THE MAKING(English Version) (314)The Making of Steel Balls

[@SIMKINETICS]

As a retired mechanical engineer, I've learned a helluva lot about all kinds of bearings. The first thing I learned was that there's much to learn about them! Until I watched some KZbin videos on their manufacture *after* retiring, I often wondered how they were made. This video is the best I've seen! Note that this video features a bicycle hub for example. I've invented & prototyped three different hub-based Continuously Variable Transmissions for bikes, each of which uses bearings in novel ways to achieve the continuously variable feature. We so often take for granted the importance of bearings until we imagine our technological world without them.

This type of awareness is needed in pre engineering studies to create the zeal in young minds.👌🙏

[@carlodave9]

Being able to create those little balls altered civilization more than we can fathom. But it all leads back to the invention and evolution of the lathe; which has been transformed by what it created, which transformed what it could create, and so on… It is interesting to see how important lathe technology is in this video. It’s all over the place-not just in what gets manufactured, but also in the creation of what does the manufacturing. Fantastic video!

[@Mike_Hughes]

@@carlodave9 Good point!

[@p.macdermott2490]

I never thought I would spend 14 minutes watching how steel balls were made, but I'm glad I did. This is an amazing insight into the manufacturing process. The videography is superb. When I saw the subtitle " flashing",. I expected to see a guy in a dirty mac appear. Hats off to to the guys who invented the machines to do, these precise tasks. It is worth noting, however, that it still takes a human to but the balls in a box.. Well done on this very informative video.

[@gregparrott]

You'll notice in the video here that after lapping, the balls are air-dropped on to one another. I was told that Timken does NOT air drop their balls after lapping because the impact between the very hard surfaces damages them, causing microscopic dents. Consequently, Timken drops them into an oil bath so the impact with other balls is kept to a minimum.

[@amplituhedron5582]

Never heard of that company, googled it and the first thing it appears is a picture of the ceo, on their own website. I'll trust japanese bearings.

[@gregparrott]

@@amplituhedron5582 I've not heard of 'Daio Steel Ball Mfg' either. They may make ball bearing assemblies for niche markets with lower volumes. It is VERY unlikely they make balls for a major Japanese bearing manufacturer, like NSK or NTN. Any of, say, the top 10 manufacturers are going to have extremely good quality. What would be interesting to see is how the process differs for the even more demanding ceraic ball bearings. They're stronger, longer lasting, ore precise, with less rolling friction, and are corrosion resistant.

[@HighGear7445]

I was involved in making tooling for ball bearings years ago. One of thousands of jobs our little header die shop did. The dies with the half spheres have carbide inserts that are pressed under high pressure in the die block. As these inserts wear they can be recut and ground to be used over again. The working surfaces are lapped and ground to a mirror like finish. The grinder used 2 different grits of wheels to get to the finish required on just the face of the die. I used 12" diamond wheels on the surface grinder. It was quite an involved process to make the tooling and the more precise the tooling the less work was needed for the secondary processes (grinding and lapping). It would be fun to see the processes used to make the tooling ....just another job at our shop but most have no idea what it takes to do it.

No doubt. You can't fight a World War without balls of steel. Any machine shop was a big target in WWII but bearings are specialized. One shop can't just take over where another left off. Any machine shop can make an axle shaft etc with standard machine tools but highly specialized factories can't just shift their work to another shop. That made bearing factories and other highly specialized manufacturing plants particularly important targets.

I used to work for an environmental company and serviced a company that made ball bearings in Norfolk, Connecticut. They made all types of ball bearings from steel,brass and gold. Was amazing to watch how they were made and the different types. They were made a lot different that the newer machines make them. Nice video thou. Thanks

[@aerialexplorer772]

@@ganymede3141 Indeed, how did they make the ball bearings used by the machines that make the ball bearings?

[@ganymede3141]

@@aerialexplorer772 Exactly. How were the very first ball bearings made? It must have been a very expensive, manual and slow process to get good enough precision until machines could be built with higher and higher tolerances and process improvements to yield better and better parts with each generation of machinery.

