This has lasted 6 years so far. I think I will replace it for good measure.
Idler pulley bearing for my 03 Accord. I installed it in 2019 and it still feels pretty good. For $6 I will take 6 years of daily driving.

these Indian made bearings are good. I'm only using them in a 1/3 horse electric motor, so that's not asking a lot of bearings, but they arrived quickly, were sealed properly, and went in just fine after a night in the freezer fine.

Genuine SKF 6203-2rsh/c3
These appear to be genuine SKF Italian made 6203-2rsh/c3 bearings. Should be a good replacement bearing for my 7.3 top idler.

Easy Install
I had to replace a bearing in an older Craftsman lawn edger. I checked the bearing size, ordered a new one from Amazon, and got it in two days. This bearing dropped right in place with only a little prodding. I reassembled the shaft and it's now working like a charm.

They mislabeled the size!
The dimensions I ordered were different than advertised!

With these bearings and a press it was about fifty and now they sound great.
I ordered these because I have a couple Fords and the serpentine belt on two of them were making noise. I pulled the idler and tensioner off when I realized they were the problem. For both parts on both cars it would have been over two hundred. With these bearings and a press it was about fifty and now they sound great.

Received the bearings today they are made in Italy very nice quality and I'm eager to install them in an old unisaw that i am rebuilding. The bearings also came much faster than was quoted. The bearings were in a sealed box and were also sealed in plastic inside the box.
