Description
Mobil SHC 629
Exceptional Performance Gear and Bearing Oils
Mobil SHC 629 industrial lubricant is an exceptional performance gear and bearing oil, designed to provide outstanding service in terms of equipment protection, oil life and problem-free operation helping to enable increased customer productivity. This scientifically engineered oil is 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. When used as industrial lubricants, 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. The industrial lubricants of the Mobil SHC 600 Series 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 industrial equipment, not only as high temperature problem solvers, but also because of the other benefits they offer.
Main Applications of Mobil SHC 629
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 gases 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.
Benefits and Features of Mobil SHC 629
Superb high temperature thermal/oxidation resistance
Helps extend equipment high temperature operating capability.
Long oil life helps reduce maintenance costs.
