Check your directory for "Applied Industrial Technologies".
Or call....760-241-7238 for the "Hub" store out here
in Victoville, Ca. They have 400 stores world wide, and
have every bearing know to Man. They carry bearings
that even the "bearing houses" don't carry.
And they're may be a store near you. Plus that, they
have every grade of bearing....up to like 36,000 RPM.
And the bearings they carry have the real seal up
front....not like those cheap ones with the phony
metal shield....which isn't really a seal, but a dust
shield.....

They cost a little more, but are worth it !
