1 - Sealed-for-life
2 - Re-greasable
3 - White metal
I would not expect to see an oil-lubricated white metal bearing at this power level.

Well, it is a vertical motor. We have a centrifugal pump run by this type of motor. Presently it is a oil cooled motor. We want to change to grease cooled motor. One of motor supplier when approached said he can provide such motor with grease cooling in place of oil cooling. The oil cools SKF 7219 double face to face thrust bearing at fan end and SKF 6320 bearing at coupling end.
Ok , what will be the maximum unattended duration with grease cooling.
Thanks

RE: Continous duty Grease Cooled Motor
If you buy a new motor with greased bearings, that is ok since the OEM would have designed the motor accordingly.
RE: Continous duty Grease Cooled Motor
My question still , is a grease cooled motor of this specification available/ produced in industry.
RE: Continous duty Grease Cooled Motor
Motors are almost always air cooled, either directly or using an internal air circuit to some form of heat exchanger.
