Title: Rockin Ron's Bearings Back In Business
Post by: maggotspawn on July 29, 2018, 09:56:48 AM
I got a message on Facebook from Rockin Ron. I had asked if he was still making bearings a while ago.
Apparently he's back in business. No ceramics in stock yet, but he has the Rockets for sale.
I had some about 5 years ago, they're fast.

They are well worth the money. Easily on par with Bones Swiss. Just try to ignore the stink bugging longboarder/ Kurt Cobain impersonator (yes, he's in a Nirvana tribute band) aspect to his lifestyle and treat yourself.

I'll be honest, I'm not dropping $85 on bearings anytime soon. I do like trying new products and giving companies like Ron's my business. With that being said, are these really better than what ever mid-level bearings I'm rolling right now(super reds)?

I prefer the 20 something dollar ones over swiss, so much so that I am willing to try the ceramics.

$22 for bearings that are easily as good as Bones Swiss.

I once got his cheapest bearings (Rockets?). They were faster than Bones Swiss out of the box but seized up (due to my own neglect) as quickly as generic bearings. I realize that there are too many variables to accurately compare bearing longevity, but some are clearly shit (Lucky) and others are clearly better (Swiss).

I get a least a year out of mine. Sometimes clean them sometimes don't.  Ron's a weirdo but he knows what he's doing.

a great example of buying cheap chinese bearings and then selling them as snake oil.

Not striclty true. The shields might be. He is an actual bearing engineer who knows what he's doing.I believe George Powell even took some ideas from him. Anyway, I'm not here to defend the dude this much. I just like Swiss quality bearings for $22. Bones 6Ball when I'm feeling flush.

If everyone is always comparing their bearings to Bones Swiss, then you know they are on top of the mountain. It's not like Bones has ever had to say, our's are just as good as Bronson/Andale/HL if not better.

They are re-packaged NMBs. They've always been one of the better bearing manufacturers and far better than generic Chinese bearings. I've seen some NMBs sold on eBay or sketchy online stores, but I don't think anyone else imports them (and haven't seen them in stores for 20 years). Back in the day, German (GMN) bearings were between NMB and Bones on the hierarchy, but I haven't seen those for a long time either. I think Z (Z-roller) bought exclusive distribution rights to GMN during the late 80s and sold a version soaked in motor oil.

Just the same, you're better off sticking with Bones if you can afford them.

This is probably close to a 20 year old post from
ron, but he gives a breakdown on skate bearings. The big takeaway is that the skateboard industry uses the same few bearing manufacturers and they're mostly crap with cool branding. I think most of us know that by now though

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.
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.)

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 have the outer ring only, put it against the outer ring of the bearing being mounted, and a small block of wood and rubber mallet. As far as removing them, another good reason not to re-use the bearings. The same rule applied to dis-assembly if the bearing is to be salvaged. However, there is no way of removing the bearing using the outer ring. Even the bearing pullers must remove the bearing by pulling on the inner ring. Brinelling will not happen everytime you mis-mount the bearings, but the degree of damage can be so slight, you may not notice. Yes, I use a bearing puller when removing bearings, however, bearing pullers were desighed for alot bigger, more durable bearings. Using a Bearing Puller on a Miniature can and will cause at least microscopic damage almost every time. Remember: Only apply pressure to the ring being mounted. Alot of people ruin their bearings before they even start!!!
