You should update the software on your Chronos camera! The version you're running is about 3 years old and we have made a ton of improvements since then. You'll be pleasantly surprised. Some more light will make a world of difference as well. Love what you guys are doing. Please spin more things!
OH SHIT ITS THE REAL Chronos Cameras
Chronos cameras Y’all are on my Christmas wish list 🤣 what do you suggest for a “new tuber “?
The shots really are dim. Not enough time to get a decent exposure inside with such a high frame rate, I guess.
I hope they see this!!

Turn into an adult and these are my saturday morning cartoons.
Today is Saturday?!?!? Oh God oh no
@@twosquids I was just guessing. At my age, you never can keep up.
I'm in NZ. These vids drop at 2am Sunday. Get home from the pub and this is what I'm doing haha
Thank god we are adults...
Sunday for me... Hahahaha
You guys are just getting started, size wise. Dad worked at a steel mill and once when they had to replace the bearings in a mill he brought home the box one came in. It was big enough to make a nice treehouse for us kids.
Yea when you get above automotive wheel bearing sizes the price per bearing goes waaay up there.. saw a bearing that was about 18” od with a price tag of $13k.. das a spensive spinny bit..
@@Z-Ack I've got a 20" roller bearing lying around I got from work, it's a little worn out, it was pulled out and replaced after a gigantic gearbox rebuild, but the thing weighs like 90 pounds, I can't imagine how much that thing cost new. It's a whole different game price-wise when you get into the big stuff. I wanted it as a display item in my man cave, (for whenever I get a man cave lol), my boss told me to get rid of it so I did😂. It's also got like 25 pounds of brass in it, it's going to look nice once I clean and polish it all up.
The big bearing was supposed to be packed with grease and it was missing a seal. It's meant for low speeds as well
Pretty much any bearing that has the bearings exposed should be packed with grease. The fact that the bearing that didn’t spin freely, didn’t spin, is a good indicator that it can be used at high speed because as the grease heats up it will spin more freely.
@@SCWW or it was a bearing from a gearbox that uses oil instead of grease
Not necessarily on the speed thing. 1800 rpm is not an uncommon industrial motor speed. I've seen a few motors in the shop that took bearings that large that run at that speed although they tend to start runing slower around that size. You could potentially have a 5.5inch output shaft on a motor using one that size. Your right about the seal though. It does not take much contamination to jam a bearing. They also dont like runing loaded or at high speed with no lube. @Jesper Jensen, commonly in motors the bearings are either fully sealed with a measured amount of grease inside from the factory or they are open and theres a cap behind to bearing to hold grease in. This allows more grease to be added over time as the old wears out. Open bearings in a greaseable motor generally last longer before needing to be replaced if the millwrights actually follow the manufacturers recommended greasing schedule. Sealed bearings are effectively a wear item. Clocks ticking once they are put into service and you can make a reasonable guess as to how many hours they will last depending on the service speed and HP of the motor.
If he showed the part number we could see the speed it is rated for. The shaft sizes where also incorrect it should have been so tight where you cant pull it off with your hand, only a gear puller or a deadblow hammer. Rookie mistake.
@@fang4853 These bearings do not really have a speed limit. It sure has a limit but these limits are as good as unreachable. Bearings can do tens of thousands of rpms
Those rods are definitely above average. Arguably could even be considered large.
Crazy, that's exactly what they said.
My harley has larger needle bearings on the crankshaft than those in the video
The bearing looked like it had a great personality too
I bet they're really nice, too.
That bearing has been told “Yours is fine the big ones hurt” 😫😭
Bring back Dan and Mitchell !!!
no
What happened the lads. Miss them also
Starting the bearing spinning with your hand was friggin terrifying
Right???!!!
I run a waterjet and can vouch for that, that’s risky as hell
Especially after seeing what it did to the gel hand. Jesus.
Yeah...easily could have lost his fingers right there. WTF was he thinking? Is he a professional operator or just a KZhead dude with access to this machine?
@@oisiaa yes
I would also like to add that I think those needle bearings are PLENTY large
Maybe you should have packed the big bearing with some waterproof grease, might have kept the abrasive out for longer.
Do a tank cleaning video! has this not been cleaned since you got it!?
They have a system now that does it automatically, basically pumps it out into a devise that collects the garnet, and recycles the water back into the tank
Rods = needle bearing. Typically used in a location were a shaft isn't supposed to have much movement side to side and the bearing serves to center the shaft in a tube. Like axle shaft bearings.
Needle bearing? I think you meant average bearing. Thick bearing even...
