Mobil SHC Gear 320 WT has a recommended operating temperature range of -35 ºC to 100 ºC.
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 320 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 320 WT to achieve the maximum performance benefits.
