Premium 20Pcs 608rs Bearings Skateboard Bearings Chrome Steel Bearing Longboard Bearings (8x22x7mm) Double Rubber Sealed Deep Groove Bearing

Not sure if these are still on sale for the promotional or not, but still they are good bearings and I am pleased with them.All measured very close OD and concentric.Checked all IDs with a go no-go 8mm bar and all passed within a few tenths +-0.0002"Most fit just right with 3 requiring a light press approx. 8lbs which is what I consider perfect. .001" off size I would consider sloppy.Being aimed at skateboards I'm sure ease of replacement is a better thing but these are good enough for 2500rpm electric motors. They would need to be repacked with proper high speed grease for higher rpm in my opinion though I did not test for a grease friction heat limit with the factory lube.

I'm happy with these Deep Dream 608rs (8x22x7mm) Skateboard Bearings. 20 bearings for 8 bucks is a good deal for my purpose. I'm going to use them to make pendulums, so I'm not that concerned about how closely the actual bearings match the stated specifications.I will say that, right out of the carton, the bearings didn't spin much when I tested them. These bearings slowed and stopped almost immediately, after I spun them with my finger. I used a pin to pop the side panels off, and took a look inside. The bearings had some clearish gel in them. Maybe it's petroleum jelly - but that's just a guess.To try to get the bearings to spin better, I added a couple of drops of pneumatic tool oil to them. (I used the pneumatic tool oil because it's a medium thickness oil, and I have a big bottle of it.)The bearings spun much better after adding a few drops of pneumatic tool oil.

Ordered these bearings to get an old skateboard up and running. They're quiet and roll good.

Ordered the 100 pack. They come in tubes of 10 bearings each. No rust from what I can see. Bought to replace bearings from my vintage skateboard collection. Installation is easy just like any other bearing. Nice roll to these, normal bearing sounds. Functions as a bearing should. Excited to see how speed holds up through use.

Best bulk bearings I've found on Amazon. They might cost a little bit more, but they have good tolerances and run smoothly. Plus, they are freaking green dude... Like... Just buy them already. 😛If they see a lot of use, you might want to pull out one of the rubber seals and lube em. Factory pack is basically just rust prevention. Come in lil plastic sleeves and packaged nicely. Yo did I mention they're green? 💚

I used them solely for 3d printed projects. They seem to suffice so far for load bearing applications but do not seem to spin freely for say a fidget spinner.

They work great for out extra roller skating wheels. Easy to install and smooth rolling.

The very worst bearing I've ever encountered I have 6 year old bearings thats better than these smh..you def get what you pay for !!
