Could you please assist us about maximum authorized main bearings temperature of our 16SW280 engines for better protection and operation. During this hot season our ambient temperature is really high and we did not find in manuals any information about main bearing temperature limit.
The maximum main bearing temperature is as follows:
Alarm at Tnom. +5C° with a max of 102C°.
Stop at Tnom. +15C° with a max of 110C°.
Tnom. is the highest temperature found on the main bearings during operation on full load under normal circumstances.
Such high temperatures will not be reached without bearing damage, because the max lubricating oil temperature is reached before that.
