Learn About the Basics of Ball Bearings, Needle Bearings, Tapered Bearings

[@almostbutnotentirelyunreas166]

Many YEARS of experience talking here, always good to watch a true professional at work!

[@johnjoyce]

Brilliant and amazing the human capacity to absorb sheer volumes of information so specialized and yet communicate it so rapidly, and with such a natural, every-day delivery interwoven with the precise terminology. Great audio and video quality too. Thank you.

[@johnsaum1260]

I worked at a transmission shop 35 years ago and fixed a lot of manual boxes as well as automatics. I thought I knew everything about bearings but you showed me a couple of things I didn't know. Thanks

[@realcotnoir2521]

hi! Paul i have gain my life at selling bearing 40+ years and going , i am on the industrial side of the bearing world and you in the automotive side , it is very different, you just gave me detail of bearing that the automotive as that we do not see in the industrial . With your explanation today , you gave me answer to some technical detail ,that i was never explain before in any course that i had over the years. It is very much appreciated that guys like you give your time and mind yourself at explaining and helping others by giving your experience of work . Thank-you! Very much Paul.

[@GearBoxVideo]

Appreciate that. Thank you. I started as a mechanical engineer for industrial power Transmission components so having to sort thru pages of bearing specs and calculations was part of my daily work.

[@SMOBY44]

Thank you. Always great to hear from someone who really knows what their talking about. You earned my subscription!

[@dougankrum3328]

I've been working on all sorts of mechanical equipment since I was 12-13...I'm 71 now, and still found your video worth watching..!

[@GearBoxVideo]

Thanks!

[@TopNotch50]

The Conrad-style ball bearing is named after its inventor, Robert Conrad, who was awarded a British patent in 1903 and U.S. patent in 1906. Great video!

[@GearBoxVideo]

TopNotch50 thanks for that information.

[@fasteddie4107]

Great info. This is the most complete explanation of bearings I have found on KZbin. Thank you for sharing your insights.

[@v1jilante]

Your technical explanations are fantastic. Thanks for the bearing knowledge deep dive.

[@Kenisproactivehere]

Serious information overload but well appreciated. I didn’t know what I didn’t know, but every explanation of yours made sense. I really appreciated your video.

[@onetireonfire2777]

HD mechanic here. This was a better presentation than I had in trade school, bravo!

[@kpratik5551000]

Thank you very much. As a mechanical engineering student (India), this practical knowledge helps me a lot because books don't show how actual bearing works.

[@GearBoxVideo]

Dated 12/21.21 Don't buy royalty free music because eventually someone decides they don't want it to be royalty free 4 years later and what to try and make money from my videos. So sorry about the weird music. I had to replace it or lose the money I make on the video.

[@DavidHerscher]

Wow, that is crazy. people suuuuuck.

[@rickfearn3663]

Outstanding clarity of explanation AND photos. Thank you.

[@saulwarren9611]

Wow, thanks a lot. I'm actually shocked to learn how vital bearing are, there uses & unlimited design variations to suit a desired purpose. You're information helped me decide that I'd need both hybrid radial / axel capacity for a few aerodynamic projects. In principle they are mostly the same, only it's the subtle mechanical designs that makes all the difference.

[@LS87B3]

Never would have thought I would enjoy a video about bearings. Now it's no longer a mistery how they work. :)

[@Diligent_Tom]

Every time I watch one of your vids, I learn so much. Thank you so much!

[@GearBoxVideo]

Thank you!

[@Ademann]

Hi, I've been working on repair manuals and automatic transmissions in Germany for more than 30 years, but I always find something new in your videos! Thank you!

[@gavinchusunrisesgrouplimit2084]

I work on supplying bearings for industrial and autombile bearings for over than 30 years. Watching this video repeatly and do learn quite a lot from this videos. Thanks for sharing.

Thanks.

[@akallio9000]

I've been a mechanical geek for 40+ years and all this is new to me. Mind blown! Thanks!

[@kturek625]

OMG - That was GREAT! Everything I every wanted to know about Bearings and their failures in 24 min! Ton's of examples and tips and tricks. good job, SIR!

[@Krzywoprostydezerter]

Nice and simple explanation. Many of technicians don't know which bearing is better for specific applications, they rely only on ready-made information from catalogs. Good Job Mister

[@GearBoxVideo]

Thanks 👍

[@freeinhabitant2422]

Not only for transmission use, but machinery of all types - very nicely done video - thanks!

[@sama.7870]

...I've wondered how the ball bearings got into a caged unit for years - the first minute of the video explains it perfectly, thanks!

[@ensidfkgnur]

Fantastic video! No 2 minute heavy metal intro with explosion, just got right to it with great visual examples of everything you talked about. Thank you for posting this and hopefully future gearheads will watch it and see that the Devil is in the details! (chamfered inner race, snap ring slot size, etc)

[@DM-rp7ps]

Another terrific vid! I've learned a heap from Paul so far, and am not done yet. Had the honor of speaking with him, he actually answered the phone as I was placing an order, and comes across as a true gentleman. Thank You for your dedication to the channel, the store, and the book is an excellent read! I'll definitely be back for more parts as I tear into two more. PS: At 2 AM you should be asleep man, not answering emails...

