Mobilgear SHC XMP Series are high-performance, fully synthetic industrial gear oils based on Mobil's polyalphaolefin (PAO) technology, chosen for its exceptional oxidation resistance, thermal stability, naturally high viscosity index and excellent low-temperature fluidity. Their high viscosity index and low traction coefficient help reduce power consumption in many gear drives, while an advanced proprietary additive system provides excellent protection against scuffing and a high level of resistance to micropitting fatigue, along with improved lubrication of gearbox rolling element bearings.
They are recommended for enclosed industrial gear drives — steel-on-steel spur, helical and bevel gears — especially heavily loaded, surface-hardened gearboxes prone to micropitting, and for applications with extreme low or high temperatures or severe corrosion exposure. Typical uses include wind turbines (particularly shock-loaded, remote or extreme-temperature units), plastic extruder gearboxes, and modern heavily loaded gearboxes in the paper, steel, oil, textile, lumber and cement industries.
Key benefits include outstanding rust and corrosion protection (including salt and acidic water), excellent filter life even when moderately wet, strong compatibility with ferrous and non-ferrous metals at elevated temperatures, and good compatibility with mineral gear oils for easier conversion (though system flushing is recommended before changeover). Grades ISO VG 320 and 460 meet or exceed AGMA 9005-F16 and DIN 51517-3:2009-06.
Applications
Application Considerations: While the Mobilgear SHC XMP 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 Mobilgear SHC XMP Series, it should be thoroughly cleaned out and flushed to achieve the maximum performance benefits. Mobilgear SHC XMP Series supreme performance, fully 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: • Wind turbines, especially highly loaded and shock loaded units, remotely located units and extreme temperature environments • Plastic extruder gearboxes • Modern, highly loaded gearboxes used in the paper, steel, oil, textile, lumber and cement industries where gear protection and optimum oil life are required.
Performance & benefits
The Mobil brand lubricants designated as SHC are recognized and appreciated around the world for innovation and outstanding performance. These molecular design PAO synthetic products, pioneered by our research scientists, symbolize the continuing commitment to using advanced technology to provide outstanding products. A key factor in the development of the Mobilgear SHC XMP Series was the close contacts between our scientists and application specialists with key OEMs to ensure that our product offerings will provide exceptional performance with rapidly evolving industrial gear designs and operation. Our work with equipment builders has helped confirm the results from our own laboratory tests showing the exceptional performance of the Mobilgear SHC XMP Series lubricants. 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 Mobilgear SHC XMP technology, including a wide temperature range of application. To address the issue of micropitting gear wear, our product formulation scientists designed a proprietary combination of additives which would resist traditional gear wear mechanisms as well as protecting against micropitting. Our formulators chose proprietary PAO synthetic base oils to 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 wax-free nature of the synthetic base oil also provides low temperature fluidity characteristics unmatched by mineral products and is a key benefit for remote, low ambient, applications.
