Senston Ceramic Skateboard Bearings High Speed Double Shielded 608 RS ABEC-11 8 Pack Set for Skateboard Trucks Scooters Wheel Roller Skate

I bought these for a non-skateboard project I'm 3D printing. For this project I needed bearings with very little drag or resistance to movement - the most free-running bearings I could find. They also need to be able to run at high speed. Well, after trying these, I just bought some more of them. They are incredibly smooth. Smoothest 608 bearings with the least amount of running resistance I've ever encountered. They're a little pricier, but if you want to minimize friction losses, it'd be hard to beat these, especially for the price.

The media could not be loaded. I had some regular 608zz bearings that I would disassemble and “degrease” for smoother filament rolling, but these work fantastic right out of the box. There is a little more play in the bearings compared to a standard greased one, but it doesn’t seem to be a problem for my filament rollers. I highly recommend them.

Product was as described and on time.

You can literally grab these bearings between your fingers and spin them a couple times against your palm and then set them flat on your finger and every single one of them will spin virtually silently after just a slight bit of even just rotating to wear them in for like 3 minutes with no wheel attached sometimes even longer I have one bearing that only spins about 2 minutes and 20 seconds oh how terrible LOL not this is truly amazing it reminds me of the really really good German made lucky ceramics that were around for a while with the white ISO balls and the type of raceways you see on longboards yet with larger ball size so you get more give and more strength at the same time for side stuff so it's really good cuz I write a lot of transition skating with old school boards and kick tail longboards and stuff or I do all these and grinds mostly including grinding on to things and onto things and then 180 off and stuff like that and doing old school tricks so I use a lot of interesting hardware and honestly I just don't like the shield color it's just not my thing but it's a great looking bearing and then the right setup will be perfect anything with a black and red mode if or like a gunmetal and red. Most of my stuff tends to be green in color or orange for purple maybe even or black and silver or black and green etc. I was just absolutely blown away with the qualities bearings they seriously from The limited use I have and considering I was a sponsored skater like three companies for many years on amateur teams as well as writing flow for many months for some major labels and having brief stints on teams so I've been around I may not be an amazing professional skateboarder but I'm a damn good amateur skater that's very comfortable on a wide variety of decks and I'll tell you these bearings are incredible it'll be interesting to see how they hold up. Right now there is no better deal on the market in my opinion unless you want to spend over $600 to get bearings that do this and I'm not exaggerating and I hate to say this but bones really needs to get with the times because their stuff is just pretty much all really good but it's not much different so I think being really much different in some way is like acceleration cruising and strength etc amongst the models and why even by the original when they're all made the same specifications in the same mass amounts it makes me sad to say because I'm going to such a good go-to but they're so overpriced it's ridiculous they're ceramic bearings should cost like 20 bucks these should be like 80 it should be the max for like bearings of this however however they are the iso white ceramic titanium alloy balls which is very very rare and I did actually even test one of them

My current long board bearings would spin for 1minute 59 seconds these new bearings spin over 5 minutes. I weigh 225lbs and they are still fast with my weight.

Was excited to find a cheap ceramic bearing after paying many times more for Swiss ceramics. Out of the package they spun really well.However they are super fragile. My 100lb kid broke 2 of them on the first trip to the skate park. Luckily he was fully padded as he slammed pretty hard. First bearings I have ever seen actually break.Might work well for low impact applications but do not reccomend for skating of any kind.

The media could not be loaded. Was hesitant to get these cuz it only had like 4 reviews. Glad i took a chance cuz they were super fast right out the package. Would buy again for sure!
