Product Description
Primetals Gear Oils are high performance lubricants offering outstanding extreme pressure and load carrying properties, specifically designed for use in the enclosed gear drives of Primetals Technologies rolling mill equipment. Primetals Gear Oils are formulated to meet the higher loads of newer gear drive designs by providing extra protection for gears, bearings and seals, as well as protecting gear teeth from micro-pitting wear which can lead to significant gear tooth damage.
Primetals Gear Oils exceed industry requirements for bearing wear protection, offering up to 15 times the wear protection as measured by the industry standard FAG FE 8 test. Their balanced formulation is able to provide maximum wear and corrosion protection while maintaining compatibility with common gearbox seal materials, thereby preventing oil leaks and reducing the ingress of contaminants.
Primetals Gear Oils are recommended for spur, helical and bevel enclosed gears on Primetals Technologies mills with circulating or splash lubrication, operating at bulk oil temperatures up to 100ºC. They are particularly suitable for gears working under heavy or shock loads. Primetals Gear Oils are available in three viscosity grades.
Features and Benefits
Primetals Gear Oils utilize the same technology found in the Mobilgear 600 XP Series gear oils, whose demonstrated performance has made them the primary choice of Primetals Technologies equipment owners worldwide. These premium mineral oil-based lubricants meet the latest gear industry standards and enjoy a reputation for innovation and high performance. Primetals Gear Oils offer the following features and potential benefits:
