Donepart 6203RS Ball Bearings 17mm ID 40mm OD 12mm Width C3 High Speed 6203-2RS Sealed Bearings for Electric Motor, Pool Pump, Wheels, Bike, Mower (4 Pack)

Berings work fine on my pool pump motor

Unbelievable good price and they seem to be quality made. They were my minibike chain sprocket and fit perfectly.

Just the bearings that I needed for my job. It takes kind of long to get them though.

Used these to replace two completely destroyed rear crank bearings on a Sunny Spin Bike, model SF-B1877. These are the same "model number" as the warranty parts. They were easy to put in place and work great. Not sure of the longevity of them since I only just replaced them. Being that they came in a four pack though, I'm happy. Of note, if you're replacing bearings in a spin bike, you'll need two of the four - not just one - so keep that in mind.

Bought to replace the propeller shaft bearing in me 1996 Murray Snowblower. So far they are holding up okay. Perfect fit. Time will tell.

This was advertised as C3 bearings and I received standard bearings. I was expecting the bearings that had C3 stamped on it.

Exact size for a motor being overhauled. Great price and fast shipping.

I use this all the time on winch motor.

Installer sur une pompe de piscine.

Common size bearing, can use for multiple applications. This one was the electric motor for a wood splitter. Great price!

Correct size and easy install

Bonne qualité

Good product and good price
