Operated lathes and other machine tools for a long time. I never saw steel melted on a lathe before! Wow! I can understand wanting to make a $500 repair into a $20 repair but holy moly! The ID, OD, heat treat, radius of the race, and tolerances are now unknown. Hope whatever it is used in doesn't spin fast!
yea came to post this. not even an engineer but this is dodgy as hell. The steel used in a bearing is very specific, and heat treated, just replacing it with weld doesn't make it new again.. there is just so much wrong with this :( Welding using the lathe though.. goodbye bearings!
i knew i would find this comment i dont even know where to begin on how bad this was you can see at the end when he picked it up in the middle how sloppy the tolerance is now 😂

well it depends on application. That bearing new probably about $1k. Pack it with grease and it will roll a large shaft better than a bronze bush. Put the repair / join not on the thrust side and it will hold decent load. It can have a purpose, and for under $1 total cost does have its place and does have a use.
@@joey66436 If the application required a roller bearing rather than a simple bush, then it is unlikely the repair is good enough. In any case the bearing is now in worse shape than it was before. Before it was just worn, now it's worn and has grossly improper clearances.
@@keithammleter3824 it was cracked. the clearances are better now than when it was cracked. The clearacnes could be better again if they just v'd out the crack and weleld it closed. My point is it still has use.
@@joey66436 : Cracked? It's a dead straight line. What would cause it to crack in a dead straight line? More likely it seized due to dirt or brinnelling, and they cut it so they could disassemble it. The inner housing has rotated on the shaft.
These guys have a winning formula. They do absurd repairs when they aren't busy and film it for UA-cam. There's nothing controversial so they don't have to worry about demonitization. People comment on the videos due to their absurdity, which the UA-cam algorithm considers engagement and consequently boosts their recommendations.

When welding on a lathe, always attach the ground wire directly to the workpiece. Otherwise you will damage the bearings of the lathe. Greetings from Germany Paul
Now I have seen everything! The bearing outer has been cut (presumably with a cut-off disk), so part of the circumference is gone. Then he closed the gap in the lathe, welded it up (shocking weld quality), and machined the inside - God knows what the inside diameter now is, but it sure won't be right. He's machined at least several thou of the outside, so the bearing would not in any case fit properly in wherever it is supposed to go, but it won't anyway because he closed up the cut. He relied on the chuck jaws for mounting it square in the lathe instead of using a dial indicator - very poor practice - especially the way these guys treat lathes. And, after putting the old, worn, rollers back in, he rolled it on a table and gave a thumbs up! Yet you can clearly hear the rollers rattling around within the now oversize housing - something that should never happen. In short, he's turned a worn out bearing into an utterly ruined bearing. And by the way - he's a maniac dangerous to himself using the angle grinder in and out of the rotating job and without any eye protection.
@@Ihavetruth22 It's not even good for a waste water pump. It's only good for melting down. Did you notice the icing on the cake that I forgot to include before?

it wasn't cracked, it was cut with an angle grinder. The rollers are all pitted, the race is pitted, the temper has been taken out of the body, it won't last five minutes.
@@ctiley2212 it was cracked, there was no material taken off with a cut off wheel, if it had been cut, when they squeezed it together, the bearings wouldn’t fit because the diameter would be smaller.. they used a hard welding rod, so it’s probably ok, and it depends on the application, if it’s for a knuckle on an excavator, then it’ll last forever, if it’s a main bearing on a turbine engine, then it won’t last long
Since they didn't but the earthing clamp directly on the outer race, they electrocuted the internal bearings of the lathe. 10 more times and they can repair their lathe bearings
Wow! Engineer with 35+ years experience in heavy-duty machinery here. This goes against any common practices! Bearings are manufactured to mue-meter tolerances and assembled in clean-rooms. The races undergo a special stress-relief process to keep them from cracking. That type of ‘repaired’ bearing could only work in a low load, slow speed and non-critical application. Would be interesting to see what type of equipment this one went into.
They probably don't have the word "precision machinery" in their dictionary.And they and they have only 3 kinds of mechanical materials: iron rods, iron blocks, welding rods.
It is not surprising that the death rate in this country is so high, since even a bearing that qualifies for replacement and probably corresponds to the operation of some large mechanism, can be cut with a grinder, welded with an electrode and rolled, convincing yourself and viewers that the job is professionally made and the bearing is like new.
Retired welder (12 years on buildings, bridges and pipe(uphill)) and 8 years welding inspection, nuclear power plants, I am appalled. Whatever this bearing went into, I wouldn’t bet on it lasting till coffee break.
Тот самый случай, когда лопнутая обойма подшипника, прослужила бы больше без ремонта))). Лопнула обойма подшипника из за неправильной посадки, если его установят туда же где он был, то результат ждать долго не придется.
Скорее не лопнула,а они сами её разрезали,дабы сжать патроном,чтобы зазор между внутренней и наружной обоймами сократить. Люфт убрать. Потому что,когда обойма лопается,остаётся трещина,а у них там 3 - 4 мм
Wasting time and money the work being done is mickey mouse jobs, SKF Spherical Roller Bearing are made in very high technology and the internal clearance is very precise.
In Pakistan, lathes are ironworking equipment.Having a lathe makes them feel more professional. For Pakistani ironworkers, iron is iron, they have no concept of mechanical engineering. Because of this, there are very few real professionals in that country who can expose those fake major.

