- You've got questions about this revolutionary new bearing technology? The AvE Bearing research facility has replicated recent developments in the reduction of sliding friction. Surprising technical details are revealed!
This is an addendum to the work of our esteemed colleagues at Popular Mechanics Magazine:
www.popularmechanics.com/techn... - Наука та технологія
Reminds me of an important lesson, very early on at my first factory type job. Engineer I was working for told me to go through this huge box of sealed bearings, spin them like so and put the ones that spin freely in one bin and the ones that don't spin freely in the other. A couple hours later I take him both bins, he checks a couple in each bins and tips my "good" bearings into the scrap bin. Thus began a teachable moment on the role and importance of grease in bearings.
"If you see something too good to be true, ask your self WHY?"
no greater truth, Thanks Mr.Ave for your wonderful videos
HA HA HA I loved this. I work in the skateboard industry educating skateboarders about bearings. Kids like to determine the quality of their bearings by spinning a wheel. Free spinning a wheel with bearings proves nothing. You have to have loads applied. Great video! LOL
+Rat Vision - Skateboard Tech ^ This guy XD
+Rat Vision - Skateboard Tech It can tell you how much grit there is in the bearing.
+Rat Vision - Skateboard Tech Clean out the lubricant and refill just a drop of oil into the bearing is the way to get fast. There is no need for top bearings, if they only have to carry the stress of one persona. If you dont want to have rust, go ahead and oxidize the shit.
Or the kids that brag about the abec rating. Which has no relevance to skateboarding whatsoever.
Tell me this Rat Vision. I put ceramic bearings into my roller blades, on the belief that they run cooler and last longer. Is this true from your observations/experience? I figure you are a good person to ask, because skateboard bearings and roller blade bearings are very similar.

The ending was clever! I kept looking for how the "frictionless" bearing was different... (Face palm!)
Same
Ave, you are a genius of the first order
no grease
I only use frictionless bearings in my perpetual motion machines due to cost and the fact that they can only be manufactured in micro-gravity.
I have a machine that does perpetual motion while generating energy, so I'm going to be rich enough to afford frictionless bearings and HPHT some day soon.
Pfft, I'll use my time machine to steal both of your perpetual motion devices and invent immortality before RULING THE UNIVERSE!
lol
The whole time I'm watching like it's the exact same without grease waiting for some explanation. Apparently I already knew.
same
I thought the makers marks were clear enough.
I await with interest +AVE's 'vijeo' on the perpetual motion machine.
Yeah for the first half of the video I was like it sure seems like hes fucking with me. But then I'm like AvE has never lead me astray. Then he showed the thermal camera and I was like I'm really pretty sure he's fucking with me. So many mixed emotions.
The excessive amount of grease coming out of the left bearing makes it even more obvious whereas the right bearing is completely degreased.
If a picture is worth 1,000 words:
This video is 3:48 sec long, so that's 228 seconds. This video is presented at 30 frames per second, so (assuming a full second of footage for the full duration of the video) that's approximately 6,840 frames (pictures) total. If each one is worth 1000 words, then this video is worth approximately 6,840,000 words.
Matthew Dieck you didn't do the math for the audio
is audio a picture though

Yep. And it's not proper pseudo-German until you add a Scheiße!
It got obvious that something was wrong when AvE mentioned Kantons in Germany. (Switzerland has Kantons and the name sounds like it's in the Netherlands.)
woot? It sounded perfect to me!
Absolutely not, i am german and i can tell you it sounded an aweful lot like dutch. And as Marcus already mentioned, Kantons are only in Switzerland. :)
I speak Dutch fluently. It sounded nothing like Dutch. It sounded like real bad german lol

Theft deterrent.
Well put man! I ride 1 inch stainless steel bearings in most of my long / skate boards, and ceramic in a couple others. The steel heats up and hisses when dry, but I'm a regular sewing machine oil user..so usually no issues...The ceramic bearings don't need any lube at all, and they cruise..although not any faster than clean precisely oiled steel. even if we used pressurized air instead of balls or rollers or even oil / grease, it would still create friction.
I caught this very quick. Had me checking to make sure this wasn't uploaded on an April 1st.
God dammit... if I saw this was from AvE I would have immediately recognized the million jokes and bullshit.
Got me... got me good.
i noticed the reason it was running so smooth before you explained it, i am proud of myself :)
i also did but im not proud but sorry for wasting my time
We got Flexo Print press and printing on film if we no change grease in bearing to oil friction in bearings makes so great that film passing over that roller cant spin it.
