Evaluation of Synthetic Hydrocarbon Instrument Bearing Oils.

Abstract

The work reported herein resulted from the testing of three viscosity grade synthetic hydrocarbon oils to determine their suitability as replacements for Specification MIL-L-83176 superrefined mineral oils. The results of the tests were used to compare properties of these oils. In addition to those of an ester type instrument bearing oil qualified to Specification MIL-L-18486. The results show the synthetic hydrocarbon oils, of comparable viscosity, to possess superior chemical and physical properties to those of the MIL-L-83176 type mineral oils and similar properties to the MIL-L-18486 ester oils. Comparisons of R-4 Bearing Performance Tests show operating lives of 4-10 times greater for the synthetic hydrocarbon oils than for the mineral and ester oils. Based on these results proposed specification requirements were developed to cover the use of synthetic hydrocarbon oils for instrument bearing application.
