Product Description

Mobil SHC™ 600 Series lubricants are exceptional performance gear ａnd bearing oils designed to provide outstanding service in terms of equipment protection, oil life ａnd problem-free operation helping to enable increased customer productivity. These scientifically engineered oils are formulated using the latest proprietary ａnd patent pending Mobil SHC technology to provide outstanding ａnd balanced performance in demanding applications at high ａnd low temperatures. Mobil SHC 600 products feature excellent low temperature properties, as well as improved air release performance in the lower viscosity grades. These products are resistant to mechanical shear, even in heavily loaded gear ａnd high shear bearing applications, so that there is virtually no loss of viscosity.

Mobil SHC 600 Series products have low traction coefficients relative to mineral oils which derive from the molecular structure of the base stocks used. This results in low fluid friction in the load zone of non-conforming surfaces such as gears ａnd rolling contact bearings. Low fluid friction produces lower operating temperatures ａnd improved gear efficiency, which translates into reduced power consumption. Mobil SHC 600 Series products have demonstrated up to 3.6% improvement in energy efficiency in controlled laboratory testing(*). Mobil SHC 600 Series formulation also provides excellent resistance to oxidation ａnd deposit formation at elevated temperatures, as well as exceptional resistance to rusting ａnd corrosion, antiwear, demulsibility, foam control ａnd air release properties, ａnd multi-metal compatibility. Mobil SHC 600 Series oils maintain good compatibility with seals ａnd other materials used in equipment normally lubricated with mineral oils.

Mobil SHC 600 Series lubricants are suitable for use in a wide range of equipment, not only as high temperature problem solvers, but also because of the other benefits they offer.

(*) Energy efficiency relates solely to the performance of Mobil SHC 600 when compared to conventional (mineral) reference oils of the same viscosity grade in circulating ａnd gear applications. The technology used allows up to 3.6% efficiency compared to the reference when tested in a worm gearbox under controlled conditions. Efficiency improvements will vary based on operating conditions ａnd application.

Features ａnd Benefits

The Mobil SHC brand of lubricants are recognized ａnd appreciated around the world for their innovation ａnd outstanding performance. These synthetic products, molecularly designed ａnd pioneered by our research scientists, embody the continuing commitment to using advanced technology to provide outstanding lubricant products. The development of Mobil SHC 600 Series was preceded by close contacts between our scientists ａnd application specialists with key Original Equipment Manufacturers (OEMs) to ensure that the products provide exceptional performance in the continually evolving industrial equipment designs.

Our work with key equipment builders has helped confirm the results from our own laboratory ａnd rig tests showing the exceptional performance of Mobil SHC 600 Series lubricants. Not least among the benefits, shown in work with OEMs, is the potential for energy efficiency improvements up to 3.6% relative to mineral oils (*). These benefits are particularly evident in equipment with a high level of mechanical losses, such as high ratio worm gears.

To develop the latest Mobil SHC technology for Mobil SHC 600 Series oils, our product formulation scientists chose ｓelect base oils because of their exceptional thermal/oxidative resistance potential ａnd combined them with a balanced additive system, which complements the inherent benefits of the base oils to provide excellent oil life, deposit control ａnd resistance to thermal/oxidative ａnd chemical degradation. This formulation approach provides low temperature fluidity characteristics exceeding that of many conventional mineral products ａnd is a key benefit for remote, low ambient temperature applications. Mobil SHC 600 Series oils offer the following features ａnd potential benefits:

Applications

While Mobil SHC 600 Series are generally compatible with mineral oil based products, admixture may detract from their performance. Consequently it is recommended that before changing a system to one of Mobil SHC 600 Series products, it should be thoroughly cleaned out ａnd flushed to achieve the maximum performance benefits. Mobil SHC 600 Series oils are compatible with most NBR, FKM ａnd most other elastomeric seal materials that are used with mineral oils. There is the potential for substantial variations in the elastomers. For best results, consult your equipment supplier, seal manufacturer, or your local company representative to verify compatibility.

Mobil SHC 600 Series lubricants are recommended for use in a wide variety of gear ａnd bearing applications where high or low temperatures are encountered or where operating temperatures or bulk oil temperatures are such that conventional lubricants give unsatisfactory life, or where improved efficiency is desired. They are particularly effective in applications where the maintenance costs of component replacement, system cleaning ａnd lubricant changes are high. Specific applications require selection of the appropriate viscosity grade ａnd include:

• Filled for life gearboxes, especially high ratio/ low-efficiency worm gears
• Remotely located gearboxes, where oil change-out is difficult
• Low temperature applications, such as ski lifts where seasonal oil changes can be avoided
• Mixer roll bearings ａnd roll neck bearings where high temperatures are encountered
• Plastic calenders
• Severe centrifuge applications, including marine centrifuges
• Railroad A/C Traction Drives
• Mobil SHC 626, 627, 629 ａnd 630 are suitable for Oil Flooded Rotary Screw Compressors compressing natural gas, field gas gathering, CO2 ａnd other process gasses used in the natural gas industry
• Mobil SHC 629, 630, 632, 634, 636, ａnd 639 are approved by Siemens AG for use in Flender gearboxes
