i was wondering what are the best all around bearings. I want some that can r good for everything (sliding, dancing, garage, dh ect..) and im looking for alot of speed but i usually never go more than thirty mph in the garages i go to but i want the fastest ones without serius downhill bearings just the best bearings?
The best bearings are the ones with removable shields/dust covers that you maintain.
Bones Reds, Speedy Lunatics, and Pleasure Tools all meet this criteria as do others.
DO NOT spend gobs of money on bearings! Regular maintenence is a far more important factor.
my bones swiss are nice and smooth. 30$ from daddy's. they have the removable shield Brute379 mentioned. Keeping any bearing mantained is the most important thing. Don't get anything from China. Get some Bones Speed Cream. like 5 bucks.
Oh yeah .....lol and that garage....you meant 30Kph right.??? not Mph. 30Mph in a garage is haullin' azz.

Dude reds are made in china... are you telling the countless amount of people who swear by them that they should not buy them anymore?
Sorry if that came off a bit hostile, but not everything from china is bad news haha. Really as long as you stick with well known and trusted companies regardless of where their manufacturing takes place you should be good.
I highly recommend Bones Reds, and I wish I had a 30mph garage haha
THIS WAS ORIGINALLY POSTED BY TORO
"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 "#### 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 ####. 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....
. . . . . .
Yes, the Bones-Chinese[Reds] are in the same class as the other Chinese Bearings. Bones China are may be a little better than the other China or unmarked brands as far as consitancy since they probably been using the same China trading Company for years, but still is a .12-.14 cent bearing.
. . . . . . .
On your third question the smaller balls tend to brinell the bearing races easier than the larger ball will. A brinelled race will have little indends from the balls impact, basically destroying the bearing. Thicker races will make the bearing a little stronger from the standpoint of cracking the races, but that should be a rarity. But Brinelling the bearing is more common than cracking races..Should be...
As far as Bearing failure, Brinneling is one reason, Lack of proper lubrication is #1 cause for bearing failure because once you run metal on metal and balls and raceways get scored, everything will wear and fail quickly.
As far as Oust Bearings...Its another Marketing Stategy. Look, it comes down to everything I said in these bearing post as far as the bearings configuration. Notice the low end Oust MOC5 is "Carbon Steel Cage" with standard non-contacting rubber seals. Their Rolls royce is the MOC9. Here is their desciption of the Seal "The Moc 9 Buna Non-Contact Seal is set into a U-channel design in the inner and outer races to keep all foreign particles out of the ball area. It also stops any oil leakage that might occur on a standard bearing seal." THIS IS THE LABYRINTH INNER RING and seal weve been discussing that the Bones-Swiss, Black Hole Bearings have. The MOC9 also comes with a non-metalic cage....thats what makes it quicker than the MOC5. No matter what brand you like, 1) get bearings with a non-metalic cage 2) Buy the bearings with the Labyring inner ring and seal design,no matter what they may call it. Your bearings will outlast a dozen sets of the old style shielded bearings.
. . . . . . .
The Swiss and German manufacturers make their 608 with a tighter raceway curvature as well (harder to mfr.) than the Chinese. This eliminates a lot of excess axial play(end play)in the bearing.
. . . . . . .
....As far as installing, VERY good question indeed. You can ruin a bearing installing it before it turns even once on your axel. The Rule is "Only apply preasure to the ring being mounted." To put the bearing in your wheel, some people put the bearing on the axel, unside down and press the wheel on the bearing. BAD ! The pressure against the balls can brinnell the raceway if hit with too much force. Since the Outer Ring is being mounted in the Wheel you need to apply preasure to the outer ring only! Not the inner ring. I use an Old bearing that I disassembled and h
Best bearings?
