The specified grease stability times and/or relubrication intervals are valid for maximum
ambient temperatures of 40 °C. Reduce the lubrication interval for a 10 °C increase in
temperature by a factor of 0.7 of the value listed in the table (max. 20 °C = factor 0.5). With an
ambient temperature <= 25° C, twice the grease stability time can be expected; but a maximum
of 40000 hours. Times for operation on 60 Hz systems on request. With pure coupling operation
with flexible coupling, the calculated bearing life is L10h greater than 50000 hours. Comply
with the grease service life and relubrication intervals.
