Now that could be interesting for a submersable aplication, however I
would think that the teflon race would be a bit soft.

And I can't see anything 'cheap' about them compared to steel ball and
roller berings. Otherwise the automotive industry would be all over
them.


I'm wondering how they would dissipate heat. I'm thinking, for example, of
boat trailer bearings. Does the oil or grease in a heavy duty axle bearing
help spread the heat around?

I remember the old Mastercraft trailers it was my luck to assemble at my
father's boat store. What a pain in the ass that was. But the axle
bearings were sealed. No rubber dams, no oil caps. At the end of the
season, you pulled the bearings, dumped them in a vat of gasoline to clean
them off, repacked them if they were okay, and sealed them back up into
the axle.



Only idiots used gasoline! Had to be a crappy operation to not have a
solvent tank. While in high school, working in Richfield station, my boss
stated to never use gas to clean. He took a couple months to replace the
hair loss from using gas is why he was adamant about using solvent..
