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 CO2, 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.

While Mobil SHC 600 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 600 Series, it should be thoroughly cleaned out and flushed to achieve the maximum performance benefits. The Mobil SHC 600 Series oils are compatible with the following seal materials: fluorocarbon, polyacrylate, polyurethane ether, some silicone, ethylene/acrylic, chlorinated polyethylene, polysulfide, and some nitrile rubbers. There is the potential for substantial variations in the elastomers being used today. For best results, consult your equipment supplier, seal manufacturer, or your local Mobil 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 needed. They are particularly effective in applications where the maintenance costs of component replacement, system cleaning and lubricant changes are high. Specific applications 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™ 625*, 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.

 
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.
