Process for mass producing bearings. A bearing factory boasting Japan's number one production volume 

Yes. I was wondering about the forging of the inner and outer rings...

I could only watch it halfway because this movie was pointless. This is not what I'm used to from this channel. It was pretty much just about different ways to transfer of the parts. The 1-minute summary at the beginning of the movies just wastes our time.

Totally agree@@lenardlazar8622

There could be a reasonable explanation for this, like it wasn't viewable (hidden inside a machine) or it was not allowed to be filmed (company secret).

Yes i'm sure there was a reason and I know i shouldn't complain about free content and the other videos on the channel are mostly good but i really enjoy the sections they missed.@@imakeoscillations7026

In all other similar videos, no one EVER asked "hey, can we add some music to your videos?" but instead, greatly appreciate when there's NO MUSIC at all. I don't understand why content creators don't get this message. A soundtrack in a movie is there to provoke a certain emotion and we do not need to attach any emotion to most YT videos.

agreed, i want to hear the machines, not the crappy music

Japan and Germany best

It's not so much a video about how bearings are made, as it is a video about how the pieces that make up bearings move from machine to machine in the production line. Don't really see ANY of the actual making here...

"trade secret" and "intellectual property" ;)

Since it is very hard to create ball bearings that are high quality, you'll likely never get to know the exact methods and materials used, unless you are an engineer designing the process. Especially the polishing phase, which, in high quality bearings (like from Koyo featured in this video or SKF or INA/FAG), will bring down the tolerance to about 0.001mm or less. The raw balls themselves, before heat treatment and polishing, can and often are manufactured by a steel mill. To show how producing a small steel ball can be quite an endeavour, even if you know the individual components, but not the correct process, consider this: China need to invest millions upon millions and several years of research, testing and development, to produce high enough quality steel balls for roller ball pens. Their initial tries leaked and/or wrote quite badly.

@@Schnittertm1 there are quite a few videos of making the balls in ball bearings on youtube

Могли бы хотя бы роторную линию показать по изготовлению колец

You use long steel tube and cut into pieces. Then press the piece to form a ball. Cold forging. This process takes few milliseconds. I think NTN video shows that. Then polish the balls to make them as round as possible. Then heat treat. I am a tech. If bearing is not made in Japan, I don’t even hesitate to put it into the bin. Japanese bearing just lasts forever.

@@tnak004 German/Swiss bearings are of equal quality.

The company was scared for it's secrets and didn't want to show anything really, that's why this video was a waste of time.

secret? youtube won't tell you everything about the world..

I use Koyo bearing on my Subaru race car. The differential carrier bearing. The machining, the dimensions, and quality are just perfect. If you change differential, you need to check backlash and contact patch. Koyo bearing. One shot!!!! All within Subaru specification. You are talking about backlash of 0.1mm to 0.2mm. Bearing machining plays a vital role to fit absolutely perfect. Koyo bearing can do that.

😂😂😂😂

Really? Why? Germany Stihl Mercedes BMW Audi not better?

@@luxbeci2 because they use Japanese bearings. I am a tech. Audi, BMW, and VW are just JUNK. I hate these cars more than anything. Always come back with same problem. I really want to send them to scrap metal right after they roll out from the factory. I always tell people not to buy them because they just waste our precious iron and other metals. Well guess what, who makes Porsche’s ABS unit? Denso does. Who makes their gearbox? Aisin does. You see……. Core parts are made in Japan. What do they have in them? Japanese bearings. My BF5 Legacy GT Japanese wheel bearings. 350000km. Still no noise. See….but there is only one thing Audi VW and BWM do best. Inventing new bolt heads which makes techs annoying. The reason why Germany lost their sprit is forgetting quality and warranty is their limit and learned to fake people with interior quality. But Lexus does both better and way more reliable than Germans. The reason why Japanese bearings are the best? Japanese used iron to make swords. They have great know how to forge and quench iron. That’s why.

日本神話。過去の遺物。

@@luxbeci2I don't know how google translated it, but he just said "they're top quality". Doesn't mean Germans' are lower. And I think Germans' are equally good and for specially designed ones they are better.

Так в том то и дело. Ну, процесс шлифовки колец там ничего интересного, а вот шлифовка и контроль шариков это да!

Warum sollten sie Produktionsgeheimnisse preis geben?

@@andre_s. Warum dann ein so „lautes“ Inhaltsverzeichnis erstellen? Vom Namen her erwartet man das eine, aber in Wirklichkeit sieht man etwas anderes.

@@Horse55 Там ещё меньше интересного... громко и грязно 😭

内容が薄かったですよね、町工場レベルの場面しかない印象です。

しょうがないでしょう。赤の他人のRU-vid動画の為にリスクかける理由ないですし
