NSK 608ZZ 10Pcs Precision Bearings 8x22x7mm, Rotating Quiet High Speed and Durable ＆ Double Metal and Pre-Lubricated, Deep Groove Ball Bearings.

bought about 20 sets of these for building an animatronic pentecostal with my son. they worked out very nice. perfectly smooth and quiet.

I replaced the bearing in my flex shaft with these. The run quiet and cool even at high speed.

Out of the box bearings moved easily. None were stuck.I used this to restore my Skil 6225 corded drill. The motor arbor utilizes a proprietary bushing at the quill end and a proprietary bushing at the handle end. It was making an awful noise at the handle end (near the armature with the carbon brushes. Upon inspection, there was excessive play in this area and I came to the conclusion that the bushing was worn out.I bought these bearings with the idea of using them in various things (my Skil drill being one of them).The bearing was a perfect fit on the drill arbor. A little tight, but I used the original brash bushing as a guide and very light tapping to seat the bearing. A few trial and error taps, and I slowly migrated the bushing to its desired position. The diameter of the bushing was very slightly smaller than the diameter of the bearing. I had seen a You Tube video addressing this, so I did the same thing: I cut a strip of aluminum from a soda can: width about the same as the bearing, and length was the diameter of the bearing. That extra thickness seated the bearing really well.Drill was reassembled and now it works great. O BTW during the same restoration I also replaced one of the carbon brushes (reviewed elsewhere). Sorry didn't take any pictures.I'll be using these bearings in a shopvac repair in the future.

These bearings were purchased to replace worn out ones in a Dayton fan that it is used for recirculating air in our house. The original ones lasted 10 years so took a chance with these as a replacement. They have been in about a month or so and are still running quietly. The original bearings were much tighter in the motor housing and difficult to remove versus these that I could press in by hand. I guess time will tell how long these last but so far so good.

I needed to repair my wireless fan and air purifier because they made noise when they were running. First, I bought and replaced several brand of abec 5 bearing on Amazon, but they make more noise because they are cheap and Chinese brand. Finally, I bought NSK's bearing, and I replaced it. My wireless fan and air purifier doesn't makes any noise. Do not buy Chinese maker. Don't waste your money.

Perfect replacement for band saw blade guides.

These are a bit more expensive than other similar Bearings here, but are far superior. A quiet, smooth running, Bearing.

My ac fan was very noisey. To buy a brand new fan. It will cost $125. Took fan motor apart and found bearing number. Install new bearing and I have a quite acUnit now.
