KVENIPremium Skateboard Bearings, Pro-Longboard Bearings, High-Speed 608rs-Ball Skate Bearing ABEC – for Skateboard, Quad Skate, Inline Rollerblades, Scooters Wheels and Spinners (Pack of 8) (Green)

I bought some knock off Chinese crap for a CNC machine. They ended up being terrible. I was looking for alternatives and ran across these. Compared side by side with the Chinese ones, there is no comparison. These ones are so much smoother and are actually the correct dimensions. Not sure how long they are going to last but so far so good.

left longboard out in rain and ruined the bearings. These were great to get my board back on road. Run smooth.

These bearings were exactly what I needed for my project

So I'm waiting on the new wheel I purchased, but they seem to roll smoothly. I hope they're as fast as they seem.

The media could not be loaded. Use dry graphite powder for lube and wear gloves.. at first the won’t spin well, use them for about an hour after first applying the powder and your never going to look back.!
