ExxonMobil introduced its first synthetic oil for wind turbines in 1998 with Mobilgear SHC XMP. Today, the company says, it produces the initial-fill gear oil of choice for seven of the world’s top 12 wind-turbine builders. The Mobil wind-sector product line also includes greases to lubricate bearings and hydraulic oils that help pitch the huge rotor blades.
Besides protecting against micro-pitting and other forms of equipment wear, Mobilgear SHC XMP is said to exceed the performance of traditional oils by extending the interval between oil changes from 18 months to three years or more. SHC XMP doesn’t clog filters, or disable temperature and pressure gauges, as some other oils can. It also lets turbines perform well in extreme ambient temperatures and maintains stability even in the presence of condensation — a common problem in humid climates.
A few wind-turbine lubricants from the company include:
Mobilgear SHC AMP series: This synthetic gear oil for the main gearbox features all-around protection against gear and bearing wear, such as micropitting and scuffing wear. It has excellent foam and air release, good stability in the presence of water contamination, and protects against corrosion.
Mobil SHC 524: This synthetic hydraulic oil features maximum antiwear protection and high shear stability. It functions well over a wide temperature range and resists deposit formation.
Mobilith SHC: These synthetic greases are for the lubrication of main pitch and yaw bearings (460 WT grease) and generator bearings (SHC 100).