[@GearBoxVideo]

Well said!

[@remington351]

Hi Paul. I just found your channel and I gotta say it's pretty awesome. I've been a shade tree mechanic for the past 20 years and manual transmissions always seemed a challenge to me. Your videos are awesome and so informative. I'm learning more theory and practical application knowledge from your videos than I ever got from my brother who's a mechanical engineer.

[@westwoodtriumph6433]

Holy crap your experience and explanations are perfect.. I would like to sharer with my like minded brothers that you should always clean your new open face bearings.

[@fire7765]

The power of knowledge, thx for sharing.

[@smjones4238]

You, Sir, have some major experience. It shows... This makes you a very valuable resource in my book. Thank You for sharing. I subbed a while back and have enjoyed every video that I have watched. Michael in Colorado.

[@TheEZGZ]

Thank You Paul. Well done as usual. Fastest 20 minutes of my day. I got a lot of answers to things I wondered about. No substitute for experience.

[@TonyRule]

I disagree. Experience is useless without some understanding the underlying theory - otherwise you can form the wrong conclusions as to why things happen.

[@stevemiller6766]

Paul these are great videos, I just discovered you content. High school auto shop instructors should make these mandatory viewing. thank you sir.

[@GearBoxVideo]

Thank you for that.

[@gregkimura5906]

Again, great job. Excellent explanation about forces on bearing surfaces and design of bearings!

[@01jc080]

Very well done. I have 30 years experience working in the bearing industry. Keep them clean. Install them properly (pay attention to how they come out). Keep them lubed. You will be fine. Do you ever have problems with magnetism from tools or work surface? Avoid that too I suppose.

[@GearBoxVideo]

I haven't had magnetism issues

[@garthrichert5256]

Thank you for all these helpful videos. It takes a lot of work to make them, besides your normal job. Most appreciated.

[@josephsparks5770]

I regularly repack my trailer wheel bearings, I know I will do a better job now, and inspect them correctly! Yes, sadly, I am so guilty of not changing my manual transmission oil, until about 140,000 miles, that rebuild looks a lot more likely! And it's really easy to do, no excuses. Thanks!!!

[@charlesmiller7139]

Thanks. Very good info. Working on a friend's ranger with a manual. Both front bearings were toast. Was suppose to be just a clutch job. It's nice to see an explanation behind wear and failure of bearings.

[@oby-1607]

Very informative. Bearing design is so important and yet disregarded.

[@HB-yq8gy]

I didn't have a press to remove the hub so I repacked the bearing with red grease for a John Deere 332 PTO clutch from 1988. The seal bearing was dry out started to get burnt a little & didn't engage with electric pto switch. I cleaned it out real good with thinner & air compressor removed & clean out crud. It feels & looks like new! Your thoughts some guys say not a good idea but, works fine so far.

[@atcjoe1600]

My wife sees me watching this stuff and says “ I can find you something better to watch “, and I say ,”but I like this kind of stuff”.

[@nagato8152]

*you're a man of culture, i see*

[@mikeadkins4727]

Dynamic loads are nothing more that the load rating while the bearing is in motion. Static is stationary, dynamic is in motion. The combination of radial and axial loads is simply called combined loads. Conrad construction is the assembly procedure named after the Fafnir employee that patented the process. I am a Sr. Technical Analyst ( I am the person that answers bearing questions for a large bearing manufacturer).

[@GearBoxVideo]

Good to know. So given an example of a standard 6307 as opposed to a Max 307 in high thrust load applications are you saying since the combined loads will always be better with a Max bearing that we should ignore the failures seen using max capacity bearings in transmissions with high thrust loads and ignore the engineering changes both General Motors as well as Borg Warner made going back to standard Conrad bearings... Please explain. Should the specs in the original New Departure data sheets be ignored as well? Sometimes combined load doesn't cut it because the loads should not be combined in the first place especially when using certain engineering practices related to gear train design. We are talking radial load , axial load, dynamic load here. I know what static load is.

[@dannyr333]

Hey there watched ur video I have a question I have a road bike with I believe 6082 bearing sealed now from the factory the bearing are greased and sealed however they might roll smooth they are grippy and tight they dont flow or spin easily... now do you think the bike builders knew what they what were doing (these were 700 dollar carbon wheels ) in terms of do bearings for the rear wheel have to have a LOAD on it for it to spin in a faster rotation cuz the front wheel spins freely and loose... I'm about to take out the bearings degrease them and just lube them with some t9 lube and put them back in with no seals I know they won't last as long but the wheel seems like the grease on these bearings is creating more friction where the goal is to create less friction... so my questions is do you think I should do a bearing cleaning job and put them back in??? as long as I keep opening up the rear wheel hub to see how they're doing I think that is what I do thx for ur time brother man Peace Daniel tampa FL

[@GearBoxVideo]

I replied to this some where else. Anyway I said remove the seals, clean em up and repack them and reinstall the seals. I would want any debris locking up my bearing hubs

[@dannyr333]

@@GearBoxVideo thx for responding when you say repack them... is it still okay to just lube the bearings with a chain lube (t9 lube a very thin oil) and have no seals on them? My goal is so the wheel will spin faster and without resistance even if I am sacrificing the bearing vulnerable to dirt etc etc I think I'm just wanting someone to agree with me who has better knowledge than I do... i am willing to be wrong about the whole idea though.... peace dude

[@davejohnson171]

Well, where is your channel, Mr. Bearings Einstein ?

