Great bearings for any type of skating, they last for ever if you clean them regularly. Probably the best bearings made and they're only $35.

OK, so I thought I had some 8 mm spacers from an old set of roller bones kicking around but they're actually 7. I've been searching online quad shops to no avail - where can a guy get some 8 mm spacers?

What is the standard bearing part number (i.e. 608, 207, 9104, etc), the standard inner diameter, and standard outter diameter for skateboard and rollerblade bearings?
Needing info...thanks.

you should be able to tighten them up, to avoid rattles,but yes you do end up with some of that same slop,i ordered a set with 7mm tophats,which you won't find in most shops. they're supposed to be for quads, they can be bored to 5/16 pretty easy,huh.I did find a tophat with a soft fit,too,that gives you play from two pointa in addition to the loosness in the bearing.

Am I correct in assuming that both of these systems have 8mm ID on the top hats? If so, it will be the same noisy, crappy fit on standard axles as 8mm bearings. I looked at the ABS at a local shop (I was shocked they actually had them), and they rattled badly when I put them on some trucks.

I had these bearings on my first board for two years never lubricated or cleaned them and they still rolled fast I loved them. I have been looking for another set but no body in sydney sells them. I loved them!!!

I decided to look at fafnir bearings just because I was curious...found some interesting pics for some bearing designs I've never seen before. Pretty cool stuff. this is their is their angular contact ball bearing.
Pretty cool.

more balls

(216.107.nnn.nnn)
the balls are smaller,you're right they might weigh more,you'd have to take the bearings apart to be that specific,bearing mass can be very important,the bearing race is several times as large as the ball,so each time the wheel goes around all the balls spin a few times,this ratio makes the weight of the balls more important,or rather any reduction in the weight.If all 8 balls weigh the same as regular 7 balls,they are still spinning on a smaller radius,the further out from the middle weight is the more it effects things,ball spin on their center and around the center of the axle.Hypothesize all we want,a real life test with different weight riders on a cosistant fast surface and enough rechecks,is the only way.

The weight of the ball bearings is nothing compared the the heavier wheel and hte larger flywheel effect of the wheel. Besides since you have 8 balls insead of 7 you might actually have more weight in rotation.
The advantage is simple. With a 7 ball bearing at any given time a maximum of three bearings are supporting the load. Take one out and look at it. Imagine the tolerances were very loose. You would see THAT IF THE BEARING WERE A CLOCK The all the balls at 9:15, 10, 11, 12, 1, 2,2:45 actually bear no weight so a maximum of three balls are supporting the weight at any given time.
With an 8 ball bearing wheel you will have a minimum of 4 balls supporting (only when two of them are at 3 and 9 oclock so you get to only count them as 1/2 bearings and of course you count the other three. But most of the time you have 4 balls supporting the load. Sounds like porn- hey well skateboarding was invented in california after all.
So 4 balls better than 3.

Hizzout,
Yes, the tophats on the siN bearings do make washer unnecessary... they are just the right size to only contact the inner portion of the bearings... HR

Very interesting,may have to check those out.Lighter weight would accellerate fast,but NOT roll longer,you can't have both.Well you can,but it has to be one of the many other variables coming into play,like your old bearings were worn or a little contaminated.That's like saying little wheel out accellerate and out speed big wheels,one is true,but you'd really shitty bearings in your big wheels to have the little wheel guy pull away down the road.

8 balled bearing

Herbn,
I picked these up from flexdex to put on a board for my girlfriend.
While they claim more balls make you accelerate faster, and coast longer with less effort, I only find the latter to be slightly true. Yeah I roll a little longer per push it seems, but really it's not THAT much of a difference.
I was thinking of buying a pair of the SiN bearings. I've actually never seen the tophat that SiN uses before...I assume this eliminates the need for speed washers?? Correct me if I'm wrong.
Thanks for the info...
Peace

