HYDRAULIC PRESS VS BALL BEARINGS! Which will EXPLODE first?

In this hydraulic press test we find out which is the STRONGEST ball bearing! Cheap Chinese or European? For the experiment we use our 100 ton hydraulic press to crush the bearings and super accurate force sensor to measure the breaking point. Our slow motion camera captures the bearings exploding at 1000 frames per second!
Let us know in the comments what Hydraulic Press Videos you want to see next? Satisfying crushing compilation? Dangerous Hydraulic Press Videos? How Strong Are...?

[@kenschultz3836]

A better comparison would be longevity and durance rather than crush. bearings don't wear out in a crush setting. Spin them without grease at 3450 rpms and see how long they last is a better comparison.

[@henricinelli4339]

I think the point of the exercise is to show CHINESE STUFF IS CRAP, !!!! FFS.

[@dylan.indonusa]

SKF bearing is made in china as well

[@robertogarcia6787]

lo chino no sirve .

[@HydraulicPressGuy]

Totally agree but how many people would watch that video? This is just a crush test for entertainment 📺

[@ronaldobuchoski3490]

Sem sentido não disse nada

[@John-vk1ij]

Testing a bearing this way is like, testing how much heat a computer can generate to work as a space heater. And btw, this is a $22 to $0.4 comparison so a result 4394Kg vs 3104Kg is very very reasonable.

[@QUIGS102]

Yes

[@CzechitOutGraphics]

But it looked cool

[@MrPegasusfeather]

Agreed, this is pointless test

[@garyt.8745]

Is it really a pointless test? So you put one of these in each hub of your car/van (which weighs from 1450-2000kg). Then you put 2 to 4 adult passengers in there (160-400kg), and load the load space up with another, say 500kg. That's a total of 2900kg at rest (distributed between the 4 wheels, so let's divide equally by 4). Then drive that vehicle, at just 60mph (100kmh), over a 5cm deep pothole, or a 5cm bump. That's about 39,000N of force, per wheel, or 3.9 tons. Sure I'm not taking into account the damping of the suspension, tyre pressure, unsprung/sprung weight, etc. but even so that is _above_ the tested capability of the Chinese bearing (and _undoubtedly well below_ its _claimed_ load bearing). So yeah....I'll certainly go with the SKF bearings in my vehicle, with my two kids on board. No doubt whatsoever.

[@John-vk1ij]

@@garyt.8745 thanks for doing all the math. However, this type of bearing is never meant to be used that way. The force applied on the bearing is between the inner ring and the otter ring, from the axial to the chassis. You have ever right to choose whatever tool you want. It’s your money anyway.

[@streetbeaglekz1923]

2. Points. 1. these types of bearings aren't meant to take shock or point loads. 2. What was the static rating for both bearings? If the datasheet values exceed the test results, then that's fine. nothing wrong with either. Just more margin on the SKF Bearing

[@vikassm]

One sample .. unscientific test... useless load .. good for entertainment!

[@AngrySoybean-j]

@@HydraulicPressGuy 👍 but some people don't get it😅

[@aus-reviews8462]

they hold up pretty well considering how much force it needed to break

[@ThereWasNoFreeName]

To me both held very well and way above actual workload.

[@sempertalis1230]

Somehow I fail to understand this test. These ballbearings are not made to withstand these forces, they are bearings, so the right test would be to see how long it takes to wear them out.

[@HydraulicPressGuy]

This was just a crush test for entertainment 👍

[@Danji_Coppersmoke]

Love no filler video👍. Let be realistic... it is probably Chinese bearing vs Chinese bearing with SKF label on it. I assume the label sticker is pretty strong.. .🤣🤣🤣

[@Motorbronx]

Bearings are rated much higher when they rotate compared to when they don't, or else you could make a thicker outer casing for the Chinese one and pass the test. These things need to be tested when they spin.

[@HydraulicPressGuy]

Absolutely, this is a just crush test for entertainment 👍

[@GilsonJr.Whitout.Numbers]

Honestly, I expected a bigger difference. But there are different types of stress in bearings. When I find them here in Brazil, I use Timken.

