Frictionless Bearings - Technical Secrets Explained!

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:

[@Mylitla]

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.

[@RatVision]

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

[@kernaussage85]

+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.

[@shoeyfiend7781]

Or the kids that brag about the abec rating. Which has no relevance to skateboarding whatsoever.

[@MrBilld75]

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.

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.

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.

[@wompstopm123]

[@redgreenblue998]

[@jaredj631]

I was getting ready to call bs glad I waited to the end to comment.

[@thefastinglionproject3270]

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.

[@joetaylor010]

God dammit... if I saw this was from AvE I would have immediately recognized the million jokes and bullshit. Got me... got me good.

[@Elseveno]

[@toysareforboys1]

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 :)

[@s0nnyburnett]

You can test bearings under 0 load with a lunar wane shaft.

[@RuzzP]

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

[@DriftingDragon74]

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.)

[@MrEh5]

DJ Dragon Using graphite on steel parts is a bad idea as it absorbs moisture.

[@DriftingDragon74]

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)

[@Batoo76]

Fine and clever mythbuster introduction. Teaching people on this example is great.

[@gamingSlasher]

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".

[@NickSilcox3]

the closest thing to frictionless is using 2 repelling magnets in a vertical direction but even that has limitations

[@chrisshaw1294]

+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.

[@NickSilcox3]

+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.

[@ravravensdale1963]

+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

[@TimpBizkit]

+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.

[@NickSilcox3]

+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.

[@bchant19]

I think you've just saved me from shelling out a massive fortune in buying all new ceramic wheel bearings for both my motorcycles. I've seen loads of videos of bearings being spun up with compressed air and rpm reading taken showing more rpm's on ceramic which is sold as being less friction so more better but with no load on it of course its gonna be better by a mile but what happens when the load gets applied. Id love to see you rig something up that could demonstrate a "low friction" (i.e a fucked one) bearing vs a normal bearing

[@tonyus8197]

What you demonstrated dear sir, are two identical bearings, just one with grease. What the article talks about is a ball bearing (not tapered roller) without the "cage" to separate them ball's, thus (theoretically) eliminating the friction between the ball and the cage. Nice theory, but as you said, testing a bearing under load is the real deal.

[@MountainStorm]

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.

Funny, when o was in high school 1968, a rep from Ford Motors talked to our class and his first topic began with rotating a large plywood wheel standing vertically. The wheel spun throughout his discussion on new things in industry. When his discussion came to an end he the returned to the wheel and asked if anyone noticed it was still spinning? He the pointed out that the reason was that it used an air bearing. I have heard of them used in aerospace since. I do not know how they work, but the friction element is very low. May be you can enlighten me though not likely as my densification level is fairly high.

Right off the bat , in the title it says"frictionless bearings" I thought "no such thing" Then you spun the bearings and I though " well of coarse it spins fast with no grease". 2 things this brings to mind. Friction in quality bearings verses cheap ones. And a story I heard about bearings with to much grease causing more friction because the grease has to move around the ball or roller to make room for it to pass.

I bought an old second hand 20 Quart Hobart food mixer, and after using it for a few years in a bakery setting, opened it up for some reason or other, only to discover that, either a couple of the gear shaft bearings had never been greased, or, at some stage they had been replaced without grease. Given the pristine condition of the grease covers, I suspect the former. I just applied some grease and used it for about 20 years more before selling it.

Frictionless brgs refers to ball bearings. Taper roller bearings are high load, lower speed. Ball bearings outnumber roller bearings because they have many more applications.

[@w3vjp568]

The secret to building any decent perpetual motion machine is choosing only those bearings from the very lowest end of the bell curve distribution, where the friction coefficient is negative.

[@constantinosschinas4503]

caged ball bearings where invented by the Romans, not leonardo davinci. It is well documented that romans used balls between plates to make it easier for big sculptures to turn around, for show off. Roller Bearings were used by the Egyptians, found also in drawings. A patent of modern caged bearing was in awarded in 1794 to Philip Vaughan.

If you have one with ceramic balls it will spin even longer. My friend has some at his motocross shop on display and both are complete clean of any lube, yet the ceramic one will spin 3 or 4 times longer than the steel one.
