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

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.

Nice bearings, hope they last

Daughter's stunt scooter was starting to sound very rough and harder to push. This was an easy swap to fix the problem and these bearings have been very quiet and nicely smooth.

Awesome fast bearings. Used these for quad skates. Although the sellers say they are pre-lubricated, it wasn't enough for skating needs. Washed them off with WD40, dried them and I fully oiled them, they did slow down a bit for me, but they still fast 🫶🏻 faster then other bearings I've had.

I wanted some low friction bearings for use in 3D printed models. This worked nicely in this pendulum setup I am working on to wind up my Accutron DNA watch ... which won't wind up in a conventional winder. I am now using these in other models. The ceramic bearings are lower friction than other bearings, hence they are ideal for fidget spinners and the like.

Used in my skates realy good bearings haven't let me down so far

My godmother bought me two of these packs (as my roller blades need 16 bearings). My blades are better than ever. I shall make more reviews (to say how long they last ext.) P.S. The packaging was great quality

Got mixed experience with these bearings, they came bone dry and although spinning very nicely and for long time they seem to be very noisy. Under load they don’t feel as frictionless as the previous brand I was using. I have added some lubricant and it seem to help to address noise issue for some but not all. I’ve done about 30 miles on them and they are noisier than my previous ones after a year of use (about 400 miles) and cleaning service. Price is good though and definitely better than full metal bearings, just not as good as other ceramic bearings I’ve been using in the past.

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.

Die Kugellager laufen beeindrucken leicht. Der Unterschied zu den herkömmlichen Stahlkugel lagern, ist beeindruckend.

This is how it looks like with and without the bearings.
