Heavy-Duty Synthetic Grease Provides Extreme Protection

Pyroshield Syn Open Gear Grease 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 that require a lubricant with superior wear protection, exceptional load-carrying ability, outstanding tackiness and ease of application at various temperatures. It also works well for applications in which gears experience high point-of-contact temperatures of 327°C (620°F) and above.

A product of advanced lubricant technology providing boundary lubrication, unmatched performance and versatility, Pyroshield® Syn Open Gear Grease is formulated with high-viscosity 100 percent synthetic base oil, a non-melting thickening system and LE’s proprietary heat stable additives. It contains a synergistic mix of Almasol®, LE’s exclusive wear-reducing additive, and a unique combination of extreme pressure additives.

Almasol® solid wear-reducing additive is able to withstand extremely heavy loads, chemical attack and temperatures up to 1,900°F (1,038°C). It is attracted to metal surfaces, forming a microscopic layer but not building on itself or affecting clearances. Almasol minimizes metal-to-metal contact and the resulting friction, heat and wear.

Beneficial Qualities

  • 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)

Available Grade

  • NLGI 2 applied, 2 in use (5182)
  • NLGI 0 applied, 2 in use (5180)
  • Aerosol as applied, 2 in use (5100)

Using Pyroshield 5100 & 5180

  • Use adequate ventilation if used indoors. These lubricants contain a safe, non-chlorinated solvent for improved pumpability and ease of application at low temperatures
  • After application, the solvent evaporates. The resulting lubricant is an NLGI grade 2 grease.
  • 5180 should not be further diluted with solvent, even if partial evaporation has occurred, as the functional characteristics could be altered

Performance Requirements Met or Exceeded

  • 5180: Metso Mineral Grinding

Typical 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
