Journal Bearings and Their Lubrication

The high- and low-pressure zones, which are created within the oil on each side of the area of minimum film thickness, can cause oil cavitation in these bearings. Cavitation is a result of expansion of dissolved air or a vapor (water or fuel) in the low-pressure zone of the bearing. The resulting bubble implodes, causing damage, as it passes ...

Why High Oil Temperatures Aren’t Always Bad

You are correct in stating that high operating temperatures encourage additive and base oil failure. The widely used rule of thumb is that for every 18 degrees F increase in temperature, the life of the oil is cut in half. Still, it is common for high temperatures to be recommended in paper mill applications.
