Uxcell 681XZZ Groove Bearings Shielded Review

I was hesitant to purchase these industrial and scientific bearings, but I'm so glad I did. After I put them to the test, I was thoroughly impressed with their smooth and efficient operation. The shielded design helped prevent dirt and debris from interfering with their performance. However, the only downside is that they were slightly more expensive than comparable products on the market. Overall, I highly recommend these bearings for any power transmission application that requires precision…

Perfect size for kendama. Replace the bead with one of these to keep the rope from getting tangled and your Tama spinning like crazy!

I used them for kendama (Japanese toy, just amazing). I can't tell them from the orientations I had on my Krom or Sweets kendams. They are the right size and work great to prevent string tangling.
