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

worked well for my application with rollers.

If you dont use a wheelchair, consider yourself deeply fortunate—not because you can walk but because you dont know the misery of dragging yourself through hardware stores trying to find the right size bearing to buy for $16 each when yours decides to liberate itself from your caster in the middle of a pandemic and your chair is a useless hunk of steel without it. But thanks to these bad boys, instead of that experience, or the exponentially worse option of waiting three moons for my service provider to replace it, I can just take my casters apart myself and get rolling again for a fraction of the price.

They are what they say High quality

Good

as described

quickly. Engineering and manufacture. Rugged with amazing value for very low price.

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

I bought the bearings to make a Drum Sander attachment for my drill press. They are of good quality and delivery was fast. They will work out perfectly for the project I am making.

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.

Reasonable quality
