Pyroshield® Syn Open Gear Grease (5100, 5180, 5182)
Product Description
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.
Beneficial Qualities

Technical Data
Conclusion
The graph above clearly shows the outstanding preventive wear performance that Pyroshield Syn Open Gear Grease provides as compared to competitive products. Load Wear Index (LWI) is a measure of lubricant’s ability to carry a load and minimize wear. The higher the value, the better the lubricant does in preventing wear.
Conclusion
The results of the comparative product testing demonstrate the outstanding load-carrying capacity of Pyroshield Syn Open Gear Grease. It outperformed every competitive product that was tested. Pyroshield had a narrower wear scar and a lower block temperature than all the other lubricants. The test blocks of the competitive products experienced higher temperatures as a result of friction due to poor lubrication. The difference is easily visible in the amount of discoloration of the test blocks.
* An aerosol version of Pyroshield 5182 – Pyroshield 5100 – will have the same physical characteristics as 5182 once in service. The convenient spray cans, which contain no chlorofluorocarbons, are ideal for use with open gears, chains and slides.
Recommendations
- 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).
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.
Typical Applications
- Wire rope
- Chain links
- Pins Bushings
- Cable sheave bushings
- Cables
- Open and closed silent and roller chains
Small, slow-turning gearboxes that require a semifluid lubricant

Applications
Proprietary Additives
LE Almasol Additive
LE’s proprietary additives are used exclusively in LE lubricants. Pyroshield Syn Open Gear Grease contains Almasol.
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.
