Mobil SHC Gear Series Oils Meet New GE Gear Oil D50E35 Specification

ExxonMobil has announced that its Mobil SHC™ Gear Series of synthetic industrial gear oils have been approved for use inGeneral Electric (GE) off-highway vehicle motorized wheel gearbox applicationsrequiring GE’s new  gear oil specification, D50E35.

Effective Jan. 1, 2016 the new GE D50E35 specificationreplaces the D50E27 specificationfor GEdrives used in equipment such as construction vehicles and mining haul trucks. The new spec establishes micropitting 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 sectorsget 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 motorized gear driveswith a formulation that delivers outstanding protection in extreme temperature and load conditions while combatingmicropittingfatigue wear, rust and corrosion.”

The Mobil SHC Gear Series representsthe company’s continued commitment to developing advanced, high-performance lubricant technologiesthat canhelp customers decrease costs and improve the productivity of their operations.

These oils contain an advanced, proprietary additive system designed to protectgears from conventional wear modes, such as scuffing,while offering a high-level of resistance against micropitting fatigue. In addition, the oils offer the potential for improved lubrication of gearbox rolling element bearings as compared to conventional gear oils.

“We beganGE 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 motorized 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 thecurrent 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.
