lubrication oil ring issue in Sleeve bearing Pump

Hi all, 

we had issue with sleeve bearing failure,  the issue began with high temperature until the babbitt failed,  we suspect the oil ring is very heavy. Please,  Can you share experience in this kind of problem.. 

*how can we know if the oil ring was bad selected?

*diameter of shaft is 2,6 inch, rpm= 3600
