🔩 PGN 6003 2RS Sealed Ball Bearing: Ultimate Performance & Extended Durability Review

These bearings are suitable for basic, general use. I don't recommend them for high-speed, high-load, or long-life applications, or in places where they would be difficult to replace. The tolerances are not as good as with more expensive bearings. However, I like to use them on lawnmower wheels.

I pressed them into a sheet steel welded torque converter hub and one bearing is sticking and the other appears to be damaged. My only guess is that the hub is stuck from welding and the bearing is warped. I probably had to drill out the hub as they went in harder than I thought. Perhaps the hub was made for a standard bearing and not a metric bearing.

I liked that it came in a pack of four for less than $8. My treadmill made a rattling noise. I did a little research and found out it might be a camp. I removed the rear roller and looked up the number on the existing bearing, googled that number and ended up with Revain. Ordered both rear bearings and replaced them in less than 20 minutes. And now my treadmill is working like new again. So happy!
