One day I'll get through this entire segment without giggling; that day is not today.
@@bunkerjoe2226 no, and now I'm laughing thinking about it.
This clip from another how it’s made will help

I didn't even think of that until you mentioned. Grow up
@@colecoleman1499 ...no.
That's amazing how it checks the weight at the end so accurately on the conveyor belt. Actually, every part of this is amazing.
One of my favorite parts made in machinery. Bearings are overlooked but one of the coolest parts on earth.
We couldn't agree more!
@@NTNBearings - Man it's so cool you're still responding to comments! Hope your day is going well.
@@TheWiseDrunkard Thanks. Same to you!
"The ball cage" always gets me
Next episode: How were made the machines from "How it's made"
best episode for engineers
Ever wonder how ball bearings are produced? NTN was featured in Discovery Channel's "How It's Made" series. Watch the process below!
NTN Bearing Corporation of America
Bearings ntn orginal made in?....
but surely the machine itself will have many bearings within it due to the high amount of moving parts. which leads to the age old question...
what came first, the machine, or the bearing?
Great question! It is speculated that rudimentary roller bearings were used as far back as ancient Egypt. We have evidence of roller bearings being used by Romans over 2,000 years ago. Leonardo da Vinci drew ball bearings around 1500. The first practical caged-roller bearing was invented in the 1740s by horologist John Harrison, and the first patent on ball bearings was awarded to Philip Vaughan in 1794. Because of this historic evidence, we can be confident that the bearings came first!
as a machinist i always dreamed of having a job in a precision place like a bearing factory
Lmk if you are still interested. I work in anbesring factory
How its made is very useful episodes for engineers
this is so cool ,now i feel bad for complaining about the cost of a bearing set .
If the guys from NTN are reading any of this, how do you determine a counterfeit NTN bearing?
Hi Paul, That is a good question. The best way to ensure you aren’t purchasing counterfeit NTN bearings is to purchase from an authorized NTN distributor. Our NTN websites offer ways to search for our authorized distributors. We aggressively pursue the import/export/sale of counterfeit bearings around the world, but counterfeit bearings can often be purchased from legitimate looking websites that turn out to be fake. NTN also offers a bearing authentication app that can be used to scan the label on an NTN bearing package to ensure it is not counterfeit: ntnamericas.com/technical-resources/bearing-authentication/
There are additional, industry-wide resources available here: www.stopfakebearings.com/
@@NTNBearings Can you explain the package labeling thing for people to understand? Are all bearings supposed to arrive with some such QR code on the packaging?
I recently bought a bunch of NSK bearings off of Amazon. NSK also says they do the secure QR code thing.
www.amazon.com/gp/product/B07TDDDV8T/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
There was no QR code on the packaging. The inner race had "Poland" engraved on the inner race and "China" molded into the grease seal. I suspect counterfeit.
What about automotive wheel bearings from the auto parts stores? Should I expect to see a QR code with them as well?
cool ball bearing factory bro
Are these still made in the USA
NTN has 76 production facilities in many different countries around the world, including 11 in the USA. This particular segment was filmed at the NTN production facility in Mississauga, Ontario, Canada.
That's a lot of balls...
Balls of steel
Lunchpacked180 Go to bed, mom!
nice video
New drinking game- every time he says "ball" or "raceway"
amazing
there i hav NTN bearing UC 208-108.And this bearing suits a shaft dia of 1.5 inch.What this 208 and 108 denotes ?Also there 208D1 bearings, it has the diameter for 40mm shafts.What is D1 here ?
I worked there for 20 years and was present when this was made. Not a lotta fun trust me.
That's pretty cool, what was the process like?
+Crazy Hobo Like this video.
I'll bet you never got tired of making up new "balls" jokes.
No steel factories where ever fun, but that's life, used to work in a welded wire mesh panels, what a mess :(.
How do they get the balls inside the races. Something has to give. I see some have a slot to install the balls, but something has to stretch, give or bend to pop the balls between the races.
Its unbelievable what humans are capable of, we'd still be hunter gatherers living in caves or huts if people were all like me lol. Amazing technology!
you made someone laugh after nine years mister! laughed my shit out. 😂
@@hankatmaggies8819 👍
The cage is a critically important component. If the cage corrodes and breaks, the balls all move to one side and the bearing falls apart under load. The cage will probably be the first to fail in a corroded bearing.
+Dale Mahalko
Or the bearing climb on top of each other and burst the casing.
Its a bearing eat bearing world
Hello hambini fans and welcome
Cool.
ntn sealed bearing are great and long lasting.
I love bearings i will never forget them
WOOOW
How many times did they say "balls"?
And this video from 6 (!) years ago is just one indication that manufacturing will never again be the job creator it once was. If you want to be in the industry, learn how to design, build or maintain these devices!
I spent 28 years as a maintenance tech on machines exactly like the ones in the video.
And this is how fidget spinner is born all about bearings
minus many point for not showing the process of die cut shape to final ball. in fact you lied with that title