Could you tell me how to calculate load on bearings to find the most less friction bearings to put in i got some N force basicly its scale from 5 to 50 where 20 is about if i pull it gently by hand and 40 is like if i try lift up 30kg of ground by pulling
Just cant get our manager to stop replacing bearings for stiff ones and call it a fix.
Will bearings whit no lubricant like ceramic ones make any sense in our application, or just bang grease out put some motor oil in normal metal ones and make it a day.
I seen air grafite bearings but they look like overkill. Which cheap bearings would be best for high speed low load ?
I was looking up rolamite diy examples, and came across this gem. I have been watching AVE for at least 3 years, that I can think of. This goes back 5. What a change. I didn't hear one "Focus you Puck!" and "stick on the ice" has since evolved!
Electric motors are designed to run many lifetimes, but they fail because of human touch. Premature failure due to...... You can always track it down to somebody.
Bill Lewis short lifetime.
Abom79 correction they used to be
now manufacturers purposely undersize the windings on motors so they heat up quicker thus failing quicker they also weaken other parts
electric motors are super simple it takes engineering to make them fail faster
Bill Lewis it is a lifetime oil
its not your lifetime its the manufacturers specified lifetime which is a few years
Abom79 "Electric motors are designed to run many lifetimes"
...If they are stoutly engineered and built for their environment, as well as under the proper loads.
Abom79 That USED to be the case, now we live too long to outlast anything...... Motors included....
I've worked in the aviation industry too long....at the beginning I was like....."well yeh there is no grease on that one". Time for a new career.
Your German language skills are unrivaled. Thank you for your contributions to linguistics and engineering.
LOL ROTF! Loved it! thanks!! Good to have a little humor and yet, I'm guessing that there are few who NEED to be shown. Well done!
When you see the word "frictionless" you know it's gonna be total bullshit, unless someone is talking about a sea of Superfluid Helium. But that stuff climbs up the side of your boat, fills it, and sinks it before you can put anything in it. :P
Any skater will tell you you can rip the inner guard off your bearings clean out the gunk inside, and make your wheels run a lot faster - but at the expense of wrecking bearings fairly quickly.
What a helluva way to die.
Sweet! I'm gonna bring this up to my boss, tell him that we can save money on grease and fuel by going with these new frictionless bearings. Hell even save me some time and getting covered in grease. Shower once a week here i come!
Watched the popular mechanics video, they said about putting little divots in the groove to make the bearings stay apart. Sounds like a very bad idea if under heavy load. I could see this causing all sorts of bad wear and tear. If i wanted speed bumps in my bearings i could just add sand and be done with it.
Always fun to rewatch - made me catch interest for your channel. Retourning customer ever since!
I've been waiting for six years since this was posted for technology to finally catch up with the frictionless bearing in my head using neodymium magnets and ferrofluid.
No wonder Leondardo Di Vinci always looks stooped over -- all those people standing on his hsoulders... ;)
OMG. Why arent we funding this? I am in need of some high rpm, very strong frictionless bearings (for racing porpoises). I NEED THIS!!!
be gentle with those porpoises
+priit mölder I cant wait to see racing porpoises, you should put them on youtube, thats a viral video for sure !!!
Why a porpoise would need bearings is beyond me, but ill wait for the video to check it out for myself
LOL
Y aren't we funding this?
If you engined up with two porpoises then you'd have a genuine multiporpoise vehicle eh?
A man without a porpoise,has no porpoise at all! :P
This reminds me of the old shop videos from school. Love it.
what is the difference in terms of accuracy between setscrew pillow block bearings and press fit bearings? If you are building a table saw .. is it better to use a press fit bearings on a hub/mandrel or two set scews pillow blocks?
a bearing that isnt under load.... yep a fidget spinner
LOL....I watched till the end thinking, Yeah the bearing without grease will spin and you heated the other up with a blow dryer to do the FLIR thermal test. great spoof 😆
i believe the IR reading difference is due to high emissivity of the grease.
another awesome vid,Ave you are doing a great service for humanity improving the quality of life for all shed dwellers worldwide
Nice design! Can your frictionless bearing work under water, specifically seawater?
how much for them high tech bearings
I thought you were going to talk about magnetic bearings... not sure if they are frictionless but they are quite enough to not need hearing protection. Huge noise difference in a chiller plant that uses standard bearings vs the magnetic.
