Sackorange 10 Pack R8-2RS Double Rubber Sealed Roller Ball Bearing 1/2 Inch Bore 1/2 x 1-1/8 x 5/16 Inch ABEC3 Precision Bearing for Electric Motor, Wheels, Home Appliances, Garden Machinery

Very low cost but seem OK I used these in a toy I built probably over kill but at less $1 each nothing else can match them.

Sorry guys, I bought 30 of these for a heavy slide out drawer. Theyre nowhere close to 0.500 internal diameter. I opened one ten pack to find ID OF 0.0472 and an OD of 1.102! Coincidentally exactly 12mm x 28mm. No way in Christmas are they going on a 1/2 shaft. Infuriating.

They’re bearings and they fit. What more do I say?

Bearings were exactly on with measurements and quality, I used them to make 5 small wheel drums on my 2 x72 belt grinder. Tight and true project came out better than expected....................

They are what they say High quality

Very flimsy. Plus they glad as them as available in 2 days, then report they cant ship for 4 more days while theyre adopted in from China. Since they are flagged in the store as ready to ship you cant cancel them. Avoid at all costs. But from a respectable supplier. The ones I bought failed under slight load.

Great product working perfectly for replacing the bearings in my jeep running stroller

Bought these for use on a rotomolding apparatus I am making! They work great.

Received an EMPTY Amazon bubble mailer, signed sealed and delivered on time.

Got for a SSR 50cc dirt bike and they were slightly too big for the bolt and the wheel they were supposed to go into. I had to get pretty creative but I got them in and Im glad there was 10 of them because I damaged three or four of them trying to install where they didnt belong . Whats installed and rigged up worked great very happy with product and price
