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

Exactly as described. Havent used the machine yetso dont know how it works

Not a precision product but the price is right for the fan I was using them in. They will surly out live the motor.

Cheap bearing that didnt measure to the dimensions as advertised. If you need precision this wont do or maybe it will depending on the manufacturers quality control. I ended up paying 5 times more with McMaster-Carr but getting the precision for my application was worth it.

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.

What definitely used them again

Exact replacement for 2 horsepower motor. The stator and windings of the motor were in good shape and it seemed a shame to have to change out the entire motor. The existing bearings were worn from years of use and the quality of the motor dictated that changing the bearings would bring this motor back up to perfect condition. Good match and back up to its original quality.

You cant beat these exact replacement bearings. Now my barrel fan will keep the animals cool for years to come.
