Looking for advice as to the proper substance to clean these with (rag with PB blaster?) and should I grease them up after and with what grease? Untitled by Jimi Sitko, on Flickr Untitled by Jimi Sitko, on Flickr

Looks like a lot of metal in that old grease. Those bearings may be beyond saving. You can try, but I'd suggest replacing them with sealed pillow bearings.

Asked on FB and got clean excess grease, regrease with marine grade grease and voila. done. wish me luck Great advice if you first make sure that they are even usable. Check for play and runout. Feel how smoothly the bearings roll in their race by hand. Any roughness and you should toss em. When you regrease, clean off old grease from the outside. Inject new grease until new grease ejects old grease then wipe off old grease again. It is perfectly normal for normal pillow blocks to pass grease past the seals when being filled. If you replace them with sealed pillow blocks, be ready to replace again someday. My course of action if they are not reusable would be to replace them with new pillow blocks that can be greased at regular intervals and then following through on the greasing at regular intervals. Properly greased and installed bearings should last for decades. Unless, lets say, they're made in China. Sealed pillow blocks are great at resisting water and should be used where water is invasive. The only problem with them is that all grease will eventually loose some of its qualities and with noway to replace it with clean new grease, it just gets worse and worse until the bearing fails (usually way before a properly maintained lubricatible bearing would.)

It's easier just to replace them. Not much cost and saves lots of time and hassle the big thing....you know for sure the are good.

What do you mean it looks like a lot of metal in that old grease? I cleaned what I could with just a rag and they don't look bad and they both turn fine by hand. Not sure why everyone just thinks they're junk at this point

I've cleaned up, rolled for smoothness, relubed, and gotten good service out of lots of pillow blocks that came on things I bought. Given your description, I don't think they're junk.

They don't make Sealmaster bearings anymore and they last waaaay longer than the new imported ones.

He has already stated that the bearings are in working condition. I believe it would be way easier to wipe them off, inject new grease and be done. With your solution, an extra expenditure is involved in the purchase of new bearings. Plus, you still need to grease the new bearings too. Grease and rags cost way less.

NO don't soak them just wipe them down they are sealed bearings and the solvent will allow the dirt and grit in. use lithium #2 grease and do not over grease them if you see grease coming out of the seals you are over greasing them.
