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

Great quality

Fits like a glove. Works on ti-lite wheelchair front caster forks. And spinergry Spox rear hubs.

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

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

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

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

SEALED GREAT IN A DUSTY CONDITIONS FOR SMALL LIGHT AXLES

Had a hard time finding these for the wheels on my wheel chair. Should have gone to Amazon first! Installing them was easy and they work great.

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

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.
