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

I plan to use them in construction of a metal bender.

They are what they say High quality

These are very cheap made bearing and will not hold up under a lot of pressure if youre looking for a high stressed bearing keep looking but, if not they will work for small projects however they do require additional grease, a simple fix but expect them to be slightly stiff until additional grease is added, over all not bad for the price

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

Great quality

Good bearings for the price, I Designed a cable carrier and used these as rollers. Worked great

I always worry when ordering bearings online that theyll be too far off on the measurements but, see for yourself. The inner and outer rings are as thick as they look, and theyre rock solid. Great buy.

It makes a really big difference when you have a 1/2 rod and these are slightly undersized. I assume these are millimeters. Because I had to shape down my rod maybe a 1/32 or more to get it to wedge on. And I have no lathe, so the rod isnt even. And now the gear I have on the other side is lopsided because of it. On the plus side the bearings arent very expensive and they do work. But really, be accurate. I wouldnt get these again because of that.

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.

Slightly over sized center. Closer to metric than standard. Still worked in my project. Just a bit sloppy
