LE Almasol High Temperature Lubricant
LE Almasol® High Temperature Lubricant (1250–1251) is a long-lasting, non-melting grease designed for bearings operating in or near heat-generating equipment, where ordinary greases melt and run, leaving critical surfaces unprotected. Formulated with an inorganic thickener, heavy base oil and LE’s proprietary Almasol® solid wear-reducing additive, it stays in place to provide constant lubrication while resisting oxidation and vaporisation – extending lubrication intervals and reducing bearing failures.

KEY FEATURES
| •Heavy base oil and R&O additive formulation ensures extended bearing protection |
| •Won’t melt or run out of bearings |
| •Resists oxidation and vaporisation |
| •DSC time to onset of oxidation (ASTM D5483, 210°C) is almost double that of the nearest competitor tested |
| •1251 (NLGI 1) offers easy pumpability in central lubrication systems |
| •Reduces wear by minimising metal-to-metal friction, even under heavy loads |
| •Protects metal from rust and corrosion |
| •Exhibits excellent mechanical stability |
| •Reduces lubricant consumption and extends lubrication intervals |
| •Reduces downtime associated with bearing failures and frequent regreasing |
APPLICATIONS
| •Asphalt plants |
| •Brick/ceramic kilns |
| •Exhaust fans |
| •Kiln car bearings |
| •Lime kilns |
| •Oven conveyors |
| •Pellet mills |
| •Plastics (e.g. plastic extruders) |
| •Soot blowers |
ADDITIONAL INFORMATION
| Performance Requirements Met or Exceeded | H2 |
| Recommendations | Although formulated with inorganic thickeners, this product contains petroleum oil which, under very high temperatures, can ultimately form carbon and residues as do other greases with petroleum oils. May show high starting torques due to heavy oil. |
| Available Grades | NLGI 2½ (1250), NLGI 1 (1251) |