Clearly this is all a joke, a parody? No one can seriously believe that a bearing, a highly precise piece of engineering, can be repaired with a lathe, grinder and welder? What a great joke.
Possibly was made to get cheap content for the channel. What troubles me is the lack of safety gear for a bloody youtube clickbait video. They welded without gloves or skin protection, angle grinded without eye protection or blade guards and spun suspect welded lumps of steel in a lathe with no safety shields what-so-ever. People could have gotten maimed or killed for a few views.
@@wombatillo You are correct. Some UA-cam channels in South East Asia have similar content although it is more about restorations of equipment. Someone made a documentary about it, and it was explained that no matter if people like the video or call out the bull shit which it is, the channel owner still earn money because of click bait. And yes, those sandals and invisible safety glasses are great. Plus the clean sand all over the floor….

The cost of a new bearing is going to be less than what it would cost to replace this repair. When it fails ( which it will ) you'll end up having pull this and put in a new bearing anyways. I know it must be difficult to get replacement parts in this part of the world but sometimes its not worth the hassle.
This is Pakistan. Not as easy as most country's. It leaves me shaking my head too. But I guess they work with what they have. And labor must be dirt cheap is all I can figure. I can not imagine this bearing lasting that long,
A similar size bearing to that made by SKF and sold hear in the UK is around about £700+ VAT. I bout a load of stuff at a bankruptcy auction and there was abrand new bearing similar in size and I was amazed at the cost. I sold it to a firm and made a profit. No way could you buy a bearing that size cheap. These guys do their best because that is what they have to do. Here in the West, our rules demand new, our engineers demand new. I don't know how long the repair in the video will last but if lasts for a while before breaking then it has saved some money.
My welding instructor always hammered home the need to place the ground clamp on the actual piece of work to be welded. This way the current does not pass through the bearings on a machine, especially a lathe.
Don't worry, saw the label, most probably made in Pakistan too. If it broke, they just weld it back. If the motor fail, they'll just rebuild it. If they need parts, they'll just cast or forge it. These guys are great in self reliance.
Amazing weld repair here. I noticed the guy was using the sander on the inside of the circle that the bearing rollers will roll on and these are normally measured to an accuracy of less than one tenth of a mm ……will that not make the bearings have too much play ? Perhaps it will not matter so much if it is for a large slow wheel rotating machine. Once again the guy on the Lathe did not wear Eye protection …..! Thanks for sharing.
This video is fake guys, they're not actually using the bearing. They make it obvious at the start when the bearing stands out as clean in the pile with a clear cut mar through it.
I think the idea on this one is to fix it and sell it on to someone who doesn’t know any better. Hence more effort to polish the outside than to fix the actual race surface
@@chrisjarvis4449 wow what a truly deep dive comment......I totally got that refetence though.......1000s of emojis in my phone and not one of a smiley face with a fez hat LOL.
Those rollers and rolling surfaces must be shiny like chrome, on this bearing they are matt, bearing is worn out, usless. And hairdoo guy is going to guess internal geometry, eyeball it? Only way to weld hardened steele in bearing quality is to put it in furnace, heat it up to white heat and let it cool down slowly. We are calling this releasing. Then preparing gap and welding it with proper tehnique, preheat, ect... Now machining and finaly heat treatment.
Don't mind, they intentionally cut it up with an angle grinder to make a content on how they fix it. It was not supposed to be used further from the beginning.
So they basically risked the lives, skins and eye-sight of their workers for a few cheap views on youtube? That is bloody amoral but I guess that's how they roll in Pakistan.
You know I love about these restorations is they only need to look good. I would love to see this bearing installed into a high load application and see it shit it's self within 30 seconds
The lathe looked clean and relatively new compared to the sort of equipment we usually see in these videos. Shame you just destroyed the bearings in the head stock by welding through them.
Recycling at the quantum level. Beyond our understanding in the western hemisphere, Next time I buy a bearing,I,ll appreciate the work gone into it,Like the meticulous devotion to cleansing,Choice of the best metallurgy science know to man ,And the 24,000 mile or one hour ,what ever comes first no quibble,No money back guarantee. Personally backed by the Ali bongo brand name.
I’m not sure why you would ever grind all the way around a bearing shell. Except to make it look prettier. And cover up the welding marks. Awfully dubious.
Ювелирный электрод, прецизионная болгарка, токарь с кувалдой - это, конечно, очень профессионально. Но главный секретный процесс остался за кадром. Все решает толщина реза обоймы подшипника. Разрезал, сжал и зазоры износа на роликах ушли. Короче, восхищен, зачарован, покорен. P.S. Интересно, токарь знает, что у него там, сзади на стене висит, или это для красоты?
I have seen a bearing split with a sharp edge like that but all around the middle of the outer race. Can I suggest that the way it has failed might be indicative of the way it was produced.

