SEALED GREAT IN A DUSTY CONDITIONS FOR SMALL LIGHT AXLES

Nice bearings, replaced my old worn out wheel bearings in my Honda HR215 lawn mower. Had to ad a washer to take up a bit of play on the axle, does the job fine. I went to a bearing store and they wanted $9.50 a piece for these. Got 10 for $10 with this kit

These seem to be good quality bearings.

Sorry guys, I bought 30 of these for a heavy slide out drawer. Theyre nowhere close to 0.500 internal diameter. I opened one ten pack to find ID OF 0.0472 and an OD of 1.102! Coincidentally exactly 12mm x 28mm. No way in Christmas are they going on a 1/2 shaft. Infuriating.

They are what they say High quality

Great quality

Bearings were exactly on with measurements and quality, I used them to make 5 small wheel drums on my 2 x72 belt grinder. Tight and true project came out better than expected....................

Slightly over sized center. Closer to metric than standard. Still worked in my project. Just a bit sloppy

It makes a really big difference when you have a 1/2 rod and these are slightly undersized. I assume these are millimeters. Because I had to shape down my rod maybe a 1/32 or more to get it to wedge on. And I have no lathe, so the rod isnt even. And now the gear I have on the other side is lopsided because of it. On the plus side the bearings arent very expensive and they do work. But really, be accurate. I wouldnt get these again because of that.