Trivia: All ball bearings made are metric...even in countries where the Imperial system is used.
Yep. Most of ours were made to less than 3 micron tolerances. For rough calculations, we always figured a micron as a forty millionth of an inch.
How many times does he say balls?
thats a good fidget spinner right there
FOR MORE INFO ON NTN WE ARE DISTRIBUTORS
A lot of things are used with these, far more then people even relise, even skateboard and bmx bikes use them nowadays.
bro skating and bmx have used bearings since day 1.
Not sealed bearings.
cool i just ordered one NTN bearing, hope its good quality !
240p, good to see you again!
I use ntn in my snowmobiles
How does one bearing cost so little!!!
anyone know what grease is used in them?
NTN uses a wide variety of grease in our bearings. The type of grease used is dependent on the type of bearing, its intended use, and the conditions it will be subjected to, among other factors.
It's crazy how these are used in skateboards if I ever need bears just bust my printer open
just the most important thing here is to see that how so precise and tight between the periphery of the bearing balls are obtained. It would be most interesting to know, but do not see it here.
How does balls get nside between race ways?
It isn't an inside piece and outside piece. It is two sides with the balls in between.
they did a shit job explaining that
Scotty Jones Yeah I don't understand that part either. To be honest that's the only part I came to watch the video lol, and I still don't know the answer.
Scotty Jones they have a ball divider
Oh ya! Its all clear now! Ball de vid ers ay?
The rejected ones are the cheap ones you buy on eBay.
I worked for a ball bearing mfg and our rejects were generally sprinkled with salt to prevent them from ever being used with our name on them.
That's is it...!!
Grease must fill high quality which bear high temperature
Yes, the bearing grease is very important and is often overlooked. The primary role of lubrication is to reduce friction between bearing components and help dissipate heat. Lubrication also serves as a vital barrier of protection against contaminants. Lubricants also help bearings endure different loads and act as a stabilizing agent for bearing structures. Lubrication is one of the most important factors impacting the operation and longevity of bearings, which is why it is important to inspect and monitor bearing function on a regular basis.
Bouta use these bearings for my 52 mm wheels wish me luck😭
2 uses in and they already sound partially rusted and dirty 🥴
Hes got ........ Balls of steel *badumtss*
High Quality NTN bearings as a company from Japan.
I thought this was going to be about how the actual balls are made. That would have been more interesting.
there is also an episode about that here on youtube
Actually the making and polishing (called lapping) of the balls is a long, slow, boring process that takes hours. The company I worked for had cycle times on the assembly machines of 2.5 seconds per bearing...much more entertaining to watch.
2:47
please God someone remove the "go through a furnace to" part of that sentence and make the after product a standalone video *XD*
*the balls harden*
No closely guarded secrets in here?
Those look like Bones Reds.
What kin d of steel are bearings made off.
Normally you use stainless steel or 100Cr6 (Bearing steel)
I bet ya that Machine that making the ball bearings has ball bearings it self
ball jokes a plenty
now i see why this was on my recommended..because i watch videos with fidget spinners
They left out the biggest and only question there is to ball bearings-How do they get the balls in the two valleys of the raceways????
Kayenne9 yeah. ive been wondering about that about 2months now
No they didn't, the inner race is pushed to one side, all the balls are loaded up in the big gap that is now formed on the other side between the inner and outer race. The balls are then separated which locates the inner race into its central position at the same time. The cage holds the balls in their correct location, without the cage all the balls would bunch up at one side and the inner race would then fall out!
@@sidecarbod1441 To get the balls to fit, the outer "A" ring is squeezed slightly, then released. From that point on, the balls will stay in place. In tight tolerance bearings, the balls will not fit into the gap without squeezing the "A" ring.
@@ytubepuppy I have disassembled a ball bearing in the past, without the cage in place it is possible to push all the balls to one side so that they are touching each other, once this is done there is enough room opposite the balls to remove the inner race. So it is clear that the reverse of this process is how the complete ball bearing is made. Try it, get hold of a bearing and pull out the cage, the rest of the bearing will just fall to pieces!
EDIT..At 3:18 you can see the balls all at one side of the bearing, the narrator then says " A ball divider positions the balls evenly around the raceways" There is no squeezing of a "A" ring!
@@sidecarbod1441 Yes, there is a station on the assembly process right after the "ball insertion" stage called the "ball gathering" stage where a stopper comes up to hold the balls in place, the inner ring is spun, causing all the balls to gather in one spot, then the "ball separator" fingers come up between the balls, followed by the upper cage insertion to stabilize the balls then the lower cage with the rivets, then the rivet press.
There is also a salvage process in which the rivets are pressed back out, the cages removes, the rings separated, and the balls scrapped before the rings are reassembles.