they used a hard welding rod, so it’s probably ok, and it depends on the application, if it’s for a knuckle on an excavator, then it’ll last forever, if it’s a main bearing on a turbine engine, then it won’t last long
@@danhard8440 no
Since they didn't but the earthing clamp directly on the outer race, they electrocuted the internal bearings of the lathe. 10 more times and they can repair their lathe bearings
OK, now, I want to see one of their brain surgeons at work!
Probably perform surgery with this 🪓

Это тот самый подшипник, на котором они вертели здравый смысл?
Wow! Engineer with 35+ years experience in heavy-duty machinery here. This goes against any common practices! Bearings are manufactured to mue-meter tolerances and assembled in clean-rooms. The races undergo a special stress-relief process to keep them from cracking. That type of ‘repaired’ bearing could only work in a low load, slow speed and non-critical application. Would be interesting to see what type of equipment this one went into.
They probably don't have the word "precision machinery" in their dictionary.And they and they have only 3 kinds of mechanical materials: iron rods, iron blocks, welding rods.
That would be, the trash
Not my Chinese skateboard bearings. lol
They did dismantle it on the clean room sack and not on the dirty floor!
'Clean rooms'?
Didn't you see him shake the hessian bag before putting the bearing on it?
I think I have finally figured it out. PK Restoration pays these guys to do stupid and ridiculous things????
It is not surprising that the death rate in this country is so high, since even a bearing that qualifies for replacement and probably corresponds to the operation of some large mechanism, can be cut with a grinder, welded with an electrode and rolled, convincing yourself and viewers that the job is professionally made and the bearing is like new.
Not quite sure what I just witnessed....
So many things wrong with that I don't even have the time to comment on it all.
При пррсмотре этого видео сначала доктор Дью лопнул от смеха, а затем обойма подшипника... мимо шва
😂😂😂😂😂
Retired welder (12 years on buildings, bridges and pipe(uphill)) and 8 years welding inspection, nuclear power plants, I am appalled. Whatever this bearing went into, I wouldn’t bet on it lasting till coffee break.
Тот самый случай, когда лопнутая обойма подшипника, прослужила бы больше без ремонта))). Лопнула обойма подшипника из за неправильной посадки, если его установят туда же где он был, то результат ждать долго не придется.

No.Its outer diameter has been reduced and cannot be assembled unless he uses welding.
@@kyvih9217 why doing such a dumb thing?
I'm from France, I don't get it.
In Pakistan, lathes are ironworking equipment.Having a lathe makes them feel more professional.
For Pakistani ironworkers, iron is iron, they have no concept of mechanical engineering.
Because of this, there are very few real professionals in that country who can expose those fake major.

С подшипниками тоже чюдили, но просто втулки переходные вытачивали... Было что наружнюю обойму использовали в качестве переходной втулки, сваркой крепили и обтачивали 🤣Доходило до того что и пальцы гусинечные наваривали ну или точили из чего придётся. Можно было все это достать... Но времени небыло) Технику до последнего насиловали... Но вот такое не приходилось делать 😅👍 Но их резцам конечно респект!

Тут в коне я с тобой согласен. Здорова кстати. Бывает под восстановление - всякое. Отец рассказывал,что в колхозе они из-за дефицита (90е) кору берёзы вместо вкладыша ставили. И похуй - работало. Но подшипник таким образом,да и под такой диаметр вала -- это пиздец!!!!!

