Bike Ball Crank Bearing Retainer 1/4" x 9 Balls 4 Pcs Bottom Bracket Bearings for Kids Schwin Bicycle, Crank Bearings Repair Accessories for Genesis Bike

Perfect size and look exactly like the oem ones

Seams like a good quality bearing, mountain bike working like new speedy shipping, and a reasonable price !!!

The bearings are shipped in a plastic case, but without any tape to hold it together, only one complete bearing stayed with the other two floating around the mailer and one completely missing altogether. Seeing as I only need two to fix my bottom bracket, returning and waiting to fix my bike isn't worth it. I still need to install, but the bearings themselves seem of good quality with no poor machining marks, edges, or burrs and a smooth rolling action.

Used to replace bearings on my bike

My wife's bicycle. She's rides this bike almost every day. Thankfully I was able to find the correct size bearings for this bicycle on Amazon.

Only received 1 bearing, description says 4 pcs! Bad service, don't recommend.

I counted the balls and looked at the picture and found that there are 2 different size diameter bearings used on cheap kids bikes. Both have 5/16” balls but the overall diameter is different. So make sure you order the right size. Some of the product listings don’t give you the measurements so it was a gamble. I ordered these and they are too small. Hopefully that helps someone!

After not able to get a replacement at my local bike shop, I searched and found these. I ordered mid-after on a Saturday (14 minutes before the ordering deadline for next day delivery) and received about 15 hours later on a Sunday USPS delivery. They look like they are well-made, came in a zipper-sealed plastic sleeve, and coated with something (Cosmoline?) to protect from rust. As expected, they fit perfectly and I was able to ride the next day. I replaced both crank bearings, even though only one appeared to be bad. It is nice to have an extra set on hand. More than pleased with the price.

Fit perfect in my Grandson’s 20 inch bike with a 3 piece bottom bracket.

Grandson very Happy. Was able to get his bike back on the road.

Needed to replace one of my bottom bracket bearings, this did the trick but I wouldn't say they are quality parts. It will due for now until I can upgrade to a sealed bearing set up. Definitely will need to purchase some grease for installation as the 4 I got were dry as a bone. But for price I can't complain.

Not sure about other reviews… but these bearings were reviewed in great condition and installed on the bottom bracket shaft perfectly…

I don't know what the type is called for my bottom bracket cause I can only find everything but the one I have but it's the one that most department store bikes have & these bearings worked perfectly & including 4 pieces was a saving grace when I installed them backwards the first time and broke them.
