Chevron Black Pearl Greases EP are multipurpose, xtreme pressure, water-resistant greases. They are formulated with ISO SYN® base stock, a polyurea thickener, and rust and oxidation inhibitors. They are black in color and smooth and buttery in texture.

FUNCTIONS
Chevron Black Pearl Greases EP provide outstanding film strength and adhesive properties. As a result, these products are particularly effective in providing superior wear protection in heavily loaded and shock load conditions.
Chevron Black Pearl Greases EP stay in place, sticking to bearing surfaces and, thus, provide excellent lubrication under a wide range of operating conditions. They perform particularly well in roller bearings. These products provide exceptional water wash out results. They perform well in applications where cascading water or actual bearing submergence can occur. The rust inhibitors effectively protect bearing surfaces against corrosion. Pumpability is excellent over a wide range of temperatures as indicated by the Lincoln ventmeter test and the relatively low pressure drop in piping. Oxidation inhibitors ensure long life in storage and in use. In addition, Chevron Black Pearl Greases EP also perform well at high temperatures.

FEATURES
  • Excellent pumpability - Viscosity measurements at grease pump shear rates show these greases will pump easily.
  • High load capacity - As a result of high film strength and overall EP performance, shock load protection and low wear are ensured. Especially suited for roller bearings.
  • Corrosion protection - Pass the modified ASTM D 1743 Bearing Rust Test.
  • Water resistance - Product provides exceptional water wash out results. Performs well in applications where cascading water or actual bearing submergence can occur.
  • Excellent adhesion-These greases stay in place and continue lubricating under most operating conditions.
  • Long lubricant life in storage and in use. Minimized inventories - One grease satisfies almost 100% of the grease requirements of most industrial plants as well as of automotive equipment.
Applications:
Chevron Black Pearl Greases EP are recommended for general lubrication service in both automotive and industrial applications.

These multipurpose greases can satisfy grease requirements of most industrial plants and automotive equipment. They will replace most specialized products. Their excellent pumpability and low oil separation make them ideal for use in centralized lubrication systems. Typical industrial applications are:
  • Presses
  • Antifriction bearings
  • Low and high speed journal bearings
  • Roller and needle bearings
  • Shaker or classifier screen bearings
  • General machinery lubrication
  • Conveyors and run out rolls
  • Electric motor bearings (especially cylindrical roller bearings)
  • Exhaust fan bearings
  • Crusher bearings
  • Pump bearings
  • Typical automotive applications are:
  • All chassis points including ball joints and universal joints
  • Wheel bearings
  • Water pumps
  • Fifth wheels
  • Steering system bearings
  • King pins
  • Other uses include:
    • Construction equipment
    • Agricultural equipment


    Chevron Black Pearl Greases EP NLGI 1 and 2 are approved for the NLGI Certification Mark GC-LB for use as automotive chassis and wheel bearing greases based on ASTM D 4950. They work well in both plain and antifriction-type bearings, particularly those subjected to shock loading. Chevron Black Pearl Greases EP are certified by NSF and are acceptable as a lubricant where there is no possibility of food contact (H2) in and around food processing areas. The NSF Nonfood Compounds Registration Program is a continuation of the USDA product approval and listing program, which is based on meeting regulatory requirements of appropriate use, ingredient review and labeling verification.
