Ceramic Bearings need lubrication?

In this video I talk about ceramic bearings and do they need lubrication, which is kinda what the title says - funny that......

Silicon-Nitride is quite impressive. I think the latest generation of ceramic-based materials has the fracture toughness for duty in an engine, no problem.

[@jacoblatour6192]

Was wondering if these full ceramic ball bearings in could be used as crank bearings in a 250cc two stroke

I work in an office I don't swear all day but deep down I don't trust people who don't swear..what else are they hiding...

[@rcsendandblast1579]

I have few real good friends. The good ones swear and shat and we all know each other closer then anyone who does not cuss 🤓

you developed to my favorite person on youtube in just a few days :D

[@dirtygarageguy]

That's becasue I'm awesome lol

[@69waveydavey]

As I have said before a material that is very slippy is best for bearings, i always use bearings made from banana skins I find they are the best all round.

[@lolatmyage]

Do they need lubrication?

[@69waveydavey]

Yes, but it must be a vegetable/fish based lubricant, I find smoked mackerel oil to be best and the fragrance is out of this world! Banana/mackerel, Mmmmmmmm

[@11jeopardy11]

nice use of the white board

[@pentecost66]

My Ford F-350 6.7 super duty has ceramic ball bearings in the turbo charger. 60 degrees here in Alaska with 20 hours of daylight.

[@dirtygarageguy]

"Alaska with 20 hours of daylight." - and you have internet? lol

[@TsunauticusIV]

I’m surprised to hear you say “gaulding”. That’s something you typically hear in the southern US. People where I live have the ole “gaulded” isn’t a word debate. They say it’s “galling” and not “gaulding”. I don’t get in the debate. I’ve always said “galling” or “galled”. So I personally don’t mind which word a person uses. I still understand the meaning either way. Lol. Just never heard a foreigner use it before. Cheers bud

[@cheezemanrich]

What about ceramic pistons and cylinders? What's your knowledge of that? I have always wondered why nobody does it. Love your videos, has increased my tone on KZbin significantly.

[@dirtygarageguy]

Great question, video added to the list - matt

[@rsmit2797]

Not sure about tough? Don`t tough materials have a high modulus of elasticity, and a high Young`s modulus, (most types of steel)? Ceramic bearings are definitely strong, and so have a high Young`s modulus, but their elasticity is low, therefore they are relatively brittle. You can smash a diamond with a hammer blow. I suppose you might mark a steel ball? Love your vids - How do you make so many? X

[@dirtygarageguy]

Strong is term we don't really use in engineering with a more descriptive add-on so to speak. Tensile strength, yeild strength etc are more apt. You are right though toughness or being tough was the wrong word. Shit the bed lol

[@rsmit2797]

You`re right. Strong is too imprecise. Brilliant the way you reply to my pedantic comments! Thank you. X

[@dirtygarageguy]

LOL no worries mate

[@arielerosa3204]

What happens if you lube them with graphite

[@quentinludwigs]

Very interesting.

[@HOTSHOT-ls1bc]

Tokyo mods sell ceramic bearing for most 450 dirtbikes bit can they take the beating

[@chris7605]

You don't know what you'r talking about ... First understand what is lubrication, then you'l realize that ceramic bearing due to their low friction coef., don't need lube. It makes the opposite effect.

[@dirtygarageguy]

LMAO! Dumb comment of the week - well done. You said it yourself knobhead; "due to their low friction coef" i.e there is friction - friction = waste heat and wear.

[@dylan9768]

i was told ceramic bearing can shatter under very high load (like if the motor locks up up or drops a valve or something) where a steel bearing wouldn't, is this true?