Induction does basically the same job as friction in this case, That along with the air, still a massive improvement regardless
I just spent multiple days and a decent bit of liquor watching every video on your channel. Good stuff man. Learned quite a bit (Stuff I will probably never use but is good to know) and it kept me entertained. Lots a humor hidden in the videos. Keep up the good work!
This is a really insightful video. Thanks AvE!
I was getting ready to call bs glad I waited to the end to comment.
"Keep your stick on the ice."
Ohhhh, so that's where the vice reference comes from.
Excellent - more of this please
I use to repair large servo motors. Much amusement was had by cleaning out the grease of a bearing, getting an air line and while holding the center, spin the thing up to crazy rpm and then dropping on the floor.
I got full ceramic bearings for my friends motorcycle and they say "use no grease or lube" on them, just blow them out with wd40 from time to time to remove contaminants and they are good to go. Could they be classed as "almost" frictionless? I never spun them before they were installed so don't know how long they spin for :)
toysareforboys sealed bearings require no maintenance
***** So what, that makes them better? lol!
+toysareforboys In most cases people do zero maintenance on bearings so YES a sealed bearing can be better in that case. The human element in maintenance is usually the weakest link.
+Swedish Assassin Yeah when those sealed bearings seize up you just throw them out and buy new ones.
Your tests fall short by failing to account for the automatic inversion which causes a periodic fluxtual digression in the bearing race. This throws the Δ into a lepton flux which resulted in a busted ring smelling like soapy cat pee. Please, sir, take these transignation quanitifiers into account in the future!
Yeah! What he said!
Any chance you ever have or ever will test this NMF friction reducer, snake oil stuff?
sounded like it was rattleing at the end.. need a fair comoarison..
i need a berring woth untra extreemly constant friction.. what should i use?
I love this video. This was the first video of yours I ever watched. I was so ready to start calling this out as a scam before you came out and made it a joke. Love this channel.
just watched the pm link... lol. just pull your bearing apart, grind some very crappy grinding spots on your inner and outer race, throw the cage away and move on. amazing, somehow the cage is the main source of friction and not the load placed on the inner/outer race pressing on the bearings!
lol, how did even PM let this article out?
I know old video and all, but was wondering about your opinion on ceramic bearings?, I see these have become very popular around the race track and race bikes.
@ave I know, old video, but how would full ceramic bearings fit in this comparison?
NO LOAD + NO LUBRICATION = NO TEST
I use to watch kids adjust skateboard wheel bearings based on the spin test and I was like NO! You don't understand!
can we just make a bearing out of magnets already n move into 2019.
@AvE, How is that possible to have 20°C ambient temperature in the shop? Have you moved to Guadalajara?
I´ve been selling bearings my whole life. The only way to achieve more resistance related with speed and temperature is by buying bearings with special nomenclatures after the bearing number such as c3 c4 c5 c6 (608-2rs- C4) that means the groove is bigger for ball expansion due to high temperature. The bearing that you showed in the video is a 31304 a metric tapered roller bearing from Timken, and there is no way to obtain a high temeperature o speed conversion of it, neither on the inch series, it will be all on the grease. Deep groove ball bearings on the other hand have multiple options, as I said before an expanded groove or maybe an special housing with special lubricants. There are also ceramic bearings that are quite superior that steel ones.
You are forgetting the main benefits for Brinelling. After the pesky smooth furface is gone in about 30sec, these bearing testicles will have a much greater laminar boundary layer.
If you add a couple magnets to the sides of these revolutionary BearRings that almost propel them selves you pretty much have free energy!!!
What about the extra brake wear and speeding tickets, there is no such thing as free energy. You need to add a capacitor in serious parallel to obtain any benefits.
A bearing under no load is called a spinning fidget. Those stupid annoying spinning toys that seem to be all the rage.
Ok Boomer.

You use that as if it's an insult.
It's not an insult to me so ...try again!

@@valveman12 Somebody really likes fidget spinners hahahaha
where did you get your thermal sensor from?
Great demonstration!
Great video! As a kid I'd always put the fastest spinning bearings on my skateboard... However it didn't work nearly as well as the bearings that didn't want to spin easily! Since then, I knew! Ps. Do a video on ABEC ratings and their myths.
+Ian Thompson He says in another vidjeyo that the trick to a fast skateboard is to run unsheilded bearings dry/with light oil. if you want to go fast and don't care if it lasts a week or a year that is..
ha ha. I instantly realised the only difference was grease.
