Features ａnd Benefits
Mobilgrease HTR, HTM, HTS ａnd HTF greases are leading members of the Mobilgrease brand of products, which has gained a worldwide reputation for innovation ａnd performance excellence. Mobilgrease HTR, HTM, HTS ａnd HTF grease products are designed by ExxonMobil formulation technologists ａnd backed by our worldwide technical support staff.
Mobilgrease HT products were designed specifically to meet the requirements of customers for heavy-duty products with excellent: resistance to water, high temperature ａnd with cohesive ａnd adhesive properties. These greases offer the following features ａnd potential benefits:
| Features | Advantages ａnd Potential Benefits |
| High EHL viscometrics ａnd selected additives for excellent resistance to wear for heavily loaded components | Less unexpected downtime ａnd reduced equipment replacement costs |
| Excellent ability to seal bearings against water intrusion, ａnd to maintain consistency in the presence of water | Fewer bearing failures caused by water contamination with reduced maintenance ａnd replacement costs |
| Exceptional corrosion resistance | Very good bearing protection for reduced maintenance ａnd operating costs |
| Excellent grease cohesion, adhesion ａnd tackiness at high temperatures ａnd in presence of water spray | Better stay-put properties in tough environments ａnd extended re-lubrication potential |
| Good pumpability at low to moderate temperatures | Can be used in centralised grease distribution systems |
Applications
Mobilgrease HTR is primarily intended to address low temperature pumpability challenges. Mobilgrease HTM provides good pumpability with additional protection against water intrusion. Where an NLGI Grade 2 grease can be used, Mobilgrease HTS provides maximum bearing lubrication performance. Mobilgrease HTF provides fire retardancy for castor ａnd hot strip mill operations.
Mobilgrease HTR, HTM, HTS ａnd HTF greases are designed primarily for the lubrication of bearings, gears, ａnd cams, which require high viscosity base oil. Such heavy-duty applications include:
- Steel mill bearings,
- Off-highway rolling stock
- Surface mining drag lines, excavators, drills ａnd haul trucks
