R1810ZZ sweet!

I used these bearings in a shake testing instrument. They run quietly and are rugged enough to take a good deal of shock without damage. The small size makes them easy to integrate into compact assemblies.

I expect to keep using these.

These little bearings do a great job for me. I use them as con-rod bearings on a small (1 3 hp) steam engine stacking them three wide and they hold up better than I expected. I'm getting around 40 50 hrs out of them depending on load rpm's.

I ordered from VXB before I will again.

I used my order to replace bearings in a small fan.