Hi, thanks for the video, you made a very good point!
Have you ever head of full ceramic ball bearings? A friend showed me one the other day and I was baffled! I can't even figure out how they put those together.
agnostos1000 They insert the balls between the two loose races, and then when all the balls have been installed, they separate the balls with the cage.
Without the cage, the balls can cluster together on one side of the race allowing the race to lift away from them in the other direction.
They use cages made of slightly flexible nylon or teflon so that they can be squeezed between the balls into place.
I was wondering why you had the semi bearing I used to build my rotary bedroom closet organizer for my hiking/hunting/camping shit. It's kind of a two season deal. One side for cold another for warm weather gear. Thus I never have to go digging when the seasons change I simply revolve the whole unit to get the weather appropriate gear.
bearings are not frictionless otherwise they would spin forever
What about drag?
the closest thing to frictionless is using 2 repelling magnets in a vertical direction but even that has limitations
+Nick Silcox There are frictionless air bearings that are ground so smooth that they float on a cushion of oil between the 2 surfaces. They are completely frictionless.
+Chris Shaw I would not say completely frictionless. Because those surfaces are in oil, that creates drag and friction. Not a lot but it's there. And Those bearing exists, their called "plain bearings". Railroad wheels, crankshafts, and cam shafts use plain bearings with a thin layer of oil to keep the 2 surfaces separated. Unless there is no air and its levitating, there is no complete frictionless bearings.
+Chris Shaw my vb36 wood turning lathe has those, but they are not frictionless, some turbines use compressed air as the "lubricant" but even air can create friction though it would be very very very very low
+Nick Silcox limitations of repelling magnets are load capacity before the repulsive force is overcome and the surfaces touch. Also side loads if on a wheel.
There might be a small amount of friction due to eddy currents but this is negligible.
+Tim Lewis its possible but eddy currents primarily effect stator in the iron core when the iron core becomes magnetized and decreases the efficiency and power
inless it is in a complete vacuum, there will always be friction from air.
Half into video I thought this is another "magic" bearing video...
Great stuff you explained there!
I came here looking for actual shafts that use trapped air we bearings to spin the housing on. I believe the technology was patented by FUJI in Japan. I believe it was Fuji that patented many enclosed sand blasting techniques. One of the which was essentially trapped air as bearings, or whatever it might be called. Still searching this decades old technology
Back in my skateboard hooligan days i had a buddy that would always gut his bearings and run them dry, and he could roll for miles. Shoulda capitalized on the idea back then damn it
Yeah, he would kinda spray whatever was kicking around in there randomly to get the dirt out haha. I used to use a teflon based lube mixed with the grease, lol. Young and clueless. I never had any issues with them though
Back in the 80's I used to tear apart my bearings and throw the balls in a small (roughly 6oz can size) tumbler with shredded newspaper I put through the blender. Turn it on and leave it for a day or two to polish while tried my best to polish the races with newspaper as well. Then I reassembled them and used graphite. Worked wonderfully well... too well at times, as after a wipeout I'd have to chase after my board for a 1/4 mile lol. The biggest flaw was that polishing the bearings made them rust rather quickly if it was humid or simply left unused for a few days. (whatever coating they came with now removed.)
DJ Dragon Using graphite on steel parts is a bad idea as it absorbs moisture.
Bob Cartwright yep, graphite absorbs moisture, but it's still widely used on steel, from bearings, high speed machine tooling, hot and cold forming, bolt threads, and engine blocks as compressed graphite iron, just to name a few. Anyways, I was simply talking about trying to get some better performance out of .50 cent bearings in a skateboard as a teen in the 80's. Who cares if they rusted? (mainly due to my polishing the metal rather than using graphite)
You can test bearings under 0 load with a lunar wane shaft.
s0nnyburnett But you have to make sure that the bearing is surmounted in a logarithmic casing to prevent side fumbling.
sivalley
Only if you are testing spurving bearings.

I thought that's what these where!

This thread is amusing because i understand nothing
so I found this very interesting... I was recently in Vermont and your videos were very easy to find. I could have sworn I had subscribed to your Channel..... I have watched many of your videos long story short I moved to Denver your videos were no longer popping up I didn't realize that UA-cam is a regional thing far as what pops up under recommendations to watch. thought you would find that interesting.
keeping us on our toes....nice
Try smearing it with concentrated chooch and see how long it spins. Over unity is all dicked up but chooch paste is skookum. You can quote me on that.
