Some additonal informations - Is this a new installation? Yes, both the pump and motors are new - Have you verified your instrumentation? The sensors were calibrated just before the measurement - pump speed =? 740rpm - # of balls in the suspect bearing = ? Roller bearing, 14 rollers...

I am working on a new 45kW centrifugal water pump, which is >70C at the roller bearing pedestal. I wonder what' s causing such high temperature. The vibration measured at the bearing pedestal is indeed very small. The pump seems to be well balanced and lubricated.
