NRL-MB-20B: AN IMPROVED INSTRUMENT BALL BEARING LUBRICANT

Abstract

Operational requirements for thin film-lubricated miniature ball bearings for synchro/servo mechanisms are too severe for some marginal Specification MIL-L-6085A oils. The more critical requirements for these lubricants include low volatility, corrosion resistance, thin film and bulk liquid high-temperature oxidation stability, acceptable low temperature properties and cleanliness. A prototype formulation, was developed which incorporated the physical and chemical parameters required of the lubricant. The formulation is based on a neopentyl polyol ester and a dibasic acid ester mixture and contains additives to impart oxidation and corrosion stability. Laboratory data are presented to provide the basis for a comprehensive specification which will assure the quality and performance required of the lubricant.
