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

Los compré por 10 o 12 euros y me salieron muy bien. Usados en surfskate y dan buen rendimiento. Requieren bastante mantenimiento para evitar que giren mal por el polvo

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 2021I 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 2I am including a photo of two of the bearings, the others are already installed. I have no concerns at all with the bearing shields.
