6203-RS Sealed Bearing - 17x40x12 - Lubricated - Chrome Steel (2 PCS)

Worked just fine so far in my industrial carpet and floor fan.

Worked well tight fit.

Theas actually have my pool pump running quite than the factory new ones ever did.

Great product.

Nothing

Seem to be quality bearings. One third the price of an auto parts store.

Worked as needed

Bought these for Pentair pool pump to quiet worn bearings that had been operating for 5 years. Unit ran ok for several days. Maybe 6 hours run time. Then high pitched squeal. One bearing was bad out of two. Imagine that after only a few days. Replaced Both bearings with another brand. It’s been a month since I replaced them and they are silent.

Pulled the seal out, they had no lubrication in the bearing

Good bearings
