Product Description

Mobil SHC™ Gear Series is a line of exceptional performance, synthetic industrial gear oils designed to provide outstanding protection of gears ａnd bearings, extended oil life even under extreme conditions, helping to enable problem-free operation of equipment ａnd 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 high viscosity index of these oils deliver less change in viscosity with changes in temperature, enabling wider operating temperature range ａnd improved low temperature startup. Mobil SHC Gear Series lubricants contain an advanced proprietary additive system designed to provide excellent protection against conventional wear modes such as scuffing as well as a high level of resistance against micropitting fatigue. In addition, compared to conventional gear oil chemistries, it offers the potential for improved lubrication of gearbox rolling element bearings. Mobil SHC Gear Series products offer outstanding rust ａnd corrosion protection relative to conventional gear oils, even in the presence of seawater contamination. They show no tendency to plug fine filters even when wet ａnd have excellent compatibility with ferrous ａnd non-ferrous metals even at elevated temperatures. Mobil SHC Gear Series also exhibit outstanding compatibility with elastomers in static seal tests. They have outstanding EP properties that provide protection even under shock load conditions. The synthetic base stocks used in Mobil SHC Gear Series oils 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 can help improve gear efficiency.

Mobil SHC Gear lubricants are recommended for enclosed industrial gear drives including steel-on-steel spur, helical, ａnd bevel gears. They are especially recommended for applications that may be subject to micropitting: especially heavily loaded gearboxes with surface-hardened tooth metallurgies. It may also be used in gear applications where extreme low and/or high temperatures are encountered ａnd applications where corrosion may be severe.

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:

Applications

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

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.