[@alec-s]

Bearing are not meant to work that way, what they bear is a radial force applied compressing internal ring on the external one, properly mounted in their support or seats

[@HydraulicPressGuy]

This was just a crush test for entertainment 👍

[@won4151]

Lol I'm more than 50% sure that SKF bearing is also made in China. 😅😅

[@andrew24871]

is made in Italy. I bought one

[@HydraulicPressGuy]

This one was made in 🇮🇹

[@Gemma.love2023]

Really enjoying these types of videos, love the sound and slow mo!!

[@HydraulicPressGuy]

Thank you Gemma 🤜🤛

[@randywatkins2359]

After the explosion, testing an individual bearing vs the other would be interesting.

[@HydraulicPressGuy]

That was the plan but they were so hard they sunk into the press head! When the press heads have been through a hardening process we will try again 🤞

[@REDMAN298]

I used to inspect and repair trucks. The chinese bearings failed much sooner than we were accustomed to.

[@rlegate7357]

I was a mechanic for years and taught technology in high school. All manufacturers know how to make great stuff, crap, or anywhere in between. It's a market driven choice. Jobber bearing cheap. Lexus bearing top quality. Chrysler bearing, make it last 150k km. For the most part, the consumers are too busy to educate themselves enough to really know. And yes this is a silly test. A Rockwell hardness test would be much more appropriate.

[@HydraulicPressGuy]

Absolutely, this is a just crush test for entertainment 👍

[@AlphatecEngineering]

Wonderful video, we love this channel. But it would be good to put in the description that is not the way bearings are tested. Thanks guys for your cool videos!

[@HydraulicPressGuy]

Cheers guys! This is a crush test for entertainment. I can’t edit the description now as it might effect the meta data and stop the views but I’m sure anyone who watches this for anything more than entertainment will know this isn’t a relevant to for bearing longevity 👍

[@ytfanlingeric]

This type of comparison is meaningful only if the design specs are stated.

[@dimmer4955]

A very smart test from a technical point of view. Try testing your Intel CPU with a Chinese CPU next time using this method. Or Swiss watches versus Chinese ones.

[@matin4415]

[@HydraulicPressGuy]

Thanks Martin 👍

[@davidlafferty8414]

I worked for SKF for 5 years and never heard or saw them test a bearing like this.

[@user-xe8jd5we9l]

Спасибо! Было интересно ,особенно в замедленной съёмке.

[@HydraulicPressGuy]

Glad you enjoyed it 👌

[@balboa9439]

Can you put the cover on the chinese one and test it again? I wonder if that "weak" part actually helps with the stresses that occur in the metal parts when they are being compressed.

[@HydraulicPressGuy]

The Chinese one didn’t have a cover, but next time I’ll get one that does have one for a more fair test. BIG ONES next time 👍

[@balboa9439]

Great! I subbed to not miss that :) If you still have those bearings then just swap the cover (not sure if it will fit but it should)@@HydraulicPressGuy

[@bjorn2290]

SKF swedish made

[@josephvella6669]

That the Chinese bearing broke sooner means that it was harder which probably means that it wears less. In any case, bearings are meant to last longer not withstand more pressure.

[@HydraulicPressGuy]

This is a crush test for entertainment 👍

[@honingholes7026]

I know someone who used to bear the pressure on the webs of the press cradle and he damaged the cradle.

[@andrewwilson6085]

A better test would be rotation with a load on a shaft, which is what they are intended for. Then check for wear after a time

[@HydraulicPressGuy]

Yes, to test which is the better bearing that would be a better test. But people want to see crushing and explosions 💥

What about the price? I do not deny the quality of SKF, but for the same model, users do not necessarily need to pursue extreme indicators. The increase in costs caused by price differences is a priority for users. Just like Carl Zeiss or Canon cameras and lenses , which one is better, but which one will you choose ?

Very true, SKF was 4 times the price! 👍

The reason why Chinese bearings have a shorter lifespan than SKF and NTN bearings is due to the difference in the strength of their shells. Bearings used in MTB wheels that are made in China have a lifespan of about one year. NTN lasts more than 2 years.

It doesn't matter the "chinese" or else bearing. They are made in China, both of them. It is a matter of quality. Our importers choose the cheaper stuff in order to enlarge their profit. You can buy 1st. line products in China if you settle paying more for them. Then you will have quality comparable to any other manufacturer in Japan, the USA, Germany or whatever. Simple as that.
