Perhaps one of the absolute cheapest ball bearings assemblies is

a dozen at a time for misc projects, and just have them on hand. I
probably have 30 or 40 of them in my spare bearings right, not and
a small package of them in the center drawer of my desk. You can
get them in better grades if you want to, but the plane old cheap
import version holds up just fine for hundreds of projects, not the
least of which is skate wheels. They are even cheaper than buying
bronze bushings from most of the common industrial suppliers. I
know. I have a few 8mm bore bronze bushings on hand too.

I've wondered about this for years. I think I might even have asked
this group before. Is there a big brother to this bearing?
Something bigger and nearly as common so that it can be priced to
keep a bunch of them on hand for miscellaneous project?


Hi, Bob.
Can't answer the question.
But, several years ago I bought a used/abused Chinese metal band saw
at a local business "garage sale". $35.00. Keep it at the plant.
Similar one at home.

The abused one needed bearings. Checking for them on-line, I
discovered the number matched the bearings for skate boards and
bought a bunch on Ebay. Worked ok and saw is still going strong.

My identical saw at home uses a different bearing number and I never
check what the difference is.

I use those 608s for the blade guides on my sawmill. They clog, but
both the Z and RS are easy to open with a safety pin point to clean
and regrease (or oil).
