bearing + high abec+= same as low abecs

[Knickfan1221]

is there really a difference between the speeds of higher abecs (such as abec 7 and 5) and lower ones like (3 and 1)? and wut are bone reds considered?

[teh_awesomness]

reds are abec 5 i think and higher abec ratings are supposed to be faster but arnt consistant and differ between manufacturers.

[fatal hussein]

I used to have Red Bones and now I have Speed Metals... the only difference is... well... I can't really tell the difference actually. The Bones felt a little smoother at higher speeds though.

[DazedAndConfused]

Reds are ABEC 1. Even if skate bearings didn't lie about their ABECs, they would be the same if everything except the ABEC where the same (same cage, and some other things that could make it faster or slower).

[BertlemanSlidesRule13]

No, Redz aren't Abec 1's, they are higher than nines. I know that doesn't mean how fast they go, but Redz have much higher tolerances that any bearings

[phish]

abec doesnt matter i have 3s from a local shop and theyre better than my nines

[DazedAndConfused]

No, Redz aren't Abec 1's, they are higher than nines. I know that doesn't mean how fast they go, but Redz have much higher tolerances that any bearings

For one, there is no Abec rating higher than 9, and two, all bearings made in China are Abec 1, including Reds.

[flipguy]

i no that bone swis are good bearing tho

[Marevix]

Abec makes no difference. It's a tolerance measure for industrial machines that rotate at over 50 miles per hour. It won't effect your skating.

so ur sayin that becuz a bearing is made in china it goes slower?

well thats stupid, metals dont really differ between countries like wood does

ABEC duznt mean mcuh anyway

It's not the quality of the metal, it's how smooth the finish of the bearings is. China has no laws saying you can't market something as something it is not not, and will put anything on the bearing if you buy 5000 of them. So they aren't concerned with quality, and just try to put out more and more bearings. So if any one has had numerous sets of Reds, and the different sets seem to have different problems, you now know why.

I have even had a set of Reds with balls that were too big, and it wouldn't spin well.

[Texas_Pete]

Reds do not have an official abec rating the corporation never adopted the abec rating system so they have no official abec rating... also the abec rating system is a test on the bearing, the bearing is ran at a set speed for multiple hours and then gauged as to how the bearing's quality is after the test. The higher the rating number the better the lifetime/durability/quality or whatever you could presume it to be

[Texas_Pete]

...and yes there are abec 9 bearings

ok ok ill give u that

but still, u cant say that ALL bearings are like that, im sure there are sum decent companies/bearings out there(i.e. bones reds)...besides there havta be some that come out right if they all come out different

and i have like 4 sets of ABEC 1s frum shit boards n stuff my friends have given me, defidently not the same speed as my friends Reds

I'm just saying what I have been told. Rockin' Ron posted this information on concretedisciples.com several years ago, before he came out with his bearings.

Probably the only reason Reds are faster than other China bearings is because they have a non-metallic ball cage. If you try a bearing with a metallic ball cage, then switch to Reds, you are likely to think they are better quality.

Texas Pete, I never said there is no ABEC 9. I said there is nothing higher than ABEC 9.

[Knickfan1221]

wut is a metalic or non metalic ball cage?

[DazedAndConfused]

Metalic is a metal cage, and non-metallic is a cage that isn't metal. Some non-metalallic cages are made from plastic and nylon. I know there is at least one other type of material (the type in Rockets) but I don't know what it is.

Basically, metallic is slower, and non-metallic is faster.

[unwanted hero]

dont even argue about abec its all about what company makes them

[yEa_I_skAte]

you guys aer pissing me off with the way u think u know ur bearings...i know for a fact that there is no ABEC fucking rating on bones reds...their company (bones) is confident and consistent enough to need a rating!

We here's what I've learned. I am a bearing engineer of almost 20 years dealing with miniature bearings for skate, aircraft, aerospace, and NASA applications dealing with all aspects of design, and ABEC specification. More recently my nephew and I started our own High Tech Bearing Company six months ago, Ok enough bullshit. The ABEC is the allowable tolerance. The ABEC 1 tolerance for the bore of a 608 bearing is .3150" +.0000 / -.0003".==== that means the Bore could be anywhere from .3147-.3150" (8MM). ==== ABEC 7 is .3150 +.0000 / -.0002. (.3148-.3150) What does all this mean??? The Abec tolerance is all but INSIGNIFICANT in a skate application. Skateboard Truck Axels are not manufactured to the same tight tolerances as the Bearing. And the O.D. of the Bearing goes in a flexible urathane wheel. This eliminates any possible advantage of the Abec tolerance would give to assure accurate fit. The Abec is the DIMENTIONAL TOLERANCES. The Abec tolerance does cover out of roundness and for this reason I would use ABEC 3 or better. Almost any bearing with the country of origin on the bearing except for china will be Abec 3 or better. Back in the 80's they had to sort bearing lots to get the Abec 3 and Abec 7 Bearings. Todays modern machines make to Abec 3 or better even if they are marketed as abec 1. They will have an Abec 3 price and a Abec 1 price to give you a choise, but it will be the same Abec 3 bearing. ANY BEARINGS FROM CHINA WILL NOT BE BETTER THAN ABEC 1. China will put "ABEC 7" or "FUCK YOU" on the bearing if you order 5000 or more!! No laws in China against that. You cant mis-mark the bearings in the other bearing manufacturing Countries. Bearings with a Metal Ball Cage have a 40,000 RPM Rating. Plastic Cage = 100,000-150,000 RPM.

