16PCS 608RS Blue Skate and Skateboard Metal Wheel Bearings – ABEC 9 Rated – Great for Speed - Skateboards, Inline, Roller Skates, Scooter, Longboard Wheels

The delivery was extremely fast. It was well packaged and very good value for money. These were bought for a school project. Budget was a massive issue. These Abec 9 were excellent value for money. The fit is good and just need to be pushed in with no special tools. The bearings all roll smoothly with limited friction. Would buy again.

Recently bought some rollerblades for going around the village in, but I found the bearings were all rusting as they were not waterproof; I decided to buy these bearings, put them in and so far have not seen any problems. They are waterproof and dustproof, meaning I can roll around my village without having any worries of them rusting. The only thing I would say is that my skates don't roll for as long (in other terms, these bearings decelerate slightly faster than my previous ones) but this is only very minor and doesn't actually make much of a difference. For only £10, these are great.

Very durable and easy to use

Delivery was very quick however 2 of the 16 lot of bearings was making a horrible noise when I spun it. They are all pre lubricated so I don't know why 2 of them has a noise like the bearings inside was almost dead.. The other 14 was perfect.. its a shame as this order would be perfect if these 2 weren't messed up 😔 Its not the sellers fault.. I just seem to be unlucky.

I bought these bearings for a pair of quad roller skates. I've not used them that much yet as I only recently bought them but they seem to run smoothly enough. They have removable shields for easy cleaning again something I haven't needed to do yet. I doubt they would be very water resistant but they are not designed to be. To sum up they work well and are good value for money. I would buy them again.

These ain't "frictionless". They don't free-spin if you hold the middle of one in your fingers and flick the outside - it stops pretty much immediately. They feel fairly smooth but possibly packed with very heavy grease, maybe? I picked these up for various 3d printing projects; I will probably get some more expensive "faster" ones as well, so I can choose between Cheap and Good as the task requires. They will probably suffice for kids scooters and suchlike, where you're not fussed about letting them get up to high speeds. Likely not well suited to skateboards or other applications where you want the lowest possible rolling resistance to maximise speed.

huge improvement over the old bearings that came with the skates. my son is literally twice as fast on them now!!

Cheep alternative for scooters and skateboards. As there left out in the rain it's better than buying branded ones. As the rain ruins them just as fast despite the price.
