uxcell 6810-2RS Deep Groove Ball Bearings 50mm Inner Dia 65mm OD 7mm Bore Double Sealed Chrome Steel Z2 2pcs

Used to replace Shimano hub bearings No longer have play in the rear wheel. Very smooth rolling. No issues after the first few rides.

Great bearings at a great price!

Fit great and are really smooth

Used these bearings to fix a bottom bracket on a bicycle with a 30mm crankset… these worked perfectly, saving me about $60. I could not be more pleased.

Perfect replacement for Wyze Pan Cam 3 Moisture seeped into bearing and corroded it

Very well made and dimensionaly correct

I was testing a bicycle drive design. I bought these because they were the only sealed bearings that would fit my experiment. I hoped they would last long enough to get my data, but I expected them to fail. They didn't. I'd give these a five but I rarely give five stars unless something goes above and beyond. I've not had them in use for long, but I have stressed them extensively and they are holding. If you have a light duty use then these will likely serve you very well.

Works as intended. Size very close. Sealed nice.
