Hydrodynamic Bearings

Correction: Hard drive spindles typically use ball bearings. It is the read-write heads which ride on a cushion of air (ie they are aerodynamic bearings). Also, the spin stands used to inspect hard drive discs use air bearings.

In this video, Adam introduces hydrodynamic bearings. He covers:
+ The pros and cons of hydrodynamic bearings
+ The construction of a hydrodynamic bearing
+ A step-by-step explanation of the operation of a hydrodynamic bearing
+ A break-down of fluid viscosity
+ Some variations on the hydrodynamic bearing: hydrostatic lift, tilting pad journal and thrust bearings, gases as lubricants

I cannot believe this isn't a more popular channel. Very well done! Thanks :)

[@shobhanpradhan4224]

no body likes to study,only entertainment

[@bigdog1476]

Matt Phillips he does have lots of facts

[@wtarry]

agree - this is great and cant believe it isn't more popular . . .

[@lucianene7741]

That's because this channel is for geeks'n'nerds.

[@rizwanshaikh5472]

Entertainment is for everyone, but knowledge only for the Curious. . .

[@adriansaidan1736]

i am a student engineer that works at a bearing manufacturing facility. This is an excellent presentation of the information and you did a great job at breaking everything down in an accurate and concise manner.

[@zainahmed1994]

best mechanical engineering videos on youtube

[@isabelearaujo8816]

Great great great!!!

[@PacoOtis]

Dude! We definitely owe you a beer! I'm a retired instructor and feel quite good about seeing someone like you who does such an excellent job. You are well spoken and know your material and have very pertinent and well done graphics. Keep it up!

[@greatnortherntroll6841]

Clean, Clear, Concise! These videos provide a thoroughly understandable primer on a variety of subjects, and they're presented in a relatively fun format without talking down to the idiots, or being too dumbed-down for those of us with some knowledge in whichever field is being covered. Altogether, I give this series of videos an A+, or 5 outta 5★ Thank you for making these vids!

[@thiosemicarbizidebenzoylal2921]

Learned this in machine shop junior high school 1978 but its still a good refresher.American education is pretty good if you listen to what the teacher says.

[@mumtazahmed8099]

Excellent presentation for lubrication engineers and maintenance staff.

[@viesturssilins858]

I can't believe that I haven't stumbled upon this channel until now! This is wonderful, thank you!

[@telmorafeiro299]

A couple of mechanical engineering classes learning about this hydrodynamic bearings and its physics, and ending not picturing this. Just saw this video and everything becomes clear in my mind now. Thank you very much! Nice speach, tone, animations, explanations! Very nice work!

[@pstrap1311]

Great video. I'm a fabricator/mechanic in the marine industry and have years of experience installing and servicing bearings of this type in boats drive trains. I really appreciated learning some of the theory behind something I am so familiar with the practical applications of. Thanks!

[@freedtmg16]

Oh man. I found your videos on air bearings and here I am like 4 hours later. You do an AMAZING JOB breaking stuff down. 👏

[@marvinduarte2576]

My friend, i work in a power plant, this video has help me a lot to understand what it's happening when i'm checking clearence in the fans , blowers and also in the turbine journal bearing, you are the best my friend. I really hope to see new videos, thanks from Honduras.

[@elijaholubiyo9408]

This is the best hydrodynamic bearing video tutorial I've ever watched on youtube. Thanks for a good job

[@bryanst.martin7134]

I like your real life example of a typical motorist surprised by puddles after the rain. So feel safer knowing that one or two out of ten motorists are actually competent enough to drive. After wrenching 50 years on everything with a motor wheels, wings or a hull, I didn't learn much from this, but it was clear and precise. Kudos to you good sir. Here's a tidbit you may not know from motor bearings: Motors with nonconductive bearings last much longer and restore full current to the windings instead of shunting through the journal to ground. RC Hobbyists discovered this after installing ceramic hybrid bearings in their hot 3 phase motors, yielding 12 - 15% increase in run time on batteries, and much longer life on the bearings. Keep up the great work!

[@samkachar]

Man when I saw the HDD I got so excited and then the video ended. Why isn't this an hour! Awesome content 🤠👍

[@omarmafia234]

You are just super! It's really rare to find such good quality explanation for mechanical concepts. THANK YOU!!

[@konobikundude]

Thank you for the closed captions! The production value is amazing and accessible. Definitely sharing the channel with friends.

[@JazzLowrider]

Adam you're the best teacher on KZbin, thank you for a clear informative explanation, a good teacher makes a huge deference.

[@indrajith84]

Thanks for the video. You have explained the concepts so clearly with proper pictures and animation. 👍

[@AffandiAiman]

Because of you, I finally understood what my lecturer is trying to differentiate between Hydrostatic and Hydrodynamic bearings. Thank you and may god bless you with all the happiness in the world :')

[@RumpLeINtiLINsKinnIN]

Can't beleive this channel has so few subs. One of the best at explaining things ive seen all over youtube. Keep it up

[@pragyanvashishth5861]

The best video on the topic on the whole internet, thank you for the effort 👏

[@4everVIETNAMESE]

THANK YOU. All other videos just show how they use journal bearings but not WHY they use it. I thought roller bearing was supreme in all ways until I found you. You explain very well and have great visuals.

[@reggraham9180]

Your videos are so refreshing compared to the average youtube crap!

[@aeryxis956]

Bunch of practical information just for free. Really appreciate it.

[@mrraimundo130]

The quality of this video is outstanding. Thank you sir!

[@tungtran9072]

Thank you for making the videos. You said Hydrodynamic bearings are less efficient compared to anti-friction bearings. But My Prof. said these plain bearings have much higher efficiency than roller contact bearings, in which I understood that they allow no metallic contact, hence less friction.

[@OhSryOwned]

So informative! This is incredible helpful. I have been searching for a channel like this for a long time. Please make more videos! Thank you!

[@G_uaz]

Great videos mate, thanks for sharing your knowledge. These types of videos really should be appreciated more. Thanks!
