Amphetamine Skateboard Speed Bearings - Set of 8 - Choose From Ceramic, Stainless Steel, Abec 5, 7 - Fits all Skateboard Wheels - Pre-Lubricated

Right out of the box they had a lot of oil. When I would try and spin the bearing, it would spin once and stop. Quickly washed in isopropyl because I wasn’t very satisfied and hoped it would get rid of some of the oil. Worked great, easily the best lower end ceramics around. I don’t care if my bearings are silent or not, but these are dead silent so I was surprised.

Other hybrids that cost more doesn’t do more and is more fragile with the covers. A little rough ride and the covers are dented.

I used them in a walker, they fit perfectly

SUPER FAST!!!! Take off the shields with a knife and give them a good 5 minute wash in some nail polish remover, and they will spin forever. The only problem is the non-removable shields on the bearings (you can take them off with a knife). I cut my finger on my knife while trying to get them off.

Initially I bought ceramic bearings made by Panther but ended up returning them after trying them because they were no better than cheap, no name steel bearings I already owned.I didn't have high expectations getting Amphetamine bearings because they were even cheaper. However, after trying these bearings I was pleasantly surprised. After the break in period of several hours, they are awesome. These made riding my board a very pleasant experience. There is a very noticeable improvement in speed and ride quality over steel bearings.I use these in my longboard. Cleaned them in 91% isopropyl alcohol and lightly lubricated then with Singer sewing machine oil. They are super fast, very smooth and quiet.Don't judge the quality of these by the free spin time. On their own, they don't spin for very long. Probably as long as steel bearings. Under load, they roll forever though.The one negative, that's not really anything to do with functionality, has to do with cosmetic appearance. The print on the outer shield (no inner shield on these) wears off really quickly. I've only cleaned these once and there print has effectively worn off to the point where you can't tell what brand these are. If that's something that's important to you, it will probably benefit from a clear coat of some kind, like clear nail polish or something.Overall, for the performance, I highly recommend the Gold version of these bearings. I'll get another set of these when I put together another board.

Good for the price was didn't know you need to buy washers for them.

I used to ride bones reds, not any more.These are just as nice without the price.I can buy 2 sets of these for the price of reds and be completely happy!I've had friends try them, letting them they're reds, to finish a session and learn they're 8 dollar bearings.Highly recommend to anymore looking for extra or replace bearings.

The media could not be loaded.  These things are actually really good and they spin for a VERY long time after you degrease them. I'm using them for a fidget/spinner toy so there won't be any load on the bearing so I don't need any extra gunk slowing the bearing down. I attached a video of it after it was all cleaned. The first bearing spun was a regular bearing and the second was the ceramic bearing.

If you're looking for bearings to use in your 3d print projects, these are what you need.I had zero defective bearings in the box, and they're super smooth, almost no torque required to turn them...you need these in your drawer!

Muy buena velocidad, giran muy bien y prácticamente sin ningún sonido. Cada salida giran mejor. El precio sin duda es el más competitivo. En una prueba con otra tabla giran más tiempo que mis Reds.

Die Teile sind der Knaller! Ich habe die Bearings für den Roller meiner Tochter gekauft. Sie hat die Teile ein paar KM eingefahren und nun laufen sie super leicht und schnell. Ich würde sagen aus meiner Erfahrung von früher, das sie sogar ein wenig schneller und ruhiger laufen als die Reds von Bones. Nun hat sie sogar noch 4 Stück auf Reserve! Absolute Kaufempfehlung!

Da ich mit meinem Longboard jeden Tag zur Arbeit fahre, ungeachtet welche Wetterbedingungen herrschen, war ich auf der Suche nach "wetterfesten" Kugellagern.Einen Langzeittest konnte ich leider noch nicht machen, aber mit diesen Kugellagern rollt mein Board um Welten entspannter.Wenn man die Rollen mit der Hand dreht, rollen sie tatsächlich langsamer als andere aber jeder der sich mal ein bischen mit dem Thema Kugellager auseinander gesetzt hat, weiss das dies nichts über die Eigenschaften eines Lagers aussagt.Ich hatte gestern auf jeden Fall dank dieser Kugellager meinen ersten "Boardgasmus".Bin über einen leeren Supermarktparkplatz gerollt und mit diesen Kugellagern bin ich nur so davongerollt.Klare Kaufempfehlung, vorallem zu dem Preis.

These seem good. Smooth and quiet.
