-
Mobil SHC Gear Series lubricants are part of the Mobil SHC line of products recognized globally for innovation and outstanding performance.
-
These synthetic products, pioneered by Mobil's research scientists, symbolize the commitment to advanced technology for excellent balanced performance.
-
A key factor in the development of Mobil SHC Gear Series was the collaboration between scientists, application specialists, and key OEMs to ensure exceptional performance with evolving industrial gear designs and operations.
-
One major benefit demonstrated through work with OEMs is the resistance to micropitting wear, which can occur in some highly loaded, case-hardened gearing applications.
-
This cooperative effort also highlighted the all-round balanced performance benefits of the new Mobil SHC Gear technology, including its wide temperature range of application.
-
To address micropitting wear, product formulation scientists designed a proprietary additive combination that resists traditional gear wear mechanisms and protects against micropitting.
-
Mobil SHC Gear products provide exceptional oil life, deposit control, resistance to thermal/oxidative and chemical degradation, and a balance of performance features.
-
The patent-pending combination of synthetic base oils offers exceptional low-temperature fluidity characteristics, unmatched by conventional mineral oil gear lubricants, making it ideal 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

-
While the Mobil SHC Gear Series are compatible with mineral oil-based products, admixture may detract from their performance.
-
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 specially 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.
-
They are also suitable for plastic extruder gearboxes.
-
Mobil SHC Gear Series ISO VG 150, 220, 320, 460, and 680 are approved under General Electric's (GE) gear oil specification D50E35 for use in off-highway vehicle motorized wheel gearbox applications.
