Replacing sealed Cat fan hub bearing

Has anyone who had to replace a failed sealed fan hub bearing on their diesel engine tried to replace it with the greaseable bearing? Is this even possible? I was going to call either Freightliner or Cat but not sure whose bearing/holder this is and when it is installed.
Maybe this would be costly to do it instead of just replacing with the original sealed bearing. One shop told me they weren't sure if the greaseable one was even available any more. After telling me that I didn't figure it would do any good to ask anymore questions.

Could be worth a call to the free Freightliner help line , have your serial number handy.
Sorry the phone number is in the coach and it's raining C & D out there. 1-800-FTL-HELP I'm sure that's the letters .
They can say for sure, but I think it's a Cat item.

I haven't had to do anything to mine, but it is a CAT bearing and I know that your can get either the sealed bearing or the one with the grease zerk on it--either one will fit.

Thanks, I kind of figured it must be a Cat bearing as the way the engine would be delivered to Freightliner for installation in their chassis. I changed the serpentine belt several years ago but the bearing wasn't on my mind at that time so I don't remember what it even looks like. To just replace the sealed bearing would it be pressed out of a holder and the new bearing pressed in? And if changed to the greaseable zerk do you suppose the same bearing holder works or if that has to change also, which will up the cost.
