Hananta, not a lot to go on here. Are the air end bearings the source of the overheat?

You need to get an Atlas Copco repair person to check this out for you.

 Possible causes of high element temperature
by: Amusa Olatunde

1,check condition of the cooler,if it is air cool,steam washed,but if it is water cool,you need to descale the cooler with a chemical called dynamic descaler which we are using in our plant currently and it save alot in buying of cooler altime.
2,Check condition of thermostatic valve if okay,if not replace.
3,Check if oil filter is okay,if not replace (quality of oil filter determine this.)
4,Check condition of the oil stop valve,if possible replace the kits
5,Check for excessive leakage along the line or the consumption is higher than waht your compressor id deliverying.
6,Check sensor condition for malfunctioning
7,For air cool,check if the direction of the cooling fan is right/correct.
8,Ckech for low oil level,if loe top up
