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.

The media could not be loaded. 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.

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.

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.

Nice bearings, hope they last

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

Very well made and smooth bearings. Used in a combat robot as rotating weapon bearing. Took a great deal of punishment.

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.