[@samholt2062]

That was an amazing explanation of the difference bearings amd their strengths and weaknesses, you actually helped me assess a slight misalignment issue im havingin my transmission its been racking my brain for about 2 months but watching this video gave me a better understanding on why im getting the noise and vibration with such a new clutch. Thank you 👍

Hello Paul, Very interesting and informative videos. At 68 though I think the only thing I'll be doing now is lube changes. Had the rear output shaft Ball Brg on my 78 Mustang 4 spd fail once. I managed to decide what part to buy in advance just by careful observation of how the noise was related to engine speed, gear selection and vehicle speed. (It only varied, changed frequency as the vehicle speed varied). When I changed it was obvious the inner race was the problem with a pitted area about 1" long. My next door neighbor at the time was a metallurgist at Chrysler in Highland park MI and he said "give that to me and I'll see if we can see why it failed". When he brought it back to me, they had sawed out a piece of the inner race, mounted it in something that sort of looked like Bakelite and the cut surface had been polished to a mirror like finish. He told me they had put it under an electron microscope and that it had failed because of foreign material in the steel of the inner race. I never dreamed that he would go to those lengths to get an answer.

[@GearBoxVideo]

Thus the decline of the American bearing industry.

[@pasqualeponterosso1956]

Hi Paul, Thanks for a great video. Really appreciate you putting some of your (obviously huge) knowledge out there on the internet. Didn't know there was so much to say about automotive bearings. Knowledge/experience plus good communication skills makes for a great teacher, thank you.

[@jc-botaman1077]

Excellent video! I will be recommending it to people when I'm trying to explain bearing types and they look at me like I'm talking martian. You covered one point I've been having trouble explaining without me actually having the bearings to show people, max-capacity vs. conrad. Again excellent, Thank You.

Great job, straight forward, your knowledge past on to us without our knuckles and fingers getting cut and pinched, lol lots of that over the years. Thank you for your great professional knowledge, I always prefer to take knowledge from a hands on guy then a person with papers and no hands on experience. Thanks again.

[@5hoopuf]

jim smith As an engineer with only limited hands on experience with the abundance of design cases Iˋve been faced with over the years I eally appreciate videos like this, with people who know a hell of a lot more about certain components than myself :) Iˋm lucky that I often get to build what I design, and I totally agree with you, that being all papers and no hands sucks. Books and charts are good, but hands on experience really locks it down and gives you the "feel".

[@GearBoxVideo]

What I've been saying for years. There are extremely talented engineers out there. What I tend to see is an inability to connect the dots. The ability or perception of one to see 10 steps ahead of the single design. How the single component effects other components. A good example would be someone who designs a stronger gear tooth that seems OK however when run in a transmission it causes a higher separation load and blows up.

[@nraynaud]

I did a quick googling of "max capacity bearing" (never heard of it before), I stumbled on an emerson page stating: "This makes them ideal for applications requiring heavy radial loads and low speeds where thrust loads are comparatively low." I guess the key words "low speed" go with your remark about heat. Thanks for the knowledge.

[@GearBoxVideo]

People don't believe me and insist on putting these in transmissions that produce thrust loads

We used to refer to the tapered roller bearings as Timken bearings in reference to the original manufacturer or inventor. Great video by the way.

Yes I believe Henry Timken was the inventor. Timken bearings are now made all over the world. Problem is when you get them they are made in several countries. We have been using Koyo mostly because that is the current choice of most OEM applications.

[@CheezyDee]

Mopar Performance used to sell an offset dowel kit for alignment issues, mainly to prevent premature pump/converter bushing wear and converter drainback issues in automatics but I assume it could work for manuals as well, as long as the shafts are offset but still parallel.

[@GearBoxVideo]

+Cheezy Dee There are quite a few companies that sell offset dowels in varying offsets.

[@jcadlols]

One trap I’ve found with tapered roller bearings is that the inner race can have significant wear before visible issues with the rollers or the outer race. I found this when replacing bearings anyway & I cut the cages off to use the inner races as press tools. Do you have any order of brand preference with bearings?

[@GearBoxVideo]

Koyo or NTN. The Timken stuff is good but most are no longer made in the USA anyway.

Needle bearing should also have its thin internal ring. Good information provided. Thanks.

[@GearBoxVideo]

Not necessarily true. Inner ring or race can be an integral part of the gear or a shaft raceway. Often times you can purchase hardened inner rings to press on shafts that have no heat treatment.
