Mobil™ Industrial Lubricants Energy Saving Products: Mobil SHC™ 600 Series and Mobil SHC™ Gear

Mobil SHC Gear Series lubricants are part of the Mobil SHC line of products that are recognized and appreciated around the world for innovation and outstanding performance. These synthetic products, pioneered by our research scientists, symbolize the continuing commitment to using advanced technology to provide lubricants with excellent balanced performance. A key factor in the development of Mobil SHC Gear Series was the close contacts between our scientists and application specialists with key OEMs to ensure that our product offering would provide exceptional performance with rapidly evolving industrial gear designs and operation. Not least among the benefits shown in work with OEMs is the ability to resist micropitting wear which can occur with some highly loaded, case-hardened gearing applications. This cooperative work also demonstrated the all-round balanced performance benefits for the new Mobil SHC Gear technology, including a wide temperature range of application.

To address the issue of micropitting wear, our product formulation scientists designed a proprietary combination of additives which would resist traditional gear wear mechanisms as well as protecting against micropitting. Mobil SHC Gear products provide exceptional oil life and deposit control and resistance to thermal/oxidative and chemical degradation, as well as the balance of the performance features. The patent-pending combination of synthetic base oils also provides exceptional low temperature fluidity characteristics unmatched by conventional mineral oil gear lubricants and is a key benefit for remote, low ambient temperature applications. The Mobil SHC Gear Series lubricants offer the following potential benefits:

FeaturesAdvantages and Potential Benefits
Superb protection from micropitting fatigue wear as well as high resistance to traditional scuffing wearHelps extend gear and bearing life in enclosed gear drives operating under extreme conditions of load, speed and temperature helps reduce unplanned downtime; less maintenance - especially critical for difficult to access gearboxes.
Excellent resistance to degradation at high temperaturesHelps extend oil life and drain intervals and reduce oil consumption, which can lower maintenance costs
Low tractionHelps reduce energy consumption and lower operating temperatures
High viscosity index equating to reduced viscosity change with temperatureAbility to operate at both high and low temperatures: especially critical in remote applications with no oil cooling or heating
Excellent resistance to rust and corrosion and very good demulsibilityHelps to ensure smooth, trouble-free operation at high temperatures or in applications subject to water contamination
Excellent compatibility with a variety of soft metals
Excellent shear stabilityHelps extend gear and bearing life
Resistence to filter plugging, even in the presence of waterFewer filter changes; which can help reduce maintenance costs
Excellent seal compatibilityLess contamination and lower potential for oil leakage
Excellent compatibility with common gearbox materials and with mineral-based gear oilsEasy changeover from many mineral products

Application Considerations: While the Mobil SHC Gear 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 Series, it should be thoroughly cleaned out and flushed to achieve the maximum performance benefits.

Mobil SHC Gear Series exceptional performance, synthetic industrial gear oils are designed to provide optimum equipment protection and oil life even under extreme conditions. They are especially formulated to resist micropitting of modern, case hardened gearing and can operate in both high and low temperature environments. Typical applications include:

• Modern, highly loaded gearboxes used in the paper, steel, oil, textile, lumber and cement industries where gear protection and optimum oil life are required.
• Plastic extruder gearboxes

 
Energy Efficiency

[NOTE: Mobil SHC Gear will ultimately replace Mobilgear SHC Series in the marketplace.]
*The energy efficiency design is a trademark of Exxon Mobil Corporation. Energy efficiency relates solely to the fluid performance when compared with conventional reference oils of the same viscosity grade in gear applications. The technology used allows up to 3.6% efficiency compared with the reference when tested in a worm gearbox under controlled conditions. Efficiency improvements will vary based on operating conditions and applications.
