Carbon-Phenolic Cages for High-Speed Bearings. Part II - Bearing Evaluation with a Multiply-Alkylated Cyclopentane (MAC) Lubricant

Abstract

This is the second part of a three-part series of reports to investigate carbon-phenolic bearing cages in high-speed, lightly lubricated bearings. This portion covers full-scale bearing testing with carbon-phenolic and cotton-phenolic cages impregnated with multi-ply, alkylated, cyclopentane (MAC) lubricant, commercially known as Pennzane(trade name). Experimentally, it was found that bearings fitted with the carbon-phenolic cages generate more heat than bearings fitted with the cotton-phenolic cage. This is the opposite of the intended result. The difference is attributed to damage of the steel raceway with carbon-phenolic cages. This occurred because of wear debris generated from the carbon fibers in the ball pocket. Additionally, the study provides a useful assessment of heat generation in lightly lubricated bearings with composite cages and the effect of thermal preloading on bearing heat generation.
