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

Very well made. Shipping was a day earlier than expected.

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

Received an EMPTY Amazon bubble mailer, signed sealed and delivered on time.

good bearings, really good value for price, need some breaking in before they run smooth at moderate rpms (battery operate hand-drill)...

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.

Very low cost but seem OK I used these in a toy I built probably over kill but at less $1 each nothing else can match them.

as described

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.

didnt last 20 days in electric motor not c3 not quality only buy japan bearings China Junk

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