The Mobil SHC Gear Series is a group of exceptional performance synthetic industrial gear oils designed to provide excellent gear and bearing protection, longer oil life even under severe conditions, and to contribute to trouble-free operation and increased customer productivity. These scientifically engineered synthetic lubricants have been formulated from synthetic base oils that have excellent oxidation and thermal properties and excellent low temperature fluidity. The high viscosity index of these oils guarantees less viscosity change in connection with temperature variations, giving a wider temperature range and easier starting at low temperatures. The oils in the Mobil SHC Gear series contain an advanced patented additive system designed to provide exceptional protection against conventional wear mechanisms, e.g. scratching as well as very good protection against micropitting fatigue. Additionally, compared to the chemistry of conventional gear oils, these oils can improve the lubrication of the gear rolling bearings. Mobil SHC Gear Series products provide excellent rust and corrosion protection compared to conventional gear oils, even when the oil is contaminated with seawater. They show no tendency to clog fine filters, despite high water contents and they have excellent compatibility with ferrous and non-ferrous metals, even at high temperatures. The Mobil SHC Gear series also exhibits excellent compatibility with elastomers in static sealing tests. They have excellent EP properties that provide protection even under shock loading conditions. The synthetic base oils used in the Mobil SHC Gear series have very low traction properties resulting in low fluid friction in the load zone between non-aligned surfaces such as gears and rolling bearings. Reduced fluid friction results in lower operating temperatures which can contribute to improved gear efficiency. Mobil SHC Gear oils are recommended for enclosed industrial gears, including straight and bevel spur gears and steel bevel gears. They are especially recommended for applications that may be subject to micropitting: especially heavily loaded gearboxes with surface-hardened gears. The oils can also be used in gear applications that are exposed to extremely high and/or low temperatures and applications that may be exposed to severe corrosion.
