RECOMMENDATIONS FOR USE

Mobil SHC™ 639 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 639 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 639 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 639 products have demonstrated up to 3.6% improvement in energy efficiency in controlled laboratory testing(*).

Mobil SHC 639 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 639 oils maintain good compatibility with seals and other materials used in equipment normally lubricated with mineral oils. Mobil SHC 639 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.

STORAGE

Mobil SHC 639 should be stored under cover in clean, dry conditions and protected from frost. Recommended storage temperature is between 5C and 35C. Use stock in delivery rotation. A shelf life of twenty four months can be anticipated.

What is Mobil SHC 639 and what are its key features?

Mobil SHC 639 is a synthetic industrial gear lubricant specifically designed to meet the needs of heavy-duty industrial gearboxes and other applications where high loads and extreme environments are the norm. Key features of Mobil SHC 639 include excellent resistance to oxidation and thermal degradation, a high viscosity index and good protection against wear and micropitting. It also has good compatibility with various seal materials and provides excellent low-temperature performance.

What are some typical applications of Mobil SHC 639?

Mobil SHC 639 is often used in applications with heavy loads and extreme environments, such as in the mining, steel and paper and pulp industries.
