How incredibly repair broken bearing, took from scrap and make it works #Amazing #restoration #skills #process #mechanical #workshop @mimechanics1019
Очень нравятся их сварочные маски. Совершенно не нагружают голову! Держи себе рукой, и никаких забот! Восхищает смелость токаря. Работает без защитных очков! И правильно. От этой техники безопасности одни проблемы. И да, отремонтированный подшипник получился явно лучше нового.
Получился подшипник с хер пойми каким диаметрами, хер пойми какой закалкой, в котором даже на видео обойма в конце просто неистово болтается :D красивая игрушка и не более) Думаю, такой херней, как сварка подшипников, даже там все-таки не занимаются. Ну или мне хочется в это верить :D Судя по размеру изделия, применялся он явно на чем-то большом и дорогом, и будучи владельцем или ответственным за эксплуатацию подобного механизма я б таких "восстановителей" и на пушечный выстрел не подпустил бы к технике))
Загнутый электрод заставляет ток течь по дуге, в результате совместно с обрабатываемой деталью образуется секторный дроссель , что стабилизирует сварочный ток. :)
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 RU-vid. There's nothing controversial so they don't have to worry about demonitization. People comment on the videos due to their absurdity, which the RU-vid algorithm considers engagement and consequently boosts their recommendations. They make about $3 to $5 per 1000 views, so far they made about $400 which then gets converted into their local currency. Over time they probably make a few grand per video. I wouldn't be surprised if they are making more on RU-vid than on their day jobs.
сварка обоймы подшипника без предварительной разделки, без отпуска и явно без последующей закалки, рутиловым электродом🤦♂️🤦♂️🤦♂️. я бы за такую работу ни цента не заплатил! ещё и сварщик опять с гнутым писюном. выключил на четвертой минуте, считаю просмотр данного ролика пустой тратой времени.
The Indian population is among the biggest on earth, so a life lost here and there because of 'reconditioned' hardware by Indians would probably don't hurt too much...
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? They cut it right over one of the 2 lube holes (that's what the groove is for - so that you don't have to install it with a lube hole aligned with the housing hole) So, if it is installed and they tried pumping in grease, it's going to be extra hard to get the grease in.
@@Ihavetruth22 Yeah... The errors here are so egregious that the only conclusion you can come to is that they made this video to trigger us first "worlder's". This "repair" is so effing bad in a multitude of ways, it's the only explanation.
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.
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.
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.
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
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
After using the lathe tool to destruction and then uses a hand grinder with lathe rotating..obviously he knows an orthopedic surgeon who can put his arms back on . Total suicide.
Как токарь могу сказать - нихрена станку не будет, главное чтобы окалина не спалась на станину. Кстати, эти станки времён царя гороха будут работать ещё лет двести, не меньше. Это на росийских станках с китайской электронной начинкой варить нельзя, сгорит вся "электроника" 😂😂😂
@@Bosjak63 Ну возможно вы никогда подшипники в шпинделе после такого не видели, но масса приконтачить может в любом месте, хотя если так ремонтируют подшипники у них, то конечно похрену там на всё.
@@Myxin23 На своём 1А62 Станок токарно-винторезный универсальный я никогда не видел этих самых подшипников, потому что с момента его выпуска в 1953 году он ни разу не ремонтировался А что на нём вытворяли, такого вы точно не видели. Когда совхоз развалился, я хотел его выкупить но мне не дали, и в 1995 году тупо сдали в металолом ...
Я смотрю австралийского ремонтника, что тяжелую технику ремонтирует. Он тоже прихватки на станке же делает. Обваривает, конечно же, на специальной площадке. ru-vid.com
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.
1991г. Лесозаготовка, Алтайский край... Всякое вытворяли) и шестерни наварили, вкладыши из баббита вытачивали, потом половинили их, шаровые/наконечники рулевые вытачивали, коленвалы наваривали... 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!!!!!
Самое интересное что в этих видео только русский человек обстоятельно , и с критикой подходит к ихним творениям . Остальные нерусские коментаторы взахлеб хвалят процесс этого производства .
@@user-ty3bo1ls6v Так откуда им знать как по-настоящему? Что привезут в воллмарт, то и берут. Может думали раньше, что подшипники на дереве растут, а тут такое откровение.
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
@@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 .
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?
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
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.
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 RU-vid 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….
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.
Работал на ГПЗ 11,потом инструментальщик ом на МЧЗ " Луч" .Сварка ШХ15 потом откатные работы с твердостью 62-64 единицы,дичь.Развалится сразу,без вариантов.🤪🤪🤪
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.
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.

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.
Welding in flip-flops and angle grinding on a live lathe. Also notice no wheel guard on the angle grinder or eye protection on the user. This is some serious OSHA nightmare fuel. Human life costs nothing in this place.
If it was preheated and the used lowhyrogen rods then destrested it in an oven maybe yet if it is back in its housing it might work how do they buy gear oil in these country's it's ninty dollars a gallon real gallon not yank gallon
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 didn't see where they had the earth lead hooked but it wasn't directly to the bearing being welded. Meaning the energy you see melting metal was also travelling through the bearings in the lathe. I'm surprised it still spins. Bearings hate having even small currents run through them. Its a huge problem at places like power stations.
@@watsisbuttndo829 oh I see, I replace bearings on my woodworking machinery as regular maintenance. Bearings look tough yet are very precise elements. Thanks for the answer.
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.
