Mobilgrease XHP™ Mine Series
Premium Lithium Complex Grease with Molybdenum Disulfide
The Mobilgrease XHP™ Mine products are specifically designed for the lubrication of extra heavy-duty off-highway and mining equipment. With a complete range of NLGI Grades, this series of lithium complex greases, which contain 5% molybdenum disulfide, can be utilized over a wide range of operating conditions and temperatures to improve productivity. The Mobilgrease XHP Mine series has excellent extreme pressure and anti-wear properties in addition to exceptional staying power, very good water wash-out, water spray-off, and extended service capabilities under harsh operating conditions. These extra heavy-duty service greases exhibit excellent structural stability. They will not corrode steel or copper bearing alloys and are compatible with conventional sealing materials.
Mobilgrease XHP 320 Mine, 321 Mine, and 322 Mine were developed especially for their superior performance in bucket pins, pivot pins, and heavily loaded chassis components. Mobilgrease XHP 100 Mine and 320 Mine are especially suited for heavy equipment central lubrication systems requiring an NLGI 0 Grade grease. Mobilgrease XHP 100 Mine and 320 Mine are recommended by ExxonMobil for use in central lubrication systems found on off-highway and mining equipment. Mobilgrease XHP 100 Mine exhibits good dispensability down to -50°C (-58°F). Mobilgrease XHP 321 Mine is a NLGI 1 Grade with very good low temperature pumpability developed for use in colder temperatures. Mobilgrease XHP 322 Mine is a NLGI 2 Grade for use as a general purpose chassis lube.
Our Mobilgrease XHP™ Mine Series greases are specifically designed to protect off-highway and mining equipment operating under tough conditions including water spray, high sliding/loading and high temperatures.
These premium lithium-complex greases with 5 percent molybdenum disulfide were developed for outstanding performance in bucket pins, pivot pins and heavily-loaded chassis components. They’re formulated to provide:
- Exceptional protection under harsh operating conditions
- Superb resistance to water washout and water spray-off
- Excellent extreme pressure and anti-wear properties
