Mobil SHC Gear Series oils meet new GE offhighway certification

first_imgExxonMobil has announced that its Mobil SHC™ Gear Series of synthetic industrial gear oils have been approved for use in General Electric (GE) off-highway vehicle motorised wheel gearbox applications requiring GE’s new gear oil specification, D50E35. Effective January 1, 2016 the new GE D50E35 specification replaces the D50E27 specification for GE drives used in equipment such as construction vehicles and mining haul trucks. The new spec establishes micro pitting protection requirements in addition to scuffing wear resistance and other improvements.“Since their introduction, Mobil SHC Gear Series oils have been helping companies in the mining and construction sectors get more out of their equipment,” said Larry Mokan, Senior Equipment builder Engineer at ExxonMobil Fuels & Lubricants. “Mobil SHC Gear Series synthetic oils meet the stringent new gear oil requirements for GE motorised gear drives with a formulation that delivers outstanding protection in extreme temperature and load conditions while combating micro pitting fatigue wear, rust and corrosion.” The gear oils offer up to 3.6% improved energy efficiency versus conventional oil.The company said that the Mobil SHC Gear Series “represents the company’s continued commitment to developing advanced, high-performance lubricant technologies that can help customers decrease costs and improve the productivity of their operations.” These oils contain an advanced, proprietary additive system designed to protect gears from conventional wear modes, such as scuffing, while offering a high-level of resistance against micro pitting fatigue. In addition, the oils offer the potential for improved lubrication of gearbox rolling element bearings as compared to conventional gear oils.“We began GE D50E35 qualification testing early and met the new requirements shortly after they were published in late 2014. We are confident that owners of GE OHV motorised gearbox drives who choose Mobil SHC Gear oils will also experience the same excellent field performance enjoyed by our customers over the past four years under the current GE specification,” said Mokan. The complete range of viscosities for the Mobil SHC Gear Series, ISO VG 150, 220, 320, 460 and 680, are approved for use under GE Material D50E35, categories A-E.last_img