Ball divider
+TedOfNod ugghhhh...!
For me a much less irritating 'voice-over' than in the UK.
All that "high tech hoopla" nowadays ...
OK, I'm totally confused.
i still dont get how they fit the balls in the raceway so easily
Yea, I too watched the whole video, solely to try to learn that. And they did not say how.
Luckily someone here in the comments hinted on what sounds to me like the right answer, which is that:
- the balls all packed together against each other, only fill, roughly half the circumference of the rings races.
- so, while feeding in the balls, the inner ring is out of center, and touching the outer ring on one side.
- then just space out the balls, and the rings self center and cannot separate anymore.
I looked this up and I still don't know!
the balls go in an oven to harden then they get a solvent baths...next comes the ball cage
*B A L L*
So many opportunities for "that's what she said" jokes, but I'm going to leave that to the other commenters
and the SKF fix them and sale for the double price...which is not bad because last 3 times longer than NTN.
high tech hoopla
And now fidget spinners
mine
if he says balls one more time

That machine needs a lot of balls to work there.
Everyone going on about their steel balls....grow up, people.
Good job he wasn't talking about the premature combustion as the piston thrust deep into the sensual cavity of the carburettor....
Grow up..
That's neither how an engine works nor how to spell carburetor.
Thank you for saying it so that I didn't have to.
I'm no engineer but my understanding of the four stroke intercourse system is as the piston thrust deep into the aroused carburetor an orgasmic combustion occurs and the emission is swallowed up by a thirsty and unabashed outlet value.
And that in certain cases this combustion can occur prematurely depending on the friction between the piston rings and the lack of lubrication on the inner wall of the carburetor...
Unfortunately, there are some people who are childish enough to view this in a sexual manner...
Sadik Meah The piston thrusts deep into the block hole, was my point.

Gotcha!
BALLS
I lost it at 4:50
more pixels please
dont you just hate it when you get all these how they made it and how to do it videos and the one speaking like this guy can not speak english properly and its not understandable what on earth the person is saying
The ones the machine puts out are the ones you buy when ordering from Alibaba... just saying :P

Did anyone else get this recommend after watching fidget spinner vids?
like if you are here because of fidget spinners
rough balls? 02:32
Did anybody ran out of stuff to watch?
Hehe. balls of steel...
