What may cause compressor bearings temperature to get abnormally high

Firstly check that your compressor high temperature wasn't cause by other reasons like a lack of cooling.
High bearing temperatures usually sign of:
1. Seizure of bearing
Check the bearing or replace it with spare. Check crankpin surface condition, remachine if necessary
2. Clearance in bearings is to small (wrong installation, misalignment, wrong bearing etc)
Set the proper clearance.
3. Lack of lubricating oil
Increase the lubricating oil pressure. Replenish the oil.
4. Increased temperature of lubricating oil
Replenish the oil if level is too low.
5. Deterioration of lubricating oil
Change the oil
