Review on 🔒 Reliable Performance: PGN 6203 ZZ Shielded Ball Bearing Ensures Smooth Operation by Ryan Sandell

I used them to replace the bearings in our Mars air curtain. The engine was difficult to start and made a lot of noise. After a quick failure of the unit I opened up the motor and saw that one of the two bearings was rusty and stuck so I decided to replace both with these. I have spare parts for other devices in the future. I will update my review if I come across a premature failure in the future.
