Right.
If you replace the $7 bearings with the cheap import ones - then what -
do it every year ?

Plugged it in and it runs fine. Fairly quiet!

Question: Tear it down further to look at bearings .. or .. use as is.

I vote, if it works, don't fix it. ;-)

Difference in price from cheap crap import to decent quality bearing
is likely less than 20%. Going for the ultimate, a factor of 5 or
more. If you go to the work of changing them, use good enough parts
that you only need to do it once.


When I wanted an idler bearing for a drill press pulley, the guys in
Medford wanted $20 and change for an SKF bearing and retainer
snapring. Nealy Bearing here in GP sold an import and retainer to me
for $7 and change. That's a wee bit more than a 20% difference.

Some day, if I can get enough crap moved out of the shop to get out
there and work in it again, I'll install it. sigh
