Works for my application. Size seems pretty accurate. Quality seems good. My application is low speed so not a really good test.

The bearings I got were spot on .5in. Initially I thought they were too small but I belive the rod I'm using from home depot is just over sized.The quality isn't really there for me, LOTS of resistance and doesn't spin well. Probably not going to be what I need but at the end of the day they aren't expensive so I can't really be mad about low quality.

These are dimensional accurate and allow for proper interference press fit based on engineering handbook. They are smooth and pre oiled, place them in my air conditioner fan as the oil light bearing failed. These bearing are used outside and they have not failed yet. Always use in pairs and follow proper engineering practices when sizing and using.

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 isn't even. And now the gear I have on the other side is lopsided because of it.On the plus side the bearings aren't very expensive and they do work. But really, be accurate. I wouldn't get these again because of that.

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
