XiKe 10 Pcs 608ZZ Skateboard Bearings,Double Metal Seal Bearings 8x22x7mm, Deep Groove Ball Bearings.

I too also used bearings for my crazy loud window ac unit. Now it is as quiet as can be. Stamping says 608z but it is double sealed and no bearing showing on other side. So far there great for using for a motor

Great for 3d printer projects

Bought these bearings for use in a Thelin Parlour pellet stove motor made by Exmek. Correct bearing size, and cured the whining/ screeching noise. Been in the stove for a couple of days now, running 24/7, and working fine so far. They don't feel (spinning in your hands) like the finest quality bearing possible, but the stove motor tends to contaminate and destroy a set of bearings about once a year - so if these last a season of stove use, at about a dollar per bearing, that's great.

Purchased for my Sears Craftsman bandsaw as a replacement.

608ZZ is used in may consumer grade motors, such as those for shop fans and blowers. Most of the 608 bearings available on Amazon are "skateboard rated," meaning they are manufactured to loose tolerances and use rubber seals. This means that if you use skateboard 608 in an electric motor, you will get lots of noise and reduced bearing life. These bearings are proper 608ZZ, made to tight tolerances and sealed with metal. The tolerances are so tight you will need to clean off rust from motor rotor shafts for the bearings to fit, this is a good thing, shows that the machining on these bearings are of close tolerances. A close tolerance bearing is a quiet bearing. I use 608 to repair fan motors, and these are even quieter than the new originals sometimes! If you need 608ZZ for electric motors, you will be hard pressed to find a better bearing for the cost than Xike. They are even packaged in a cardboard box and a foam tray, really shows this manufacturer cares about their product. Will recommend and purchase again.

I ordered these bearings to replace one on my treadmill motor. They came professionally packed in form fitted plastic front (a spot for each individual bearing) with cardboard backer. Others had complained about having to wipe off packing wax or grease, but I didn’t experience that at all. They are pre-greased, but the grease is on the inside of the bearing and both sides are sealed. They don’t seem like the fastest bearings in the world (meaning if I hold the center and spin the outside, they don’t spin for a very long time), but in my case the motor would be doing the spinning. They definitely fixed the screeching motor sound and now I have spares to replace this one when it eventually goes bad. It was a heck of a lot cheaper than buying a new motor or treadmill.

Had a bearing noise in the fan on my window AC unit so I tore it down to inspect. I worked for an electric motor repair shop so I had a little upper hand on the repair. Ordered these, put it back together and all is well.To the people complaining about the labeling on the bearings here is a little lesson. A 608 is the exact same size and quality as a 608z or a 608ZZ or a 608RS. Some bearings only put one Z on it because the only difference between a 608z and a 608zz is the 608z only has a shield on one side, whereas a 608zz has a shield on both sides. A 608 is unshielded and a 608RS is a sealed bearing.

These were purchased to be used on a saw mill outback. Saw mill is running so I’m guessing they fit their purpose.
