"all right ,so many geniuses have come on here and said things like "abec means nothing to a skateboarder" "
It doesn't take a "genius" to know this. Any other industry that uses bearings doesn't care about ABEC ratings unless they're dealing with speeds over 30,000 RPM. In my job's case, we're more concerned with the factors like the loads they'll be subjected to. We might use the same size bearing for several different applications, but those bearings are not the same internally, even though they're all ABEC 1s. Ever seen how many variations of 608s are offered by the major manufacturers, even with the same ABEC rating?
"hmmm instead of telling me what abec ratings DON'T take into account, tell me what abec DOES take into account. There is not a whole lot of other things going on in a bearing,i would guess that you don't really get what and why abec ratings work more often than not,"
OK. What the ABEC ratings take into account are tolerances like how close (for a 608) to 8mm the inner bore is, how close to 22mm the outer race diameter is, and how close to 7mm the width is. And the allowable variance between an ABEC1 and an ABEC 9? About .0002" on the diameters, and .004" in the width. Think your axles and wheels' bearing seats are precise enough to where that will make a difference?
To oversimplify, what the ABEC ratings tell you is how precisely it'll fit into whatever you're mounting it in, and how balanced the bearing is, and therefore how fast it'll spin before it becomes unstable.
"most of the time a 7 will be faster than a 5 and definitely faster than a 3 or 1."
And you're basing this on...? First of all, how do you actually know what the ABEC ratings are? Most bearings sold for skating do not meet their claimed ratings (as tested by California Bearing). And many of the better bearings, like Rockets, Bones, and Oust, don't even use or advertise ABEC ratings.
Your argument also seems to assume that a company's various rated bearings are otherwise exactly the same, except for that slight difference in tolerances. Could it be possible, for example, that Brand X's "ABEC 1" is the cheapest Chinese bearing that they can find, their "ABEC 5" (which still may only be an ABEC 1) is a little better, in design and/or materials, and their "ABEC 7" (still possibly only an ABEC 1) is better still?
And 2 bearings built to the exact same tolerances can still perform differently, just by changing the materials. A perfect example here is Rockets. The steel and ceramic models are the same, except for the balls. Same races, same retainer, same seals, and most importantly, same ABEC rating. But by changing just the ball material, you change the performance.
"but if you had a better rating system,clue us in"
Rockets, Oust, and Bones already figured that one out. You use a design optimized for skating, use quality materials, and screw the ABEC rating...

i usually just use a dilluted rubbing alchohol to get the crap off then lube em up with bones speed cream. i have a feeling the dilluted alchohol night not be good although it's served me well so far. but on to my question- i've heard about 'dry lubes' like graphite? could someone explain all this for me and offer their opinions about it? thanks!

that's along time,if your bearings feel shot, even after being freshly "lubed" with liquid wrench, then you need new bearings in your bearings to make them feel like new. I just use triflon for one or two relubing,i keep things dry(no rain rides) and try to avoid offroad excursions,bearings can last years,especially if you have a few boards. Buying new bearings is actually a cool thing, try to lube up an old set of bearings, then replace them, you keep them as "spares" ,generally the new bearings are so much better you never go back.

allright i have a questions i have always used this stuff called liquid wrench to clean my bearings and now find out that it is like wd-40 and it takes all the good oils out of the bearings to make them faster and i have bones super swiss and i was wondering what would be the best stuff to put in my bearings to get them back to new with the oils???

all right ,so many geniuses have come on here and said things like "abec means nothing to a skateboarder" ,"Quality of materials,design,lubrication,and surface finnish are determining factors to how fast a skate bearing is" abec takes none of these into account. hmmm instead of telling me what abec ratings DON'T take into account, tell me what abec DOES take into account. There is not a whole lot of other things going on in a bearing,i would guess that you don't really get what and why abec ratings work more often than not,most of the time a 7 will be faster than a 5 and definitely faster than a 3 or 1. For instance if the abec rating uses a sound level,that may seem like it's not measuring those critical factors,or is it? A quiet bearing is well polished, a quiet bearing is probabely made out of a quality material because it takes a quality steel with no voids to consistantly acheive that fine polish that makes the bearing quiet.A bearing capable of spinning at 30,000 rpm,may be over kill ,no 200mph skateboards, speed ratings of that kind,say things about polish,material quality,lube,and design. ABEC ratings are perhaps a bit indirect and certain variables might just every now and then make a quiet bearing slower than a noisy bearing,but if you had a better rating system,clue us in and maybe we'll use the MSKBEC rating system.