WHAT IS IMPORTANT. 1) The Manufacturer. All Chinese bearings are crap. All those weird name brands are shit. Top of the Line bearing manufactuers make 608's with the proper Raceway Curvature, cages and internal clearances. WIB, GMN, GRW and NMB manufacture the best bearings in the world for skateboard. For those of you not fimiliar with these names, WIB makes all the bearings for "Bones" All Bones bearings marked "Swiss" are manufacturered by WIB Miniature Bearing in Switzerland for Bones. GMN and GRW make all the German Bearings no matter what name may be marketet on the shield. Plastic or non-metalic ball cage will make more way more difference in speed than any ABEC change.
OPTIMAL BEARING: I have used everything in the world, Ceramics manufactured just for my SkateBoard, Abec 9, Bearings Manufacturered by every bearing company in the world. I have access to over 400 Lubricants in my field.
WHAT DO I SKATE ON ???
The best bearing by design right now is the Super Swiss 6 by Bones with SpeedCream. The Bearing had several advantages. 1) It is manufactured by WIB Bearing. 2) They are made with a tight Raceway curvature to avoid "Excess Axial Play" 3) They are supplied with a Re-enforced plastic cage rated at 150,000 RPM 4)Laberinth Non-Contacting Rubber Seals to keep out dirt. This is the obtimum design for free rotation and keeping out contamination.
Ceramic Ball Bearings are only good if they come with Plastic or Phenolic Ball Cages. As a Hardcore skater skating 4-5 days a week. Super Swiss 6 with Speed cream cant be beat. Fuc* the Abec rating. The Abec rating is designed so that the bearing has manufacturing consistancy in order to manufacture mating parts to simular tolerances. (Re: Precision Shafting and Housings.)
Ron

Oh Yeah
... one more note on why the Super swiss 6 has lower starting and running torque (This is Known as Speed to us skateboarders)
All 608's are made with 7 ball compliment. The Super Swiss 6 is the ONLY 608 manufactured with a 6 ball compliment. The Balls all bigger, can take higher load (Impact), Have less ball surphase touching the raceway with 6 balls instead of 7 which lowers the running torque of the bearing making the bearing get to full speed quicker. I am sure within the next year you will start seeing more 6 ball designs, but right now its WIB(Bones) that makes 'em...At all possible, stick with German or Swiss with Plastic or non-metalic ball cages. Any bearing with a steel cage will be slower no matter where it's made. Grease is just an oil with a thickener, the thickener in the grease will slow down your bearing and running just oil will attract contaminates from far away and not provide proper protection. Use the Good-old Speed Cream in the skate shops. By buying German or Swiss what is important is you will know the bearing is manufactuered by a very high quality bearing manufacturer who does the final raceway polishing what the chinese dont, and who it is. There are so many names and marketing stratagies going on with Chinese Bearings, you will get lost in it all. At my old Company we brought in Chinese Bearings for .12 Each. We had the Stamping machines to Mark the Shields. We did PIG,GIRL,SPEED DEMONS, and several others. All were from the same manufacturing lot with different color/marked shields. Any of those weird brands are probably a .12-.18 cent bearing made by the millions with no quality control and several key manufacturing processes left out in order to sell the U.S. for .12 cents.
Bearings marked "Thailand" = NMB
Bearings marked "German" = GMN or GRW
Bearings marked "Swiss" = WIB Bearing
Someone mentioned to me SKF Bearings. SKF Bearings are manufactured in almost every country in the world. SKF no longer manufacturers miniature bearings and hasen't for over 10 years, SKF Contracts out their miniature bearings to the Miniature Bearing Manufactuers. Last year it was IKS and NTN. Could be someone different next year. SKF Specialises in Large Bearings. Don't use SKF....

[Marevix]

There we go. Dazed, you should make a new thread with that post, it'd be a good sticky.

[Jyro Blade]

wow

good info dazed

hard to argue with that, althought i still feel that bones reds arnt ABEC 1...i havta agree with alot of that stuff givin the facts he says there

[redgangsta19]

He said that bones were made in switserland i thought. haha yeah, my walmart boreds say that they are abec 7s. They might aswell say FUCK YOU

[Jyro Blade]

lol nice

and i think it says the Swiss are made there

hence the name...Swiss...
