LE Pyroshield Syn Open Gear Grease
LE Pyroshield® Syn Open Gear Grease (5180) is a heavy-duty synthetic lubricant developed for large unshrouded open gears in the mining, mineral processing and cement industries, and for other severe service applications requiring superior wear protection, exceptional load-carrying ability, outstanding tackiness and ease of application at various temperatures. It also works well where gears experience point-of-contact temperatures of 327°C (620°F) and above. Formulated with high-viscosity 100 percent synthetic base oil, a non-melting thickening system and LE’s heat-stable additives, it contains a synergistic mix of Almasol® and a unique combination of extreme pressure additives.

KEY FEATURES
| •Increases uptime, lengthens equipment life, lowers lubricant consumption and reduces maintenance |
| •Outperforms similar products in wear protection and load-carrying ability – narrower wear scar and lower block temperature than all competitive products in LE Modified Timken testing |
| •Carries a 90-lb Timken OK load |
| •Resists shock loading |
| •Excellent oxidation resistance and rust protection |
| •Reduces noise in large open gears |
| •Clings tenaciously to surfaces and resists removal by water, heat and other severe conditions |
| •Does not thin or run at high temperatures |
| •No dropping point – will not melt |
| •Remains pumpable at low temperatures |
| •Works for open gears and heavily loaded sliding applications |
APPLICATIONS
| •Various applications in the mining and mineral processing industry |
| •Open gears and slides |
| •Ball mill open gears |
| •Kiln open gears |
| •Bar screens |
| •Dipper sticks |
| •Circle rails |
ADDITIONAL INFORMATION
| Performance Requirements Met or Exceeded | Metso Mineral Grinding |
| Switching Recommendation | For best results when switching to Pyroshield Syn Open Gear Grease, first clean the area of application with LE’s Duolec® Industrial Gear Oil (1609). |
| Usage | Use adequate ventilation if used indoors. This lubricant contains a safe, non-chlorinated solvent for improved pumpability and ease of application at low temperatures; after application the solvent evaporates, leaving an NLGI 2 grease. 5180 should not be further diluted with solvent, even if partial evaporation has occurred. |