@@Bubu567 Needle bearings are a type of bearing. Not size. Look up R59047

Always look forward to Saturday mornings to see these vids
How do these guys not have 10 mil subs yet? They make consistent content and have been at it for ever! I would think this would draw a very broad audience
Because they aren't the original people who ran the channel, they've suffered a huge viewer loss because of this
@@Scarlet_Soul it didn’t even register on me. I haven’t seen it for a while. Now it makes sense. Thank you
@@Scarlet_Soul what happen too the original people?
@@thejwilliams333 They have a new channel where they work on cars

Man I was here to this channel when you were 10k subs, road to a million here we goooo
I don't know why things spinning super fast is so intriguing
Would it be possible to pre-grind some ridges or texture on the the berrings to give the water something to push against so it doesn't get stuck on the abrasives?
It would be like a tiny water wheel, that would definitely help torque hugely
I use to be the go-to repair guy for a piece of equipment rated to 18,000 rpm (We never went over 10,000). It had four of those large cage bearings like you have. There was active oil misting of the bearings. If the mister was running too much oil (more than a single drop per minute turned to mist and split 4 ways) the machine would start bogging down. The areas of the machine where the bearings were would get hot. Very hot. During normal operation those areas would become warm to the touch but not hot. When the oil ran heavy the machine would get hot enough to smell, and smoke would rise as it burned off any oil on the clamshell housing. I replaced the older oiler with a new one, and mounted it in a location that was not influenced by the machines vibration. Never had that problem again. Over 15 years. Set it and forget it beyond refilling the reservoir every month. And the point is? Cage bearings are made to run clean except for a microscopic film of light oil. At least when they're being run fast. Under perfect conditions those large bearings you had would easily run 10k or more.
Niiice, glad to see the revisit with bearings! Good stuff guys!
"Stop using abrasive!!" Bro, if they were using abrasive there wouldn't even BE a wheel.
the sound of the wheel being spun by the air compressor at 1:44 really reminded me of a 2JZ or an RB28 lol
you guys should make shorts, this type of content is perfect to recut into shorts alongside the main vids :)
Where did Dan and Mitchell go?
you should get the slo mo guys in with a 4k phantom camera
It's time to clean out the water jet
Sticking your hand under that nozzle with someone ready to turn it on was the stupidest thing you can do.
I don't know who these people are, but having seen this channel years ago, I can safely assume the entire original gang fell into the waterjet and were neatly bisected.
Lol so funny! I would love to see you clean the tank and see what is in the water, must be so much random stuff from your videos
still no lick test 😡😡😡😡 bring the OG guys back
What happend to them two?
@@KevinK88 idk that what I was wondering they were funnier
While working in a Salmon Cannery in SE Alaska, I took one of the larger used machinery bearings (apprx 2in Wide x 8in Dia), cleaned it up and added a few drops of 30W oil and then hit the side of the ball bearings w/ some Shop Air while holding the internal Race w/ my hand. I'm guessing it hit around 10K RPM before I dropped it to the Warehouse Concrete floor. It sat there and just made sparks for a second or two and then accelerated the entire 80 yrds length of the Warehouse and went thru the metal siding on the other end of the building. There was a Semi Trailer parked in the loading pit next to wall that took a hit. Bearings are of such tight tolerances that any grit or dirt is gonna add a lot of rotational resistance if it doesn't stop rotation entirely. Ur little water jet experience w/ all the cutting slurry splashing up into the bearings was bound to be a bust. I think the plastic and lower tolerance bearings worked because of their "sloppy" build tolerances.
What happened to the original host these new guys are trying to hard and messing things up
"Usually you don't want things weighing 1000's of pounds spinning at 1000's of RPM" lol
We want Dave and Mitchell back
dude chill they are still on the channel let them have a break
Nothing wrong with these guys but dave and mitchell are what made me subscribe
Agreed
Do you know what happenned to them? Did they sell out the channel? Even the waterjet reddit is set to private and I can get no info on what happenned with them/channel
@@primozuadowondering the same
Would have helped the needle bearings if you used the correct shaft size.
3inch is a sealed bearing so it’s packed with grease that’s why it goes slower
Idk if anyone has commented this yet but any bearing that seems slow but is still smooth is because it has been greased as a bearing should be. Those sealed ones definitely have a grease inside which slows down the bearing with no load but is essential for loaded applications
Glad to see you guys getting back to the old, tried and true video style! Definitely a change in the content not having Danielle and Michelle, those guys were really enjoyable. This video with you new ladies is better than the older ones where you went off into the weeds trying to do content similar to every other KZhead channel. Keep up the good work, I really enjoy this channel.

Top tip, with ball races point your water/air jet at about 20 degrees to the ball cage not the external diameter, that size bearing your using should reach around 40k to 50k RPM (air is better and may even achieve higher revs before disintergrating) you will have to make improvements to your containment system!
