Frequency of re-lubrication depends upon operating conditions. The bearing operating temperature is the best index
for determining a re-lubrication schedule. The following chart gives the frequency of re-lubrication based upon
continuous operation for various operating temperatures and can be used as a satisfactory guide for determining
when bearings should be re-lubricated.
