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

Nice bearings, replaced my old worn out wheel bearings in my Honda HR215 lawn mower. Had to ad a washer to take up a bit of play on the axle, does the job fine. I went to a bearing store and they wanted $9.50 a piece for these. Got 10 for $10 with this kit

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.
