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

good fit

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.

did fit as advertized

Little to no grease in the bearing. Other than that bearings are fine.

Both froze up within 4 hours of use in mower gear box. Worthless

good

Item was of admirable quality! Packaging was stunning. Delivery was magnificent.

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

Very easy to install with the added bonus of no needed maintenance in the future

I was trying to save my Pentair pump motor and found a bad bearing.... replaced it with these but it was too late as the motor coil was fried... was a bad time in my life and waited too long to look into it after I started hearing a strange noise from the motor...
