I frequently see a maximum allowed oil temperature of 194F (90C) in machine bearing applications. I know the oil life decreases rapidly at higher temperature due to oxidation, but what is the basis of the 194F limit? So many hours of life?
Also, in a ball bearing, is there any known correlation between the oil sump temperature and the peak temperature of the oil in direct contact with the rolling elements, i.e., localized hotspot as the ball shears through the oil film?
Any insight will be appreciated. Thanks...
