Massive Industrial Bearing Spun With 60,000 PSI Waterjet 

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!

Turn into an adult and these are my saturday morning cartoons.

Bring back Dan and Mitchell !!!

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.

The big bearing was supposed to be packed with grease and it was missing a seal. It's meant for low speeds as well

Those rods are definitely above average. Arguably could even be considered large.

Starting the bearing spinning with your hand was friggin terrifying

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!?

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?

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.

Sticking your hand under that nozzle with someone ready to turn it on was the stupidest thing you can do.

Who the hell are these guys??? Where are the OGs i remember??

"Stop using abrasive!!" Bro, if they were using abrasive there wouldn't even BE a wheel.

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

What happened to the original host these new guys are trying to hard and messing things up

you should get the slo mo guys in with a 4k phantom camera

Where did Dan and Mitchell go?

Niiice, glad to see the revisit with bearings! Good stuff guys!

still no lick test 😡😡😡😡 bring the OG guys back

Always look forward to Saturday mornings to see these vids

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.

I don't know why things spinning super fast is so intriguing

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.

It's time to clean out the water jet

the sound of the wheel being spun by the air compressor at 1:44 really reminded me of a 2JZ or an RB28 lol

"Usually you don't want things weighing 1000's of pounds spinning at 1000's of RPM" lol

you guys should make shorts, this type of content is perfect to recut into shorts alongside the main vids :)

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* *

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?

Man I was here to this channel when you were 10k subs, road to a million here we goooo

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.

I bet those rods have a good personality

Would have helped the needle bearings if you used the correct shaft size.

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.

You two have good chemistry!

That indeed did answer that.

3inch is a sealed bearing so it’s packed with grease that’s why it goes slower

"So we have the shield on today" pans over to a piece of tin foil.

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

Loved the get smart clip

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.

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

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!

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 bet those rods have a wonderful personality to boot

yay you got your waterje back!

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.

What is NPS (or MPS?) and where can I go visit one?

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

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.

That water probably smells terrible.

I've seen a lot of bearings, but none that terrified me at all

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

What if y’all cut some thin grooves in the metal barring (horizontally for traction)?

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.

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

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

I haven't been to this channel in a while... Who are you two? Where are the other two fellas?

Fun always starts with "We've got the shield set up."

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.

Are you using garnet or just water? Watched to the end, got my answer.

I wonder if soaking/coating the bearings in a combination of lube and neverwet on the giant industrial bearing would prevent the stoppage?

Maybe you should clean out the old abrasive

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.

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 RU-vid channel. Keep up the good work, I really enjoy this channel.

would you guys consider spinning a cable pully that has dual bearings if i make a shaft for it to ride on....? its about 12-16 inches in diameter.....

“6 inch”, “massive”. Lol 😂

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.

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

One tip for high speed cameras. Use LOTS of light. Like, alot more light than you think you would actually need.

Have you guys tried just using the water pressure or are you using garnett as well?

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

A free-spinning bearing is a broken bearing. You do NOT want that.

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.)

1:20 Yea, scrolling on a Chronos is like that sometimes.

What if you try the bearing thing again but machine some knurling on it or something?

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

need to cut some little grooves in the bearing so the water has something to grab onto

I wonder if the wheel would last longer if the water jet was moving away from the wheel as it expanded

I wish I could send some of the bearings we use, they're 1850mm outside to outside, and sometimes larger if the press were taking apart is considerably more large.

Do a spinny wheel with the really efficient water cup things to catch more water

Do you think greasing the open bearings would make them hold up better by keeping the garnet out?

You could put abrasive paper on the outside of the metal ones to give more drag to the water

Does your dad know you're playing with his waterjet machine again?

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.

That conical bearing is the exact same bearing used in ch-47’s. How did you guys find yhat

Y'all should hook up with the slo mo guys!!

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.

Can you do it pls next time with an FLIR cam?

What about welding some little plate on the Big bearing to make a sort of waterwheel ?

The first min and a half makes it abundantly clear you know absolutely nothing about bearings

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 need more light for the slow mo

You definitely need The SlowMo Guys.

Needle bearings, tapered bearing, deep groove ball bearings etc, boys.

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.

Use a sealed bearing Pop the seal Use brake cleaner Put the seal back on No garnet in bearing Spin faster Use retaining compound on inner race to prevent rotation on tube
