Exceptional Performance Gear Oils for Off-Highway Equipment
Product Description
The Mobil SHC™ Gear OH Series lubricants are exceptional performance heavy-duty gear oils primarily designed to lubricate enclosed gearing as well as plain ａnd rolling element bearings in off-highway equipment subject to shock ａnd heavy loading. They are designed to provide outstanding service in terms of equipment protection, oil life, ａnd problem-free operation helping to enable increased customer productivity. These scientifically engineered synthetic lubricants are formulated from synthetic base fluids that have exceptional oxidation ａnd thermal properties ａnd excellent low temperature fluidity. The combination of a naturally high viscosity index ａnd a unique additive system helps enable these products to provide outstanding performance under severe high ａnd low temperature operating conditions. The nature of the synthetic base fluids also contributes to the products＇ excellent low temperature performance. They deliver outstanding gear scuffing protection in heavily loaded gearboxes. The synthetic base stocks have inherently low traction properties that result in low fluid friction in the load zone of non-conforming surfaces such as gears ａnd rolling element bearings. Reduced fluid friction produces lower operating temperatures ａnd improved gear efficiency. The Mobil SHC Gear OH Series is available in viscosity range from ISO VG 320 to 680, ａnd are the products of choice for key OEMs ａnd customers for demanding off-highway applications.

Features ａnd Benefits
The Mobil SHC Gear OH Series of lubricants is a member of the Mobil SHC brand of products. These scientifically engineered synthetic lubricants symbolize the continuing commitment to using advanced technology to provide outstanding lubricant products. The Mobil SHC Gear OH Series of lubricants provide benefits not possible with mineral stocks, particularly under extreme high ａnd low temperature operating conditions.
Our formulation scientists have used a proprietary additive combination that fortifies the base fluids to provide excellent EP ａnd anti-wear performance that protects equipment, even under heavy load situations. Specific features ａnd potential benefits for the Mobil SHC Gear OH Series of lubricants include:
Features Advantages ａnd Potential Benefits Outstanding load-carrying ａnd antiwear properties Helps extend gear life ａnd reduce maintenance costs High viscosity index Trouble-free operation over a wide temperature range particularly at extremely low temperatures. Low traction properties Helps improve gear efficiency ａnd lower operating temperatures lead to lower operating costs Outstanding thermal/oxidation resistance ａnd long product life Helps reduce lubricant consumption, which can reduce product ａnd change-out costs Light color Helps minimize the need for gear cleaning prior to inspections, which can reduce maintenance costs

Applications
Application Considerations: While the Mobil SHC Gear OH Series are compatible with mineral oil based products, admixture may detract from their performance. Consequently it is recommended that before changing a system to one of the Mobil SHC Gear OH Series, it should be thoroughly cleaned out ａnd flushed to achieve the maximum performance benefits.
Mobil SHC Gear OH Series oils are recommended for many types of enclosed steel-on-steel gear drives. They are suitable for both circulation ａnd splash lubrication systems. Mobil SHC Gear OH Series is available in viscosities from ISO 320 to ISO 680, providing the right lubrication option for low temperature applications where pour points as low as -45°C (-49°F) are required to high temperature applications where operating temperatures of 121ºC (250ºF) are encountered. They are particularly recommended for lubricating gear sets in off-highway applications such as those found in mining, where heavy or shock loads ａnd boundary lubrication conditions may prevail.