More balls

8? what kind of bearings are those? More bearings distribute load more evenly,they seem quite a lot lighter,and even in unbiased industrial specifications they have very similar load capacities to a 608.The perfect wheel would probabely have three bearings ;a very light ceramic needle bearing with maybe 5 or 6 needle rollers,centered in the core ,maybe spinning on a precision ground spacer this bearing is centered, unsealed and carries most of the weight.An outer bearing,perhaps a nine ball (sin type) or a minimiser, keeps things together as far as general misc loads , an inner bearing that takes the abusive poundings from the core directly to the hanger,a thrust bearing.All bearings could be on swiss steel races,and a little research or experimentation could establish pretty quickly whether/where ceramic balls or rollers could be used.The needle bearings could actually be quite narrow and small,not at all like a needle bearing in motorcycle swingarms,or some bicycle bottombrackets.All bearings handle the loads the way they were designed to,so over build could be minimal,speed would therefor be "maximal":)

speed washers/bearings

FYI --
In my last flow package from East Coast Skateboards, Jamie sent me a bunch of coned speed washers. These are not a kind I've ever seen before. They are very conical, about the same thickness as the little speed rings most people are using, but a bit wider across the face of the washer to allow the proper cone effect.
Anyway, I tried 'em on a set of wheels last night -- some newschool wheels (normally not easy to get a proper setup with), and they worked great.

I posted a similar question a while ago, and never really got an answer....but I'll try again.
What is the advantage/disadvantage to having more balls per bearing? Most bearings have 7 right? I've recently bought a pair with 8, and now I notice that the Sin Systems bearings have 9. What's the purpose?

he Ultimate Bearing

(63.118.nnn.nnn)
The Ultimate Bearing would be larger than standard 608 bearings. They would be designed to handle thrust loads like a tapered roller bearing as opposed to a ball bearing.
They would have tight tolerences and have triple seals to keep dirt out as well as accept a cool through the axle cleaning system to keep them running longer. They would have brass cages to help dispate heat better.
They would come with extra shields in case you bent one shield while cleaning them.

cheap and fast

A lot of new bearings seem slow and crappy, but it's usually just because of the thick, cheap lube. The cheapest halos, which are like $8, $10 at most a set locally, have this thick gel goo which makes them soooo slow. On a hunch I bought a few sets, cleaned out the lube with de-solv-it, and put in my own triflow- and I was surprised at how well they worked. On my 70mm green kryptos they seemed as fast as bones reds, certainly fast enough, these halos with the red metal removable shields are abec-1, which shows you how abec is worthless for rating skate bearings.

Anyone ever heard of these? I just bought them and have yet to ride them (waiting for new wheels to arrive from SolidSkate). Still trying to figure out the truth from the bullshit about abec ratings. I want to go faster so I went up to 5's, but I hear tell that abec3's are actually better. So whats the real story and why?

Spent some time on these bearings over the weekend... found them to be smooth... they accelerate well and seem to hold their speed well too.
I consider these as a worth addition to my aresonal... HR

Spin test

While there my be bearings that don't spin in your fingers when they're new,heavy oil,grease,whatever. But i've yet to find quick smooth bearings,out of the wheel that were not quick in the wheels.Heavy oiled or greased bearings need to be broken in to show their speed,a lot of people get bearings dirty before they're broken in,so the potential speed is never realized.As an example of a spin test that works,take clear sheild abec5 Speedemons,and Gold sheild (also ABEC5) Speedemons,the gold spin a few times in your fingers,clears don't,they just drag to a stop in less than one revolution,call World, they'll tell you the bearings are identical except for the sheilds,when confronted,"ok the oil may be thicker" but guess what?On their best day Clearsheilds are crap and the golds are a usable quick bearing,that's cheap and is therefore easy on the wallet to replace often,new bearings rule! beavis,ohhh fer shure!All the better bearings,Both powells,reflexs,ninjas, spin well in your fingers,if you're looking for fast really cheap bearings whose speed is masked by thick long lasting lube, good luck!,you'll have ride a lot of duds before you find one that breaks in a spins. Nineballs don't spin all that much,but that's the light weight,of the races and balls, less momentum,you can still tell they're gonna be acceptably fast ,with the finger test,on the road they're real fast.
