Review on 🔩 Uxcell 2mm x 5mm x 2.5mm Shielded Miniature Bearing - Power Transmission Products by Kory Shelton

Poor quality bearings. Bought to fix two ATV bearings. When I replaced them, the motors sounded just as bad as when they first started. I know I didn't damage the bearings when I installed them because I slid them into place with no tools, just my bare fingers. But the real problem came later. I tried to remove the built in bearings and they literally fell apart in the process. The outer clip has become one with the motor stator housing. I probably could have taken it off with more effort but at the time it wasn't worth the effort so I decided to just buy a new set of motors and throw them away. Then why two stars? Because they're pretty cheap and probably work fine for non-critical applications. If your application requires precision and reliability, don't rely on them to get the job done.