The big bearing spins easy due to no grease. The sealed ones are packed. As the grease works out as the seals break down is why they free spin over time.
Finally, a worthy competitor for ball size
Ok maybe I have missed something from not watching in a while. What happened to the original 2 guys on this channel?
They quit and made a new channel about cars

You two have good chemistry!
That indeed did answer that.
I bet those rods have a good personality
"So we have the shield on today" pans over to a piece of tin foil.
That water probably smells terrible.
yay you got your waterje back!
I bet those rods have a wonderful personality to boot
It’s been a while since we’ve gotten a tank clean out video, actually maybe on the OG water jet. It would be cool to get another since your tank is getting pretty full of garnet. And maybe get a fresh big bearing to spin with fresh water in the tank
Loved the get smart clip
Are you using garnet or just water? Watched to the end, got my answer.
Idk how long before the jet should be repositioned to only act on the farthest edge as it expands with speed; but I think all of your wheels could spin faster if the jet was moving away from the axle as the plastic expands, so it doesn't cut through the core material while the speed is still increasing.
If you want I work at a plant and some of our bearings are 8-10in inner diameter. If we replace one I could send it out to test? But yea they need lots of grease for those large ones with some kind of shield to keep the grease in. Normally they're pressed into a housing that has a cap you put on after for greasing purposes.
the biggest bearings you've shown are actually quite small compared to the size they could be. The stone crusher at my work already has bearings the size of a basketball
Fun always starts with "We've got the shield set up."
One tip for high speed cameras. Use LOTS of light. Like, alot more light than you think you would actually need.
Ive spun up many bearings with compressed air. The most dangerous ones are tapered roller bearings (any roller bearing i guess lol) Also spun up a squirrel cage blower fan with an industrial steamer/pressure washer.. it did blow up.
When I worked as a mechanic I repacked many tapered roller bearings for front auto wheels,would get that bearing screaming good with compressed air till boss said he did that once and the cage failed and the rollers turned into shrapnel.
you need more light for the slow mo
Back in my younger days, being a mechanic at an exxon gas station, I was repacking the front wheel bearings on a vehicle, in the process i soaked them in some chemtool to clean them, and before packing them with grease, me and my genius mentality figured I would use compressed air to spin them dry and clean of the cleaner....as i started, it made what I thought was a neat sound, a high pitch whine, trying to maximize it I kept the air on for a min.....before i could do much of anything, that damn thing blew up....neay removed my middle finger from my hand and virtually split my thumb in half, and i ended up missing 3 fingernails that moments before had been on my fingers....that had to have been probably THE stupidest thing I have done.....I thank God one of those bearing didnt go in and out of my skull, but waz quite similar to a small frag gernade going off in my hand....all grew back together and only ended up with one odd shaped fingers....but still, it was a neat sound, up untill the moment of decetegration....DO NOT TRY THIS TRICK AS THE REWARD IS NOT WORTH IT
I subscribed for the lick tests there been a lack of the licking lately 😬still subscribed tho
I haven't been to this channel in a while... Who are you two? Where are the other two fellas?
Giant bearing size of human face We have to set up the safety shield or someone is gonna get hurt * *safety shield is unsecured half of a garbage pail* *
Great fun, when I was a kid I did this with compressed air. BTW in the 1 bearing it's not rods, it's called needle rollers. lol
We used to spin those big bearings up with air on a wooden hammer handle, once they got up to speed we would let them go, straight at a concrete block wall. Some would end up exploding against the wall. Got in a lot of trouble when one actually went through the wall, that was the last time we did it.
I am quite happy channels like this exist so I can not have the need to do this level of absurdity myself. I can just watch your video instead.
I've seen a lot of bearings, but none that terrified me at all
“6 inch”, “massive”. Lol 😂
I know this question is not on topic with the video, but can used garnet be dried and used with a hose siphon sand blaster gun? (The kind that is used in some cabinet sand blasters.)
Maybe you should clean out the old abrasive
I miss the lick test and the men who did it. Pat you're great, but i miss the OGS
Do a spinny wheel with the really efficient water cup things to catch more water
It’s obvious from the start that these guys know bupkis about bearings but even then should know bearings work better with grease in them. Their “huge” bearing is actually small. So much to learn. Somewhat entertaining though.
