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

I really dont know the quality of this product because the item just arrived today, however, delivery service was very fast within frame time of process, thank you and Happy New Year to all.

Be ready to grease them! Can’t attest to longevity as I just installed them in my spindles last week. I’ll second what other reviewers have said in that you WILL WANT to pop the seals and pack them with grease. One spindle I had previously replaced the bearings on had more grease after 3 seasons than these did out of the box. They are smooth tho, and fit well.

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

Well, while I dont know how long these bearings will last, they look exactly like the ones that were in my pump motor. They installed with the usual way you install bearings, had to be pressed on and needed to have some heat applied to get them on the shaft and in the motor end pieces. But, I am glad I got them, because, with a few hours of work, I saved a $400 pump. Now, I have a back up pump for my pool, ready when the next one fails. Good bearing for a good price.

Bearings fit perfectly used for S2000 idler pulleys

Installed yet pump still some what noisy.Could be quieter.

worked as it should electric motor

this bearing failed within week noe good quility makin loud noise whithin week

For less than $10 it stopped the loud whining of the pool motor. I thought I would have to replace the motor for $500. Runs great now and very quiet.

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.
