Mobil SHC 634 High-performance gear & bearing oil ISO VG 460, 20L

Application

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 634 is approved by Siemens AG for use in Flender gearboxes

Specifications & Approvals

• DIN 51517-3:2014-02 (CLP gear oils)
• ISO L-CKD (ISO 12925-1:2018)
• Flender 
• GE D50E32 AC Traction Motor
• SEW-Eurodrive
• AGMA 9005-F16

Features

• Superb high temperature thermal/oxidation resistance 
• High Viscosity Index and absence of wax
• Low traction coefficient
• High load carrying capability
• Balanced additive combination
• Container size: 20l canister
• Also available in: 208l barrel

Advantages and Potential Benefits

• Helps 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
• Maintains viscosity and film thickness at high temperatures
• Helps enable exceptional low temperature performance, including start-up
• Helps 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
• Helps protects equipment and extends life; helps minimize unexpected downtime and extends service periods
• Provides 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

Technical specifications

Product Description Mobil SHC™ 600 Series

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.

Application Notes

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.