Its not the size of the bearing that makes that one bearing harder to turn. Its the seal. Pop that out and I'd bet it would spin as freely as the larger one though then it would have the issue of the garnet getting inside like your big one did. Also I'd wadger that bearing is new. Those seals will wear in a bit with time in service and will spin more freely up to the point when the grease starts wearing out, then things will turn alot worse. a large motor's speed is not regulated by the bearings, ideally those would be completely frictionless but we have to make do with as close to frictionless as possible. the speed of an AC motor is regulated by the windings and how many cycles per second your power is being feed to the motor. Basicly if the motor is designed to spin at 600 rpm that magnetic field the electricity is generating will be rotating at 600 rpm and the rotor will accelerate to catch up. the rotor cant spin any faster than that magnetic field unless your spining the shaft with something else (such as in a generator) so there is no reason to try and regulate the speed with the bearings. That would just generate extra heat that is already hard enough to get rid of. I couldn't quite read the bearing part number. best frame was still a little smudged but looked like it could have been a 6012 bearing. About right for the stated size as that would be about 3.5inch outer diameter, closer to 2 and 3/8th's inner diameter. You didnt even come close to maxing out the speed on those bearings. I've seen motors come through the shop I work at with service speeds up to 3600 RPM. Some of the larger servo motors I repair can be 6k rpm max with a 6308 bearing in the drive end, the outer diameter would be about that size. Also its kind of cute that you think that 6217 bearing is massive. Had to help install a 6328 a few weeks back. over 12 inches accross and 50 pounds. Thats geting into the large end of what my shop can handle on site as motors big enough to need much larger than that will start maxing out our cranes. but the 6217? theres probably 3-4 used ones of those in our scrap bin at any given time.
A free-spinning bearing is a broken bearing. You do NOT want that.
Y’all need to do another tank cleaning video
What is NPS (or MPS?) and where can I go visit one?
at the company our union is contracted to work for, we use waterjets to cut gating off of aluminum alloy jet engine parts for military and commercial planes :) the only reason i made the connection to this video was because there are garnet tanks stored in an area that was once a work station for manually belting parts
In an engineering class, we had a massive 1 1/2’ breaking that we used as a weight. Must have been for something very industrial
0:43 those are called Needle Bearings Unless you already know and are fucking around lmao
... Is this OSHA certified? That thin film of steel held down with wood screws isn't going to do a thing to the bearing if it comes apart at 2700rpm.
1:20 Yea, scrolling on a Chronos is like that sometimes.
So, it's been a while since I've watched any of your videos, probably 2 years or so. I have no idea who you guys are anymore.
Y'all should hook up with the slo mo guys!!
Perhaps a laugh would be to get the large bearings spinning with air and release them in a big clear area. That big bearing would easily carry enough momentum to go over 100 meters with a cool spray of sparks behind it. Due to the gyroscopic effect the go in a nice straight line as well but when they get the wobbles it looks cool as they explode.
You could put abrasive paper on the outside of the metal ones to give more drag to the water
I wonder if soaking/coating the bearings in a combination of lube and neverwet on the giant industrial bearing would prevent the stoppage?
This demonstration is awesome it reminds when I once fired a 357 magnum at an empty shotgun shell on an iced over pond. I must have glance it just right. It spun for at least a minute and a half then it shot up in the air 30 or 40 feet and came down and spun for another minute or so.
Have you guys tried just using the water pressure or are you using garnett as well?
Does your dad know you're playing with his waterjet machine again?
i was thinking, you could make small notches in the outer profile of the bearing for the water to grab onto and possibly get a higher rpm
Who are these new guys?
In the 50s they sold lead gyroscopes at toy stores. You'd crack open the cage so you could drop the wheel and axle out onto the floor after getting it up to speed with 125psi air. A wonder I'm not dead. Once popped out onto the floor there was no traction so to speak and it would just sit there hopping up and down and moving slowly forward. After awhile some traction would develop and it would eventually shoot out of the garage going like hell...
You guys need to totally collab with The slow Mo guys
Former Boeing Everett... we use ultra high pressure water jets to spin our giant turbofan jet engines to start them.... nah.. just pulling your leg.
Do you think greasing the open bearings would make them hold up better by keeping the garnet out?
Maybe cuz they r supost to be greased, not run dry but the garnet might just gunk it up even more if greased and cause problems.
The bearing with the black plastic shield has grease inside, making it actually useable, the unshielded bearing only spin fast cause they arnt greased, and if used without grease in an actual bearing application would almost immediately destroy themselves, the resistance the grease adds is very negligible, even in high speed applications, it's just significantly more then hardened polished metal on hardened polished metal so it quickly stops free spinning.
First video in a while. Who are these guys. We’re did the old duo go
I would say that not only is the bearing not rated for 40k rpm with grit in it, it is also not rated for use on a shaft with a diamater smaller than the inside diameter of the bearing.
The bearing with the rubber seal is packed with grease, if you removed the seal and cleaned it out it would spin as freely as any other bearing.
You should take out the garnet and do this
