NAT-3088 Multi-Purpose Open Gear Lubricant

Premium grade para-synthetic, extreme pressure, multi-purpose open gear lubricant for mining equipment — shovels, draglines, and excavators. Contains MoS₂ and solid lubricants with EP weld >800 kg and FZG +13. Meets P&H 520/464 and Bucyrus SD4713 specifications.

Overview

NAT-3088 is a premium grade, extreme pressure, para-synthetic, multi-purpose open gear lubricant designed for use on open gears in mining equipment — shovels, draglines, excavators, stackers, and reclaimers. It can also be used in the lubrication of sleeve-type bushings and slow-moving, heavily loaded bearings, shovel dipper sticks, circle rails and rollers, ball mills, and slow-moving wire ropes.

NAT-3088 is compounded from a select blend of petroleum, resins, and polymeric synthetic base fluids.

NAT-3088 forms an adhesive film that resists "squeeze out," "sling out," and "fling off," allowing the product to cling tenaciously to gears in a vertical orientation.

NAT-3088 contains a synergistic blend of anti-wear and extreme pressure additives, antioxidants, corrosion inhibitors, molybdenum disulfide, and other solid lubricants providing:

  • Excellent anti-wear and extreme pressure protection for heavily loaded open gears, bearings, and bushings.
  • Extended component life and reduced contact temperatures.
  • Durable adhesive protective coating with high resistance to water and dust adhesion.
  • Excellent resistance to rain, snow, moisture, and water wash-out.
  • Minimisation of cold contact metal welding.
  • Remains soft and pliable to prevent hardening or build-up in gear tooth roots.
  • Drains freely from gear guards.
  • Excellent corrosion resistance and protection of bronze and brass components.

NAT-3088 meets P&H Material Specifications 520 and 464 and Bucyrus specification SD4713.
