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.
