“Since their introduction, Mobil SHC Gear Series oils have been helping companies in the mining sector 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 motorized 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 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,” Mokan said. “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 the current GE specification.”

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.
