PGN - 6802 Ceramic Sealed Ball Bearing - 15x24x5-61802 Si3N4 Bearing

Had to install new bearings in a PowerTap hub on a road bike. This was a perfect replacement and the price was very affordable.

Good bearings! Used to rebuild the through axle hub on my mountain bike. My bike takes a lot of beating due to the nature of biking that I do (mostly technical trails). Hopefully these will last. So far, perfect fit.

Bought a set of these on August 23rd 2019. Rebuilt a free hub on my road bike and they have already seized up and rusted. Sealed, I would not say that, there was water in the bearings. Thought they were better than that.

One star off of 5 is that if you put just the slightest of tension on the sides of the bearings when bolting down it vastly affects the smoothness. Maybe that was just me in my use but its noticeable to make me want to go back to steel bearings. Also if you are using a hammer or bearing puller to knock these in or out it worries me with ceramic having that force on ceramic bearings vs steel. I know the steel won't shatter or crack and ceramic can so you have to be cautiously careful which kinda is a pain in the bum.Good value for ceramic however and love thats its a two pack. I used them for the bike rims.

A bit on the slow side but smooth and last longer than ACER bearings. Not better than VXB bearings.

Bought a pair and both are rusted out of the box. There is no grease protecting the steel races, the outer race is badly rusted and not usable.
