In this video, Adam introduces anti-friction bearings. He covers:
+ The function of a bearing
+ The two main categories of bearing: Hydrodynamic and Anti-friction
+ The construction of an anti-friction bearing
+ The main types of anti-friction bearing: Ball (Deep Groove Radial and Angular Contact) and Roller (Cylindrical, Needle, Tapered, and Spherical)

I have to say; Great production quality!
you making a video on Bearings or something?
Hey Cody!! What's up?
bear my children
Fancy seeing him here....
I liked both comments
Surprised this channel isn't more popular. Very well put together.
it's not more popular because the guy is fuckin weird
I'm watching these videos that are like "journal bearings suck, roller bearings all day" and this guy's just over here like "ALL BEARINGS ARE GREAT, SO MANY COOL FUNCTIONS". Love the enthusiasm. I've been reading shingley for 10 hours and these videos made it all click in 10 mins. thanks!
Hey Adam, Great video. Looking forward to seeing more from you. All the best, Tom
Hi, Tom, Thanks for the comment and it was great chatting with you the other day. (Btw, love the mousepad)
"It depends on how much " load" is on your shaft." Ahh...apparently not a whole lot on mine these days...🙄😂
Thank you for this great overview of anti-friction bearings, sir!
You are nothing short of an amazing teacher. These videos are so information dense its mind blowing every time I see a new one.
2:15 I got all kinds of loads acting on my shaft
stenobro recip
I hate this
5:36 Maybe you need an angular contact ball bearing to support a large amount of thrust load ;)
This is the first time I have ever heard or read them called "anti-friction" and not "ball" or "roller" bearings. Ain't all bearings supposed to be "anti-friction"? I get that it's rolling resistance vs sliding but they both are designed to minimize friction.
skoronesa It is a bit confusing but common in industry to differentiate anti friction (ball or roller bearing) and plain bearing (pin and bushing).
Studying for my redseal and your videos are really helpful for review. Thanks! Keep em coming!
What about the ball rolling on two races wich have different circumferences ?
You should make more videos. The way you explain everything I find it very effective an unique way to understand even complicated topics.
Really awesome video with short and great explanation with showing different images. Hope again I will see this type of introduction on any topic.
Please keep on making more videos like this... Really appreciate your work
Love your capability to explain so simple! Thank you so much!
you are a really hard working teacher, thank you and keep going. great videos.
Excellent explanation with the animation. excited to see more videos.
This channel sure needs some recognition
I'm a retired electrician and we usually changed bearings in small to 250 HP motors. Still amazed that when I started back in late 1960's most NEMA motors still either had a zerk fitting or threaded hole to install one to decrease ball bearings. Amazed how long some sealed bearings may last in motors t hug at run 24/7.
Your videos are really helpful for me in DME
This Video helped me with my Bearings Exam. Thank you
Great educational vid on bearings. Thanks and keep up the vids.
Hey Adam, I learn a lot from your videos...nice efforts....Hope to see some detailed video on both type of bearings..I would also love to see some video on lubrication management ...take care
Short and simple but very informative. Keep them coming man. I am already subsided to u. Don't u dare disappoint me.
kindly come up with videos every week!!
Better than actual school education! Many thanks...i need these info for my job.
Great video. Great information and very easy to watch. Great job man!
Brilliant - all very clearly explained thanks :)
can't praise you enough
Could you do a video on valves and their types functions and so on.Recetky worked in an internship and I've been seeing these things alot
please upload more videos .............. waiting for next machine tech videos ..... i just love it ....please please upload
Great video! I really appreciate all your videos; you do a great job. If you don't mind, I would like to comment on a couple of things. Folks who have little or no experience have never heard the term anti-friction bearing as it has kind of become a legacy description. It is entirely accurate and acceptable, however I started using the term "rolling-element bearings" because people tend to understand that term better. Two small nit-piks: You said shielded bearings are lubed for life. That is not true. Sealed bearings are lubed for life but shields are actually installed to prevent over-greasing of the bearings. The shield is always on the side of the bearing where the grease is introduced to the bearings (shields can be removed for oil-lubed bearings). Also, angular contact bearings can be installed back-to-back, face-to-face or even tandem depending upon the application. Almost always they are installed back to back in pumps. However, face-to-face is better when misalignment is present (per SKF). Love the Chesterton 442 Split Seals on your pump!
Adam, Thank you for this video. Just getting into the bearings market. Is there any way we could speak in more details?
hey Adam, thank's man . it's extremly usefull i loved it.
Thanks a lot for this nice explanation!
thanks very much for sharing. What are the outer side ring and inner ring being made? seamless alloy steel tube or casting?