[@dirtygarageguy]

Depending on the bearing material, but generally they can do. But that's selecting the wrong bearing for the application

[@DanielMRamos]

There are bearings that require no lubricants in the traditional sense. There are three I can think of off the top of my head. Air bearings or steam bearings do not require conventional lubricants as they self lubricate via the flow of air or steam. Air bearings are awesome, but require precise manufacturing and a power source to work. Magnetic bearings do not require conventional lubricants either as it is also a contactless bearing technology, but it also requires a power source. Electrodynamic bearings are also contactless bearings which are similar to magnetic bearings; however, they use the lenz effect, so it is a more passive magnetic bearing technology. Any kind of contact bearing will eventually reach a physical limitation, hence conventional lubricants will be required in my assessment. Some bearings can operate using dry carbon lubricants, but they are not suitable for engines.

[@Farlig69]

2:10 Harder AND Tougher...? Sure about that?? I thought as hardness increases, so does brittleness ie toughness reduces...?

[@dirtygarageguy]

Harder and tough vs A1 tool steel

[@mikegrady4]

Used to run them for my kart reae axle. They don't like dirt....at all. I went back to the original bearings......because in that application, they are shit. PLUS, they cost 4 times more money....

[@julianwilson5174]

Didn't mention fidget spinners once.....

[@stephengardin2423]

How can you possibly say it's too hot. You live in England. I live in Nova Scotia, Canada. Our summers amount to about 5 weeks; very similar to your summers. Are you daft? I'd seen plenty of your countrymen in Italy on holiday. We called them lobsters. Couldn't get enough heat. Man up and grow a pair. Thanks for the info..

[@dirtygarageguy]

Look, I love the cold. And in England we have sweety heat, not like Panama - I will never go back to the jungle ever again!

[@stephengardin2423]

The jungle sucks the big one. Our sweaty time is in mid to late August. It's like a Louisiana Bayou. All the heat and humidity comes up from Florida. It's unbearable. I have accepted all the seasons. If not you suffer too much.

[@youresushi]

If you go the real Direct Injection closed-exhaust-port route with high pressure fuel pump, what if you use the high pressure fuel for a hydrostatic bearing?

[@dirtygarageguy]

lol so even though its extemely hard to get away with doing Direct injection, you then wanna increase the demand on that same system? Are you actually mad?

[@youresushi]

Its not engineering if its easy :)

[@Wtfinc]

What happens when a ceramic bb shatters at high RPM? sub micron tolerances? I bet.

[@KurumaDesigns]

"And they're big nipples" lmaooo

[@bepositive9259]

Does ceramic bearings for inline speed skating (608) required lubrication? If yes then which type of lubrication..i mean cream based or oil based?

[@dirtygarageguy]

a light grease would be good

[@bepositive9259]

Thank you!

​@@bepositive9259thank you for your question this is my questions so I am clarify

[@Fazaian726]

Does ceramic bearings on the bottom bracket of my road racing bike needs lubrication? I am putting 300watts and 85 pedals per minute on average also I have noticed that when i first intalled them they were silent bot now they make that noise like they are dry and they are still smooth. Help me out I'm confused

[@mitchellcollins9094]

Can I put this full ceramic bearings on my fan motor

[@lomasshaun8709]

some funny people about

[@mandernachluca3774]

Nice one :D

[@vincentyap3188]

do full Ceramic bearings need to be lubraton on a motorcycle?i am using Zirconia ceramic bearings which is harder than Silicon nitride ceramic bearing

[@dirtygarageguy]

All bearing have friction, all bearings need lube

[@vincentyap3188]

@@dirtygarageguy Ceramic bearings have very low friction duel to it do not absort heat, which heat created friction and Zirconia ceramic bearings is the best at heat resistant as i have do a research on this, dude

[@dirtygarageguy]

Was that a question or an answer?

[@vincentyap3188]

@@dirtygarageguy However, friction or no friction as long my ceramic bearings always more spin than steel bearing and my bike perform better than steel bearing and my ceramic bearings can last in high temperature as steel bearing cannot last, and my ceramic bearings can be use without any lube, and it perform great, better use it for yourseft instead of just making wild guess in your video, other have use it on their bike and they are happy about it check other video at kzbin.info/www/bejne/Z6WXo2qPrcR_eK8 not like you not even test on a bike
