Manufacturer's description

Mobil SHC™ Gear 320 WindPower is an advanced, high-performance synthetic wind turbine gear oil formulated with ExxonMobil's metallocene polyalphaolefin (mPAO) synthetic base oil and proprietary additive technology. It is engineered to provide optimum equipment protection and maximize lubricant life in wind turbine gearboxes, with increased lubrication film thickness that gives outstanding wear protection and higher load-carrying capacity, helping prevent surface fatigue failures. The oil is certified by DNV to not contribute to oil-related White Etching Crack (WEC) effects, and — when used together with Mobil Xtra™ EP WT top-treat additive — has demonstrated fill-for-life capability through accelerated ageing testing, with DNV certifying its suitability for use throughout a 25-year wind turbine gearbox lifetime. It also offers superb protection against micropitting fatigue wear, high resistance to traditional scuffing, outstanding foam protection even after fine filtration, and a low-sulfur formulation for compatibility with yellow metals and soft coatings. The product was developed in accordance with APQP4Wind standards and best practices. Mobil SHC Gear 320 WindPower is recommended primarily for wind turbine main gearboxes, as well as auxiliary gearboxes such as pitch and yaw drive gear motors, and heavily loaded gearboxes with surface-hardened tooth metallurgies subject to micropitting. It meets or exceeds IEC 61400-4, AGMA 9005-F16 AS, DIN 51517-3 and ISO 12925-1 (L-CKD, L-CKSMP, L-CTPR) requirements, and is non-toxic to aquatic organisms per the GESAMP hazard evaluation procedure.

Applications

• Advanced wind-turbine gear lubricant primarily recommended for lubrication of the main gearbox in wind turbines.
• Recommended for applications subject to micropitting, especially heavily loaded gearboxes with surface-hardened tooth metallurgies typically used in wind turbines.
• May also be used in gear applications where extreme low and/or high temperatures are encountered.
• Wind-turbine main gearboxes.
• Auxiliary gearboxes in wind turbines, such as gear motors for pitch and yaw drives.
• Compatible with most widely used wind-turbine gear-oil products; systems should still be thoroughly cleaned out and flushed before switching, to achieve maximum performance benefits.

Performance & benefits

• Formulated with high-quality synthetic base oils and an advanced, sustainable antioxidant system to help maximize the life of the gear oil to last the lifetime of the gearbox.
• When used in combination with Mobil Xtra EP WT, enables suitability of use throughout the wind-turbine gearbox lifetime, helping optimize wind-turbine uptime and reduce maintenance costs and potential safety incidents.
• Superb protection from micropitting fatigue wear, as well as high resistance to traditional scuffing wear, helping extend gear and bearing life in enclosed gear drives operating under extreme conditions of load, speed and temperature.
• Does not contribute to oil-related effects of White Etching Cracks (WEC), helping reduce unplanned downtime and maintenance from premature bearing failure and gearbox replacement.
• Outstanding foam protection, even after fine filtration, helping reduce the risk of spillage and environmental impact, and reducing turbine trips caused by false oil-level alarms.
