Abstract [en]

Four angular contact ball bearings were tested using two different lubricants. Three tests were made to study the influence of refrigerant concentration, and the fourth test was aimed at comparing the influence of lubricant structure on bearing wear rate. Scanning electron microscopic images of the tested bearings showed that the contact surface between the ball and race was chemically attacked in bearings operating with a refrigerant dilution of 23% R-134a. The lubricant that was formulated with shorter acids gave the highest wear rate
