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

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

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.

Product was as described and on time.

Great Value, Smooth Ride, Durable, Rotational Speed Is Impressive, Easy To Install

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.

I initially loved them and was so excited to find and try affordable ceramic bearings! They spun for several minutes and were so smooth and fast. Sadly, after only 3 months of derby skating, several are seizing up and failing and I’m having to swap them out before my bout this weekend. I’ve also put them in wheels I intended on using at the skate park, but will probably go ahead and swap to a more reliable metal ball bearing to avoid failure. I’m past the window for returns so keep this in mind if you’re an aggressive skater. No one else seemed to have this kind of problem so maybe it’s a fluke? I’m definitely bummed.

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.

I'm very pleased with these bearings! Came quickly, nice packaging and slick for outdoor skating! Will definitely buy again pending how long they last only thing I have to wait to review on.

Really surprised at how well these bearings spun when opening the packet. I put them in a set of spitfire 97a formula four 54mm full conicals, and tried them out at the local skatepark. They did not feel any different from my normal bearings, I use "Old Boy Ceramics" normally, which sadly don't seem to be available right now, so I tried these out, and they are half the price of the Old boy bearings. To my surprise, they seem good. I did notice that the plastic rubber seals don't fit as well, so time will tell how durable these bearings are. Will try to make an update to this review if they fail quickly. But right now they seem like a genuine bargain.

Fonctionnent très bien.

Update on May 27 2023: I have now put over 800 km on my scooter with these bearings, with no servicing whatsoever ( except for packing the bearings with grease when first received). The bearings are smooth and quiet with no sign of sideplay, or leaking grease, and run great, just like when I first installed them. I am completely satisfied with these bearings. Original Review June 2021 I received these bearings a few days ago and installed them in my scooter wheels. I was replacing the original non-servicable scooter wheel bearings, so I thought I would try these ceramic bearings. This is my first bearing replacement so I don't have a lot of prior performance to compare with. The bearings arrived quickly, and are as the seller describes. Each bearing has two red rubber covered shields. Each bearing consists of 7 white ceramic balls in a cage.The bearings rotate smoothly in my hands, no rumble or catches. I decided to lubricate the bearings with grease, as I wish to maximize time between bearing servicing, rather than using oil to get maximum speed but needing more frequent lubrication/servicing. Just to be clear, these bearings are what is known as "SEMI-CERAMIC", which means that the balls are indeed ceramic, but the races are steel. Lubrication can help to protect the steel races from corrosion, and prolong the life of the bearing. I am happy to have very slightly more drag from the grease, WHEN THE BEARING IS UNDER LOAD, as opposed to oil lubrication, for the advantage of longer time between routine bearing maintenance. I have run the bearings now for about 30 km, they are running smoothly, quietly, and I am happy with them. If I have any problems with them, I will update this review. Presently, in June, I give these bearings 5 stars. UPDATE JULY 2 I am including a photo of two of the bearings, the others are already installed. I have no concerns at all with the bearing shields.

Sind echt schnell und rollen verdammt lange. Sind nur leider von anfang an sehr laut. Benutze sie jetzt ca 3-4 wochen ist eigentlich noch zu früh um was darüber zu sagen aber ich bin bisher sehr zufrieden. Vorallem bei dem preis. Benutze sie zum streetskaten. (Skateboard)