@@thenextstepp let’s not forget the likely 7018 or 6010 or whatever welding rod they are using which isn’t even rated for that application anyway.
I m welding parts of bearings in places where there is much abrasion , great stuff and easy to weld
Well, looks like racing clearance to me. Tolerance is within a snot or 2, Do not worry about those weld canyons the rollers need to pass over. Won't chatter too much for too long. Mabey I can get them to rebuild my wheel bearing's on the mack?
Доо! Подшипнег же сразу отрыгнет после такого ремонта!
Я плакаль.....)))Він в зношеному стані був кращий ніж після ремонту))
What kind of damage is going to happen when put in service from the lack of precession. Did everybody see the amount of internal looseness the bearing had when he lifted it by the inner race
friend be careful he did the finish with the grinder for more precision 😁
BE KIND THE BEARING ONLEY HAS TO GO ROUND ONCE A YEAR . 🤣🤣🤣🤣🤣🤣 MAD AS HATERS .
The bearing was probably broken because of abuse, overloading and lack of maintenance.
@@gordonwelcher9598 YOU ARE KIDDING . I DO HOPE SO . MIGHT BE GOOD FOR A COUPLE OF TURNS . DO YOU KNOW ABOUT PRECISION BEARINGS. DONT THINK YOU DO TO COME OUT WITH SUCH TALK .
There are some things that you shouldn't do and this is one of them. I've seen birds crap out better beads than those not to mention its on a bearing FFS. The safety squints while grinding are great too, who needs safety glasses or even eyesight for that matter. If that spins over 10 rpm for an hour you'd be lucky
Thanks for the tutorial, it's much faster than any other method I came across.
That has go to be the best maintained lathe in Pakistan !!
Did you see the cross-slide jump back towards him for about 10mm when he tightened the tool? That lathe is well broken in - ehh - worn out!
Загнутый электрод заставляет ток течь по дуге, в результате совместно с обрабатываемой деталью образуется секторный дроссель , что стабилизирует сварочный ток. :)
Зазоры на собраном подшипнике впечатляют!!!
Они соответствуюк чистоте поверхности дорожек и тел качения а также качеству закалки!Вопрос только с гравировкой суффиксов!
солидол компенсирует зазоры
Lot of comments on quality but remember this is a country with low income and lot of old machines to restore. In their world it is fixed and thats it.
Interesting video 👍
Clearly this is all a joke, a parody?
No one can seriously believe that a bearing, a highly precise piece of engineering, can be repaired with a lathe, grinder and welder?
What a great joke.
Possibly was made to get cheap content for the channel. What troubles me is the lack of safety gear for a bloody youtube clickbait video. They welded without gloves or skin protection, angle grinded without eye protection or blade guards and spun suspect welded lumps of steel in a lathe with no safety shields what-so-ever. People could have gotten maimed or killed for a few views.
@@wombatillo You are correct. Some UA-cam channels in South East Asia have similar content although it is more about restorations of equipment. Someone made a documentary about it, and it was explained that no matter if people like the video or call out the bull shit which it is, the channel owner still earn money because of click bait.
And yes, those sandals and invisible safety glasses are great. Plus the clean sand all over the floor….

