NC | One of the Best Lubricants For Open Gears

Gear Shield® NC

When it comes to best girth gear grease Petron is the world leader in lubricants for open gear drives on stationary rotating machinery. Gear Shield® is a high-viscosity lubricant for open gears that provides superior separation of gear teeth in the heaviest loaded zone of gear tooth mesh. Rich in high-viscosity base fluid combined with E.P. and oxidation-resistant additives further enhancing this protection capability. Readily pump able for good lubrication distribution and easily drainable. Petron Gear Shield® is a choice for:  mills and kilns in mineral processing, power generation, windmills, steel, and cement industries. 

Petron Gear Shield Lubricants for Open Gears offers the following benefits:

  1. Restores high viscosity grease film strength on pinion and girth gear.

  2. Eliminates lubricant film rupture.

  3. Exceeds the OEM recommended Lube Film minimum Thickness requirements.

  4. Reduced wear longer life of gears, so lesser maintenance.

Lubricant build-up eliminated through Gear Shield superior drainage capability.
Lubricant build-up increased exposure of gear to air-borne contaminants.
No lubricant build-up on gear teeths.

C. Elimination of Lube Film Rupture - Restoration of Lubricant Film Strength

  1. Lubricant film rupture eliminated.

  2. High viscosity Lubricant Film strength restored on pinion and girth gear.

  3. The Gear Shield exceeded the OEM recommended Lube Film minimum Thickness requirements.

  4. Lubricant Lambda (lubricant film thickness) exceeds AGMA recommended standard of four (4) or greater.

For above listed gear grease types and their proof of performance to find why Petron Gear Shield is the best grease for metal gears due to lower consumption hence reduced lubricant cost & inventory, easy (without buildup & clogging) drainage establishment and others benefits.
