Mobil Arapen RB 320 (5 Gal. Pail)
Developed for use on roller bearings of railroad car journals where no provision is provided for in-service re-lubrication, Mobil Arapen RB 320 is an NLGI Grade 1.5 long-life, high-performance grease with a mineral base fluid and mixed lithium/calcium soap thickener which withstands exposure to water and a wide range of temperatures (-20 to 120 degrees C). Mobil Arapen RB 320 is specially formulated to resist chemical deterioration, inhibiting production of acids or deposits that reduce bearing life. Its high oxidation stability and effectiveness against shear and friction over prolonged service ensures equipment integrity. Mobil Arapen RB 320 has negligible effect on seal materials and retains its effectiveness over lengthy periods of storage or heavy usage. Major manufacturers of railroad journal bearings use Mobil Arapen RB 320 as the factory-fill lubricant, and it is fully approved against Specification M-942 of the Association of American Railroads for Journal Roller Bearings Grease for non-field lubricated bearing applications.
