PGN (2 Pack) 6203-2RS Bearing - Lubricated Chrome Steel Sealed Ball Bearing - 17x40x12mm Bearings with Rubber Seal & High RPM Support

Perfect fit for Coleman RT200 mini bike jackshaft. Rolled smooth and good price. Will buy again if needed.

Real deal. Cheap replacement cost.

Used these bearings to rebuild a pool pump, I suspect they will work as well as the original. Downside, not made in USA.

Great value. Fast shipping.

Good sealed Ball bearings

Needed to replace the bearings on my treadmill belt axles. These did the trick, and it is totally quiet now.

Bearing for great for the jackshaft on my Coleman ct200u-ex mini bike.

These bearings were packaged very well they will do the job that I bought them for

I purchased these in June 22nd, 2019 for my pool filter pump. As is sit and write this review, I can hear the bearings screech and scream. I will be looking for another brand this time.

I used one of these bearings to replace the original on a treadmill motor. There wasnt much in the way of grease inside the bearing as delivered. Just a limited amount of some clear substance - more like jelly, really. I removed whatever that was and repacked it with high-temperature grease before installing on the treadmill motor. It has been working flawlessly for a few days now. The motor is now very quiet.
