Required viscosity at temp for babbitt bearings?

Read our primer articles on Grease Guns and Oil Sight Glasses.

I'm at home, so details escape me.

I'll fill them in in the morning.

But are there general guidelines for required viscosity at the oil wedge?

I'm looking at about 4" dia, 4500 rpm, Type 3 babbitt.

revised details

dia = 2.25"
Bearing length = 5.5"
RPM= 4000

Thanks

There is a formula tho I do not have it handy you need load, speed,size bearing and you will get a vis minimium sorry but I have it all stashed away where I can not find but perhaps some one wil have it or do and internet search it is a basic commonly used formula.

Wild ass guess a ISO VG 100