Fiction bearings!
Watchin these vids definitely keepin me better at my daily hackery of things...good stuff!
very useful demonstration!
HA! HAHAHAHAHA. I was watching it the whole way through saying to myself, What the Frickins? It looks like the same exact thing only one is dry. I even called the wife in to show her why DRY IS BETTER.......
Thanks to your masterful video.
I no longer have to prelube............
If your wife isn't pre-lubing automatically you're not pressing he right buttons ;)
Dry makes blisters on the business end of the dingus.
Aerospace grade marketing BS! High quality flim flam.
Glyph To be fair, they probably do decrease SLIDING FRICTION by an order of magnitude with no retainer cage to slide against. There is still the main foe of ROLLING RESISTANCE, that depends on high pressures delivered through detailed nano models of the surfaces that incorporate the feedback effects of heat transfer.
I don't have the working knowledge to judge if this is a valuable or significant improvement. I am also curious as to how the ball separation varies during changing acceleration or loads, and how that might affect performance/longevity.
actually, friction causes heat, but this is a good use of click-bait. You shrewdly got people to learn something. Great job!
Never have I ever heard such a wonderful name fur ein Deutsch Universitat and been so grateful for my meager two year education in German.
have you heard of a company called skf my dad works there they make bearings
Steven Davies I usually try to source SKF bearings when possible, never had problems with those.
hahahah yeh
did y know S.K.F invented the first roller bearing in 1907
Steven Davies Er no, it was John Harrison the English clockmaker of longitude fame who made the first roller bearing in his Clock H3, started in 1740 and finished some 19 years later. www.frodsham.com/harrison-h3/
im sorry the bearing type i meant was a multi-row self-aligning radial ball bearing. but coud'nt remember the words
When pray tell will there be force field bearings, I'm very disgusted with the odor of chooch lube. Sooooo deprimido
***** they already exist they use electromagnets and are used in operations that a normal bearing would contaminate like handling gasses and oils to uranium enrichment
imchris5000 yes, but they are not able to take much load, the loads I'm thinking of.
***** yes they are
electromagnets are incredibly strong
they are used with huge loads
electromagnets can move hundreds of tons
imchris5000 linear, yes they sure can. I agree.
***** Google is your friend SKF markets mag bearings for all speeds and loads, especially high speed/load generators with 100+ton turbines
Thanks for the education
Is it still the 1 of April?
Actually SKF are selling low-friction bearings but what they have done I think is just to lower the amount of contact surface. That means the contact pressure increase so they must have a slightly better material.
Since low losses is popular nowadays they have decided to sell the bearings as "low friction" instead of "higher capacity".
Technische Universität "Ich muss scheisse machen" XD
+Oerg866 LMAO
this guy is too troll
Hi mr AvE. Are these friction less bearings classified with the same size measuring system if that's the right term as standard bearings? Also, would you happen to know if they take as much load as the standard type? A set of these in my swing axle vw would be dope! Awesome vids as usuall, take care!
No. See the problem here is he's conducting a non-uniform test. He's obviously spinning leftie bearings to the right and rightie bearings to the left. Hence why the spinnaker factor seems diminished in the rotational forces in the non-laden position. So to answer your question these are dwemer size and therefore not acknowledged by the code of standards decreed by Severyn Aerelius the 3rd. Your best bet would be to use a company such as SKF bearings to fit your "sitzen dupen platzen" VW. Regards
The IR thermometer reading is a nice one... almost tripped for it, forgot about the emissivity of the grease is higher than the metal surface.
Actually, absolutely nothing was explained. Useless video!
+AvE some peeps just don't get it
+The Guitar Whisperer I think his point is that you can't get frictionless bearings.
The Guitar Whisperer 2:45 numb nuts
Can I use these in my turbo encabulator?
This video was visionary. Two years after publishing this, everyone would be flushing the grease out of their fidget spinner bearings to make them spin longer. And now we probably have a whole generation believing that bearings work better without lubrication.
do these come in skate besring size?
Good thing I watched till the end, being a fella that works with roller bearings, tapered roller bearings, ball bearings, plain bearings, etc, etc, etc on Helicopters - I was going to slam this video - till the end, where I breathed softly and said "Thank you"
Thank You
Any chance for covering magnetic bearings please?
Haha I figured out this was a prank when the one on the left was 36 degrees. Thats pretty warm for a "brief" spin. Good video. I like the message behind it!!!