Side note from a metallurgist here (educational comment): Quenching in oil rather than water achieves a slower cooling rate. That creates the desired microstructure for this application. Quenching in water simply produces a harder and perhaps brittle structure that isn't as useful here. The annealing process, the reheat to 170C, does not, strictly speaking 'align the molecules'. It is used simply to get the desired microstructure, one that has the hardness and toughness appropriate for this role. The initial, relatively rapid quench of these higher-carbon steels produce hard structures called martensite within a softer ferrite matrix. The annealing process transforms the martensite to the degree prescribed for this application. Molecules are being rearranged but not specifically to align them. Martensite forms as a spiky structure in three dimensions upon quenching. Annealing 'blunts the tips' to the degree it needs to produce the strength and toughness require. Not a criticism here!! Good video. I am learning from it.

Beautifully made video to show the ingenuity of science applied in technology. Anyone with ability to use their brain will be in awe.

I think it was 'special'

[@XD-inator]

Well steel is considered 440 material. There obviously chrome, gold, REX 40, silver and so on

[@FlamingToaster]

yeah, i love how nonsensical it is. "Steel balls are made from wire rod called steel made of feroalloy containing carbon." There are several layers of nonsence and bullshit in there while still being somewhat correct and sounding ultra fancy. Insane.

I sold bearing for 40 years but never saw how they were made. This is very interesting....

[@rmikemcd]

Train axles do not contain ball bearings. They use tapered roller bearings.

[@sailormandave1]

I always thought they were plain sleeve bearings because of the weight they have to bear. There is a stuffing box on the outside (square hatch cover) over the axle and i always saw the maintenance people put grease into that.

[@dougborrett3566]

That was how they used to do it before they changed to roller bearings

[@sailormandave1]

Well learn something new every day. I guess bearing materials have progressed since i was young.

[@DoomFinger511]

Interesting, I just looked up what tapered bearings are. I didn't know there were different types of bearings.

[@odatmatt]

That is where Timkin bearings got their start, making bearings for trains. Before that they were ball bearings, they wore out fast and were limited to the load they would carry.

[@StrangerHappened]

*I LOVE the adorable and funny sounds* Japanese TV shows add to even serious videos. The reason why those sounds are so popular there is because Japan is the country of computer games, many of which were invented there in the first place along with the corresponding cute sounds.

[@taotedance]

They are properly known as bearing balls. My dad worked as and engineer at Fafnir Bearing for most of his working life. High precision balls are round to within several millionths of an inch. They are sorted into matched sets before assembly with the inner and outer rings and possibly a ball retainer and seals.

[@lemontier]

Very good video. Like most I have always wondered how ball bearings were made. Now I wonder how long the machines that make them last at the speed that they operate. Just the process of filtering the metal waste from the oil and processing it for scrap would be monumental. Maintenance on the whole operation has got to be enormous. It is hard to believe how inexpensive ball bearings are considering all that is involved. Thanks for the education!

[@endurofan9854]

agree, some bearings are even very cheap

[@BixbyConsequence]

1:48 So the author thinks we'll all be familiar with "ferroalloy" but they're going to blow our minds with the word "steel"! Lol.

[@Arterexius]

I noticed that too. Luckily I can answer it for anyone wondering: A ferrous metal is any metal which possess magnetic properties, such as Iron and Steel. A ferroalloy is an alloy of metals where at least one contains magnetic properties. And example of a non-ferrous metal is Aluminum. Scrapyards usually use magnets to figure out if the metal being sold to them is of ferrous origin or is a non-ferrous metal as pure aluminum and pure iron is practically impossible to distinguish from each other without using a magnet. To anyone needing to know why rust makes iron or steel impure, know that rust is nothing else but oxidized iron or steel aka, meaning the surface of the metal has come into contact with oxygen. Some metals create a protecting layer when they oxidize. This is the case of Aluminum (the traditional grey aluminum surface isn't paint. It's oxidized aluminum) and Chromium, with the latter being used in the fabrication of stainless steel as it is the oxidization of Chromium which creates a protecting layer over the steel, causing it to be resistant to rust as the steel never gets into contact with Oxygen, thanks to the Oxidized Chromium layer. Also, if anyone wants to look up an OP metal alloy, take a look at the properties of Alubrass

[@koomky]
