Bearings with 8 balls...the pros & Cons?

My style of riding (mostly flats, and some hills) never usually requires I have super-speedy bearings, or any really technical bearings. If they roll long enough for me to pull out some serious carves, they're fine with me.
So what are the pros or cons to bearings like these that have 8 balls in them, as opposed to 7? Does it really make that much of a difference in speed or effort?
Just curious.

Refers to a coating/plating on the bearings,the ABS have snaprings holding the shields on,the SINS are probabely the same deal.Lubing is the same as any other bearing.Since the balls are smaller, they have a lower mass but the speed they turn is higher,overall effect,havn't run mine fast yet,but i have given up on the search for the fountain of incredible speed gains,so they'll probabely be close to other top quality bearings,and that's pretty good.

How can these bearings be serviced? The pictures I've seen don't show a side that's open. And, are they lubed with something thin, or is it grease?

Lock Up

I don't think a lock-up or seize of the bearing is very likely. By locking-up I'm assuming you mean to seize as in a combustible engine, which the extreme friction would cause due to lack of oil. The only way I see it happening would be if the bearings rusted, maybe after sitting long-term with no lube....still not likely. But then again, maybe someone has encoutered this.

Bearing Cleaning

Ricky, I'm not certain about your snap ring question...to remove the shields from my bearings I just use a sharp edge of something. On cleaning, there are thousands upon thousands of different products to clean and lube with...the good news is that for 99.9% of the time you can find all you need at the local Wal-Mart. To clean out the bearing I use plain old brakes part cleaner. It is usually less than 2$ a can at Wal-Mart. Spay out the bearing really well to remove dirt, grime, grease, etc. This is a fairly volatile liquid so it should dry very fast. Now just lubricate. 3in1 oil is available just about anywhere and penetrates very well if by chance you can't get the shield off. Silicone based lubes work well too and can be found at Wal-Mart. Gun oil, which you guessed it, can be found at Wal-Mart and works well too. I would not however recommend cleaning or lubing with WD-40. It won't break down the old grease and I find WD-40 has a terrible tendency to gum up when used as a lube. Good luck, feel free to shoot me any questions you have. Brian

I thought i was gonna use them in a set of springy lively Sector 9 wheels,then i realized i had a set of Aluminators,red 78a,already set a side,and Rene told me they fit perfect,perhaps more perfect in the aluminators.So i swapped stuff over,i probabely do like the Aluminators a bit more,the eternal 14 year old in me loves just the idea of having "mags" on my skateboard,regardless of the technical advantages.In all the assembly and disassembly i found one adaptor that's just a bit looser to the bearing,if you have play between the adaptors and the bearings+the tiny bit to the axle,it's minor way less than a regular set up but a little step down from my 8mm to let's say a set of ninja's.I don't like that the adaptors are bored 8mm,They make them for quad skates (7mm) i think i'll get those and bore them to 5/16,i love my lathe:)

Beyond the breach.
The only thing harder is a diamond, which is what is used to grind and polish the balls in a "one week" process. The silicon nitride balls are impervious to oxidation, chemicals, require essentially no lubricant, and result in a bearing that will outlast a conventional by a factor of ten times.

I need to know if there really is a difference in the China and Swiss bearings, I know they're made in different countries but is there a difference in quality?

19.95,the aluminum shims are silver,is this a raw aluminum?for what it's worth black anodize costs something and oxidation of aluminum causes powder/right by your bearings,ehh long shot.More annoying to me is the spacers are 8mm bore aaarrrghhh! they fit nice into the bearings they could fit almost that tight on 5/16 axle, then we'd have something, but they DIDN'T do that,so they need side tension lose the play,,double aaaaaarrrrgggggghhhhh!!

Ok, so I just got done looking at the Sin bearings at Longskate, and two minutes befor that, I was looking at the ABS bearings on the reflex site. Anyone, anyone, anyone?
Oh and cheers to all!

I put SiN (Silicon Nitrate) bearings in a new pair of Aluminators, aligned up pretty good and spun well. But I have not been able to ride them more than just a couple of test rides. It's seems faster than what was on before (Swiss Bones and worn down Aluminators), but hard to tell, could also be wheel differences. What I would like to do is some speed runs with others, change bearings, and see if there is any difference. Have not rode fast in a while, start to itch for some aero.

Bearing Cleaning

Alright, let me show my ignorance here.
What type of tool or whatever do you use to get the little snap ring out to remove the dust shield from bearings?
Also, I know there are many opinions on the best lube for bearings, but just give me the name of something that works well and is easy to find at a hardware store or somewhere like that. I'm limited in this city on skateshops that would carry any skate bearing specific lubes.
Do I clean the bearings with a blast of WD40, then clean that out, then use the lube and close them back up? Give me some info on best practices for cleaning.
Thanks for the help!

Come on now, Bones bearings are PACKAGED for skateboarding, with seals made to order (logo & stuff). I'm sure the bearings come right off the line, China or Swiss, along with millions of other customer bearings. ABEC ratings exist so specifying engineers can choose the tolerances needed for a particular application.

Pepe,
Bones bearings are made for skateboarding and hence don't need no stinkin' abec. Retailers seem to need bearings to have abec ratings, as that's what they're always harping about, but the only thing you or I need to worry about is that they aren't grease-filled and can be opened for servicing on at least one side.

on the bottom of the axle are probabely not from spinning bearings, just from vibrations from the road graininess,which would probabely still happen because of the 5/16 axle,8mm bearing thang,even with spacers.

Red hot spacer up the juxy

Herb,
The scorn we are expressing is for people that encourage others to leave the spacers out. There is no reason to say that bearing spacers aren’t neccessary, other than to mess up the person that’s listening. It’s quite common in situations where one person is trying to convince another to buy something (recall the last line of the poster’s message “ride with pride, Sector9”).
Bob,
If you look at some trucks, you can see slight marks worn onto the bottom of the axle from the bearings. As you can probably determine, these marks are from the weight of the rider forcing the bearings to rub the axles. I don’t worry about this since the axle is really just a post to hold the bearings with, rather than something that comes in contact with a moving part.
