Mobil SHC Gear series
Our Mobil SHC? Gear synthetic gear oils protect industrial gearboxes and help extend oil life in some of the most extreme conditions. They are formulated for efficient lubrication of industrial enclosed gear drives operating under extreme conditions of load, speed and temperature.
Testing indicates these oils significantly reduce energy consumption in many gearboxes ? up to 3.6 percent* versus conventional oil. These synthetic gear oils also:
- Offer excellent compatibility with gearbox metallurgy
- Protect against scuffing and micropitting
- Offer excellent rust and corrosion protection
- Work well in fine filtration, even when wet
Features and Benefits
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:
Features
Advantages and Potential Benefits
Superb protection from micropitting fatigue wear as well as high resistance to traditional scuffing wear
Helps 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 temperatures
Helps extend oil life and drain intervals and reduce oil consumption, which can lower maintenance costs
Low traction
Helps reduce energy consumption and lower operating temperatures
High viscosity index equating to reduced viscosity change with temperature
Ability 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 demulsibility
Helps 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 stability
Helps extend gear and bearing life
Resistence to filter plugging, even in the presence of water
Fewer filter changes; which can help reduce maintenance costs
Excellent seal compatibility
Less contamination and lower potential for oil leakage
Excellent compatibility with common gearbox materials and with mineral-based gear oils
Easy changeover from many mineral products