"For skateboarders' an ABEC rating of 7 or 9 is good for speed."
ABEC 7 or 9 is good for medical and dental equipment. For skaters, its meaningless.
From minibearings.com's bearing FAQ:
"What is the purpose of higher precision bearings?
Higher precision bearings are designed to allow high precision machinery to operate smoother and sometimes at higher speeds than a standard bearing would allow. Keeping this in mind, a standard ABEC1 608ZZ is rated with a limiting speed of 32,000 RPM with grease lubrication and 38,000 RPM with oil lubrication. The actual speed that the bearing will attain without failure also depends on the loads applied and other running conditions but there is really no need to go into that too heavily here.
We feel that we must stress here that the purpose of higher precision bearings IS NOT TO GO FASTER, but (amongst other things) to ALLOW HIGH SPEED MACHINERY TO OPERATE AT FASTER SPEEDS THAN STANDARD BEARINGS WILL ALLOW."
Quality of materials, design, lubricant, and surface finish are the factors that determine how fast skate bearings are, none of which are taken into account by the ABEC rating. When you buy a bearing rated higher than ABEC 1, what you're getting is a bearing that can spin smoothly at speeds higher than 32,000-38,000 RPM, which would be over 200 MPH for most skateboards...

top end bearing differences

what happened to the defenders of oust? a year or so ago all you had to do was hint that ousts may not be all that, and they attacked,oh well i guess we bought'em and oust is launched. Well not that they're bad, my grippins with the nines seem to have the best combination of quick accelleration and momentum than any other wheel/bearing combo i've tried. The biggest difference in top end bearing performance seems to be the retainer,if that plastic don't crack ,that's a great bearing.

A guy who posted that the abec number is the number of ball bearings is saying that I posted "junk"? Give me a break.
Rockets and Bones are pretty much the standards for fast, long lasting skate bearings and neither care about Abec ratings. There are other bearing marketers who do state an abec rating on their bearings (whether their chinese factories are actually making the abec level they claim or not is another question), and some of them are also good bearings. Some of them are absolute junk, too.

Slim,
You are mostly correct, the ABEC rating does refer to tolerance, the other junk you included does not exactly apply. For skateboarders' an ABEC rating of 7 or 9 is good for speed.

I have a couple of sets of Biltin bearings; one set is ABEC 5 and one set is ABEC 7. I have never cleaned or lubed them. They still run fine but at some point I think I should clean and lube them. Any recommendations on the best process? Thanks. Rob O in Newport RI

the new labyrinth series bones is making is them playing catch-up! ron and ninja have been using designs like these for awhile now. as far as bones is concerned, the speed higherarchy remains the same, labyrinth or not (reds->swiss->super6->ceramics). if you're stuck on bones i'd go with the original super6.

speaking of retainers, i noticed that my oust9's were a bit dry today so i went wheel by wheel and took out the bearings(not disassembling them) a lifted the sheilds, trifloed them,and damn, i think about three of the bearing seperaters ,retainers, had cracks in them. This sort of sucks,i mean my boards just roll in the street they don't fly off ramps or bounce off coping and land on the flatbottom.Could retainers actually break from cracks and seams between concrete,and asphalt,like at the base of a driveway cut where it meets the street.The bearing still seem to roll fine but when i replace them maybe i should just go back to cheap gold speedemon oiled abec 7.

you need 2mm balls,i guess you got that part, a source for bearings. I wouldn't just get the cheapest ceramic bearings and swap out the races,get good ceramic balls from an established bearing manufacturer,not related to the skateboard industry at all, except maybe as a supplier. You may need to buy a 100 or even a 1000. I've found that my thumb is just the right size,if i take the outer race and put it on the finger print part of my thumbwith a bit of presure it sort of plugs the hole and squeezes in a bit so i can put the bearings in the race and they will stay out in the channel. All the balls need to be in a row ,then you can sort of manuver the inner race around them,into the middle of the bearing. Trap the balls in the channel and your home,just seperate the bearings evenly, and snap the retainer in.

dude, the number in the abec rating is not the number of balls in the bearing! Abec is a standard for the tolerance in bearing (probably things like how perfectly round surfaces are, how big the gaps are, etc.). It's basically a worthless spec for a low-speed application like skateboards. Please read some more before spreading misinformation. Here's a link for newbies: http://www.skateboard.com/Frontside/Skatelife/Features/ABEC/default.asp

I ride slalom and I have an extra set of super precision ceramic sealed bearings for sale. They are abec9, not the brand abec, just refering to the number of ball bearings. These are American made. I've been very pleased with the set I have, I just have an extra set I need to sell.
If you're interested please email me at taikinney@hotmail.com
Also I will pay shipping for lower 48 states!

ron's are fanastic for street skating, in fact vert skating is what they were designed for. i'm surprised to hear you thought the super six were slower than the regular swiss- maybe so for street skating (acceleration), but for downhill the supers have a noticeable higher top speed. remember also that bearings do seem to get faster as you use them a bit after they're new. swiss (regular,super,ceramic) are all great for downhill and rons are great for street. i've been wanting to try pleasre tools ceramics- what does everyone think about those compared to other ceramics?

ok so ive been riding the bones swiss for quite a while now and im wanting to get something else, but im not sure of what to get i tried the Bones Swiss 6 balls a while back and didnt like them as a matter of fact they were slower than my regular swiss so i was thinking about getting some Rockin' Ron's Ceramic bearings but im not sure about how they would last against street skating because i do that as well as skate ditches so any input on what company i should go with would be appreciated
thanks
