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 327ºC (620ºF) 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.

Proprietary Additive

N/A 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 1,900ºF (1,038ºC). 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.

LE Modified Timken Test

N/A 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.

Pyroshield vs Competitive Open Gear Lubricants LWI

N/A Conclusion

The graph 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.
