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

They worked perfectly for what I need I rebuilt an idler pully on a mack granite dump truck the pully new was 150 new for less than 10 bucks got it rebuilt and working great its only been on for a little while but holding up fine also measure everything 2 or 3 times I used a micrometer to make sure they were the size I need arrived perfect

Worked good

Work like it was intended to, the right part for the right price. Just make sure your size is the same.

Arrived as expected and alreay installed on the drive assembly of my snowblower!

Fixed the bearing on my tensioner. Very happy, and I have a spare if it goes bad again.

Arrived on time, only 2 days after I ordered it. It was the exact size I needed. Works great so far.

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

Perfect fit

I wasn’t sure about the fit but these worked on an older “1975ish” 1hp Hayward super pump. It was my back up in case my newer pump failed. It is currently filtering my pool and the 2010 pump is sitting on my bench for a rebuild. I will be ordering these again.

Its all good
