10 PCS DEEP GROVE 6902 2RS BALL BEARING RUBBER SEALED WEATHERPROOF 15x28x7MM SET

Nice bearings. Perfect fit, smooth rolling with very little resistance. Not enough miles on my road bike yet to comment on durability but I’m optimistic.

I used these as soon as they were delivered. They went to the wheels on my wheel chair. Everything is perfect now.

Replaced bearings in my stans neo, so far so good.

right fit and inexpensive

Arrived loose in a bag, which is fine, although bearings from uxcell came in a plastic case which was nice. These bearings shields are NOT red, they come with a black shield. In fact, I'm pretty sure they're the same bearings that uxcell sells of the same size. These just seem to have a tiny bit more resistance in them, like perhaps there is more grease inside. In any case, there isn't any noticeable friction so they spin well, just not freely (which depending on the application is what you want). They are toleranced well, within .02mm of the given dimensions.

So, the rubber seal isn't red (it's black), but for a bicycle wheel installation, who cares. You dont see the bearings once they are installed.I installed these bearings in a Stans S1 Flow rear mountain bike wheel. I removed the old bearings, using a homemade bearing remover. I took a piece of 1/2 inch steel tube and cut four slits in it approximately 2 inches long. Then bent the ends out slightly, pulled it halfway through the hub and tapped the old bearings out. These replacement bearings went in fairly easy with my homemade bearing press (1/2 inch threaded rod with 2 washers and bolts on each side (picture included). It also pays to place the removed bearings on the inside as they will fit snugly against the new bearings, giving you a straighter install.Once in, the bearings rollled nicely. I will update on their longevity as I ride.
