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.
