Red Silver ABEC-9 608 RS Skateboard Longboard Bearings (8PCS)

You get what you paid for. The ability to roll around.

Good bearings

There is a Grease , like petroleum jelly . So I have to clean all the bearings then when its all clean I have to lube it again with Speed Cream . So for now i have to give it 4 Stars . Then I ask my son hows the bearing and He said its like Bones Red Bearing . Not Bad For the Price ...

Works really well.

Like- Price Abec 9 (supposedly) Still works for my application (clock) Dislike- Tolerances. Have side wobble. No up & down wobble. Just makes me wonder if they actually are the highest ABEC. Not machines perfect. Outer bearing race has imperfections on the edges. Just cut out metal in some places. Luckily not more. Biggest dislike = not all bearings spin the same, even being degreased and with no seal cover. Bearing are definitely not uniform.

I used all eight of these to make a spool holder and roller for my Prusa i3 MK3S 3D printer as the cheap chinese ABEC 7 bearings I bought felt "crunchy" and would stick, well these solved all those issues, I will be reordering these often for all my 608 bearing needs for my projects. Update: I have purchased four sets of these bearings as they are just perfect for my 3D printing applications. They are inexpensive but very nice quality, incredibly smooth. They have consistently been well worth the purchase

Replaced the bearings on my sons scooter. Clean, well sealed and greased. Purchased the 9 to upgrade the bearing quality. Would purchase for most skate type wheels.

No idea if they are sand proof…….

They are bearings. They do bearing things. As with any bearings, longevity comes down to maintenance.. They do not come greased so the first thing I did was use automotive bearing grease and pack them full. So far they have held up a season of riding and no grinding and crunching.

This bearing seems to be ok quality. They run smooth. These bearings have barely any grease in them though. I put just a dab of bearing grease in by popping out the seal with a pin then push the seal back in place. Only use a drop of grease if you do this. If you pack it full of grease, the grease will eventually start coming out of the seal with the bearing heats up. (I speak from experience). If you re-grease these bearings occasionally, you'll double the life of them. I'm using this bearing in a Minn Kota 30lb thrust electric trolling motor to replace a cheap rusted out bearing. The motor runs smooth again.

If using for skateboard or longboard, clean the stock grease off and add sewing oil or speed cream then these work great. The stock grease is no good as some others have said. For price and with better oil they are good

I put these in my moxi quad rollerskates and works great

Works well