This is a great video. Subscribed. I hope to see more videos like it.
damn good video. Question. So I have an old fashion windmill with a horizontal shaft and 2 sealed bearings. If I wanted to have the shaft to turn more freely, to help with low wind start up, less torque required, can you recommend a better bearing??
Very thorough!! really easy to understand
Sir I've completed my mechanical engineering after now am working mechanical field now am learn pumps and motor sir happy to learn this and watching ur video s
Yes I did learn a lot, thanks!
Great explanation... Thank you very much
This video must have taken a lots of production hours. But very good explained the concept.
Where we can find FULL Lecture/Video on Bearings ??
hey you described very well. thankxx bro..
Thank you for sharing knowledge
Another great video.
Superb explanations
Thank you so much. Your videos are to help full for me
Wud like to know about tilting pad journal bearing working principle and when high temperatures issue comes
Nice summary ❤️
Thanks...very well done.... I use these for my grade 9 thru 12 power tech and auto classes.
That's exactly what I hoped! I'm glad other educators are finding these videos useful.
Perfect!! Many thanks sir
Well done. Nice video.
Can you make videos on turbine internals and compressor internals such as seal gas system, turbine governing mechanism, safety valves, surging etc??
Hey sir. I see your video is 3 years old. I don't if you're still around but I have one question. I have one pump and one pressure washer both electric, both have zerk grease fittings for the motor bearings. Some people told me not to grease those because I might cause damage. Is that true? If it's not. What kind of grease should I use?
Can you do a video on bearing number designations
great video, can you link me or make a video how to calculate bearing size. Thanks.
Great work
Just awesome
great explanation!
Wonderful video. 🙂 Can you please explain how one would decide whether to use hydrodynamic bearing or anti-friction bearing for a given application.
Answer is simple: Depends on the application
Great video! Thanks a lot.
Great video! I learned things! 👍 😊
So Tapered Cylindrical bearings are the best ones..got it
hi,can you please tell me what type of bearing have long life in vertical wind turbine?thank you
Why i didn't find this channel earlier.??
Me too😭
Please kindly share the knowledge about turbochargers
Thank you KZhead recommendations
Whats meaining of anti friction bearing i think all bearing are anti friction like sliding surface and rolling contact also
5:25 the middle one. Is it okay to weld the bearings?
Very good video. Keep it up, guys!
nice footages
Please make a video on axial load thrust load, radial load ,..so I can understand better.
I thought all bearings were anti-friction bearings. Isn't anti-friction the reason for using bearings?
Thank you so much for making these videos
I thought in a bicycle wheel hub the ball bearings are loose (not locked into a cage) ?
Thank you very much !!!
Great video! Very informative. Looking forward for more
:-) :-) I like your Krombacher Cap. It reminds me of my home village.
This guy rocks
Amazing!!! Love a good channel before it gets overwhelmed with earthlings ^^
can you please do the introduction of bearings pleaseeee 🥺
good stuff.
Very useful to me .
رهيب ...شكرا
I love my wife's hydrodynamic bearing, it supports the axial and radial loads of my shaft very nicely... ;) How the hell does this guy say these things with a straight face? XD
Engineers are all dead inside. They have their sense of humor, personalities and souls beaten out of them throughout the entirety of their academic lives.
Ask a mechanic about suck squeeze bang blow.
Ah, the good old 4 stroke, though in practice you need a lot more than 4 strokes to get anything done.
Nice Sir...
Pls add about babbit bearings
No words👌
Loving you guys , thank you.
Conical roller bearings are often used to support the wheels of cars.
I'm your big fan
Bushing engineers would like to have a word about your definition of bearing
nah. bushings aren't bearings, and bearings aren't bushings.
what the...? do they sell krombacher in the usa??
Hi, Gigaguenther, Adam here. I lived in Berlin for some time and was given that Krombacher hat as corporate schwag. Guess I was a valued customer...
Gigaguenther they sell krombacker in Ontario Canada. I pick it up from time to time.
Thanks
perfect video, thanks for sharing
Well, I think 3 things define a bearing: 1. support a cylindrical shaft for rotation or swing; 2. an independent component between shaft and structure; 3. lubricated (or prevent direct friction) Bearings do the 3 things you mentioned, but so are other machine components, e.g. rails, pulleys But to be more general, linear motion supporting element sometimes is also called bearing, such as linear guide can be called linear bearing. So point#1 can be generalized as "support an element's 1-DOF (degree of freedom) movement"....but that won't be nice to put this long string on youtube clip...
Thrust bearings?
It was proven years ago by crankshaft manufacturer SPG that a correctly designed oil fed plain bearing had less friction than a roller bearing or ball race, this related to the roller bearing crankshafts.