The cost of a new bearing is going to be less than what it would cost to replace this repair. When it fails ( which it will ) you'll end up having pull this and put in a new bearing anyways. I know it must be difficult to get replacement parts in this part of the world but sometimes its not worth the hassle.
This is Pakistan. Not as easy as most country's. It leaves me shaking my head too. But I guess they work with what they have. And labor must be dirt cheap is all I can figure. I can not imagine this bearing lasting that long,
It will probably serve in a small slow running merry-go-round for children. 😁
A job like that in Pakistan costs less then 50 bucks, so if it will work also for a few months it will be a good deal for them anyway
I read that there pay rate is 135.00 a month.
A similar size bearing to that made by SKF and sold hear in the UK is around about £700+ VAT. I bout a load of stuff at a bankruptcy auction and there was abrand new bearing similar in size and I was amazed at the cost. I sold it to a firm and made a profit. No way could you buy a bearing that size cheap.
These guys do their best because that is what they have to do. Here in the West, our rules demand new, our engineers demand new. I don't know how long the repair in the video will last but if lasts for a while before breaking then it has saved some money.
That is a pretty new and clean looking lathe he is working on. Would like to see it in a year
i was thinking the same thing
Don't worry. They will weld fill slides and repair it with an angle grinder. For jobs like this it will do, will be 'precise' enough.
My welding instructor always hammered home the need to place the ground clamp on the actual piece of work to be welded. This way the current does not pass through the bearings on a machine, especially a lathe.
I think, rather in two weeks...
Don't worry, saw the label, most probably made in Pakistan too.
If it broke, they just weld it back. If the motor fail, they'll just rebuild it. If they need parts, they'll just cast or forge it.
These guys are great in self reliance.
Как говорит Доктор, "в любой непонятной ситуации приваривай подшипник"
Az SKF cégnél néhányan beadták a felmondásukat miután látták a videót!
Ahaha
Зря варили, надо было на эпоксидку клеить
😂😂😂
SKF may learn from them.
Surely this is just a stunt for UA-cam views? Nobody's going to get any use out of that bearing all gouged up with angle grinder scars.
Amazing weld repair here. I noticed the guy was using the sander on the inside of the circle that the bearing rollers will roll on and these are normally measured to an accuracy of less than one tenth of a mm ……will that not make the bearings have too much play ?
Perhaps it will not matter so much if it is for a large slow wheel rotating machine.
Once again the guy on the Lathe did not wear Eye protection …..!
Thanks for sharing.
This video is fake guys, they're not actually using the bearing. They make it obvious at the start when the bearing stands out as clean in the pile with a clear cut mar through it.
I am really impressed with that shiny new lathe ! 😊. ❤
Sad to see people thinking they are doing a great job when they are only doing stupid things. This will fly apart and kill someone.
It's probably a slow rotation bearing
сварка через шпиндельные подшипники это прекрасно
Через неделю обратно но уже весь агрегат))
После всего сделанного, этот подшипник будет самым красивым на свалке!
Theirs many doubting Thomas's,but one true faith in working with what you have and not what you haven't
Welding hardened steel just creates a place for it to crack right next to the weld, and it's not a matter of if!
Красавцы, зарабатывают на просмотрах. Реакция яйцеголовых-- бесподобна.

Всё верно, эти обезьяны могут многое сделать и плевали они на допуски и измерительный инструмент. Это реально обезьяны - тупые да ещё и дебилы🤦
I think the idea on this one is to fix it and sell it on to someone who doesn’t know any better. Hence more effort to polish the outside than to fix the actual race surface

Может там уже такой же подшипник стоит?
И почему все считают что массу прямо на станину кидают? Обычно её цепляют на другой конец шпинделя и провод не мешает, и подшипники не страдают...
Those rollers and rolling surfaces must be shiny like chrome, on this bearing they are matt, bearing is worn out, usless.
And hairdoo guy is going to guess internal geometry, eyeball it?
Only way to weld hardened steele in bearing quality is to put it in furnace, heat it up to white heat and let it cool down slowly. We are calling this releasing. Then preparing gap and welding it with proper tehnique, preheat, ect...
Now machining and finaly heat treatment.
Who’s the biggest clowns them doing it or us wasting our time watching this rubbish
Yet we continue to do so
very big bearing 👍👍👍👍
Don't mind, they intentionally cut it up with an angle grinder to make a content on how they fix it. It was not supposed to be used further from the beginning.
So they basically risked the lives, skins and eye-sight of their workers for a few cheap views on youtube? That is bloody amoral but I guess that's how they roll in Pakistan.
You know I love about these restorations is they only need to look good. I would love to see this bearing installed into a high load application and see it shit it's self within 30 seconds

A NECESSIDADE.
The lathe looked clean and relatively new compared to the sort of equipment we usually see in these videos. Shame you just destroyed the bearings in the head stock by welding through them.
Recycling at the quantum level. Beyond our understanding in the western hemisphere, Next time I buy a bearing,I,ll appreciate the work gone into it,Like the meticulous devotion to cleansing,Choice of the best metallurgy science know to man ,And the 24,000 mile or one hour ,what ever comes first no quibble,No money back guarantee. Personally backed by the Ali bongo brand name.
I’m not sure why you would ever grind all the way around a bearing shell. Except to make it look prettier. And cover up the welding marks. Awfully dubious.
Ювелирный электрод, прецизионная болгарка, токарь с кувалдой - это, конечно, очень профессионально. Но главный секретный процесс остался за кадром. Все решает толщина реза обоймы подшипника. Разрезал, сжал и зазоры износа на роликах ушли. Короче, восхищен, зачарован, покорен.
P.S. Интересно, токарь знает, что у него там, сзади на стене висит, или это для красоты?
Во - во😂
Это, от сглаза, или на "удачу"
I have seen a bearing split with a sharp edge like that but all around the middle of the outer race. Can I suggest that the way it has failed might be indicative of the way it was produced.
