SHC 600 lubricant coating gears

Mobil SHC™ 600 Series

Next-generation circulating and gear oils
From heavy loads to extreme temperature variations, industrial gearboxes operate under challenging conditions. Advanced technology Mobil SHC 600 Series synthetic lubricants deliver premium performance even under these conditions to meet the demands of your machinery.

Reduced energy consumption up to 3.6%*
In a gearbox and circulating oil system, the low traction and high viscosity index in Mobil SHC 600 Series oils combine to significantly reduce power consumption—and energy costs—compared with mineral oils. That reduced consumption can translate to an overall reduction of CO, helping you meet emissions regulations.

Already recommended for use in 1,800 applications by more than 500 major equipment builders, Mobil SHC 600 Series lubricants continue to be recognized by OEMs for delivering improvements in key areas while maintaining excellent performance.
 

Mobil SHC™ 600 Performance Profile

Mobil™ Industrial Lubricants Energy Saving Products: Mobil SHC™ 600 Series and Mobil SHC™ Gear

 

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:

FeaturesAdvantages and Potential Benefits
Superb high temperature thermal/oxidation resistanceHelps extend equipment high temperature operating capability
Long oil life, helps reduce maintenance costs
Helps minimize deposits to enable trouble-free operation and long filter life
High Viscosity Index and absence of waxMaintains viscosity and film thickness at high temperatures
Helps enable exceptional low temperature performance, including start-up
Low traction coefficientHelps reduce friction and increase efficiency in sliding mechanisms such as gearing, with potential for reduced power consumption and lower steady-state operating temperatures.
Helps minimize the effects of micro slip in rolling contact bearings to potentially extend rolling-element life
High load carrying capabilityHelps protects equipment and extends life; helps minimize unexpected downtime and extends service periods
Balanced additive combinationProvides excellent performance in terms of rust and corrosion prevention, water separability, foam control and air release performance enabling problem-free operation in a wide range of industrial applications, and reduced operating costs

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 calendars
• 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

 
energy efficiency

  *The energy efficiency design is a trademark of Exxon Mobil Corporation. Energy efficiency relates solely to the fluid performance 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 with the reference when tested in a worm gearbox under controlled conditions. Efficiency improvements will vary based on operating conditions and applications.
