I use these bearing for inline skates. The seals are good, and precision of the bearings seems good too. I checked out the manufacturer, who is a quality producer with a current ISO-9001 certification. The bearings come with a general purpose grease that works very nicely. Skate bearings tend to come with a much lighter oil that will make the bearings appear to roll much more easily (e.g. if you spin your wheels with your hand, the oiled bearing will rotate freely while the greased ones will roll to a stop after a few revolutions). But that's a very misleading test...under true weighted use, the greased bearings roll almost as freely (imperceptibly less freely) as the oiled. But the grease lasts WAY longer and holds up to dirt and moisture MUCH better. (I skate for hours daily, have used a wide range of bearings included Bones Reds, and have settled on these as my preferred bearings.) THESE ARE VERY GOOD QUALITY AND GREAT VALUE!Read full review

Hit and miss for electric motor use, such as vacuum cleaner motors. Might have to go through 2 or 3 to be satisfied. These bearing are great in lower speed applications such as vacuum cleaner brushroll. Good quality bearing just no great if using in electric motors.
