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

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.

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

None of them would fit on a half inch axel. The inner diameter was undersized on every bearing by 6-4 thou which made them unusable for my project.

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

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

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

front wheel bearings on a toro 30inch timemaster mower

worked well for my application with rollers.

These bearings have a slightly heavier outer race and a cleaner look than the other comparable on here I would assume that should translate to a better bearing. They do turn slightly harder when new.

These seem to be good quality bearings.
