Cell doors are usually barred and made of abrasion resistant steel so you won't ever have the time to angle grind your way through the door without getting spotted due to the racket that you would be making.
My front door is metal, 250+ lbs. When it was first installed, the guys didn’t know what to do with the ball bearings and left them out. Within a year, I couldn’t open my front door anymore. Had to cut the hinges, weld new ones, and this second time around, with the balls. Going on 13 years now.
As soon as you load it with the cantilevered weight of the gate the bottom edge of the outer tube will just rub on the inner tube. There a reason why heavy duty industrial hinges have bearings top and bottom.
My question is whether the ball bearing would eventually flatten at the top and bottom. Since there’s not really any force applied that would rotate it about the vertical axis I’d think the wear would be focused to the contact points. It seems like it would work much better if you could have 4 ball bearings in between in a flat arrangement with an appropriate + shaped spacer so they could all roll and experience more-even wear.
@@solvated_photonI mean honestly doubt it would do much since it’s probably just pivoting back and forth. I mean try and flatten a pencils tip out by just spinning it on the tip. There ya go.
@@solvated_photon The fact it’s just a door hinge and its motion will be limited and relatively slow, it’d be a very long time before wear would become any concern. Even with a heavy door I doubt it’d be worn much.
@solvated_photon if anything, it would be the surrounding metal that gets a divot in it given that the mild steel would be softer than the ball bearing
This works and it works well. I used to work in a shop that made metal doors, windows, gates, and more. Every hinge was metal and super simplistic as shown here. When we would be out on the road my boss would show me all the jobs that he had done as we drove by. The hinges never fail! Its always the frame that goes first when it rusts. This was in Mexico by the way.
@@amiznu Be dead easy to pack with a proper lubricating/preservative grease too, but that won't be so good in places where you don't want the eventual mess of grease. Just go with stainless, keep the water off the hinge where possible so you don't get capillary action (between outer and inner parts), and keep the door moving (even once a day should be fine) so there's no chance of seizing.
I have already done this assembly on a very heavy door with two uprights: upper tube in much thicker steel, lower and upper tube do not have flat contact with the ball, it is necessary to "ovalize - round off" the surface with a large drill bit to increase the contact surface. And then fit a grease fitting on the upper tube, even if it is to add grease every 5 years, much better than dismantling a door that weight several hundred kilos.
This transfers the load to two tiny points at the top and bottom of the ball, the ball does not rotate to distribute the wear nor does the post or cap so it will wear out fast. You need a semi-sphere on both ends for it to not wear out fast but this would add much more friction. A thrust bearing would distribute the load much better and radial bearings on the outside diameter of the post would make it super smooth under load but that is over engineering in most applications.
Will it? Weather vanes use this type of bearing, and plain bearings seem to last a bizarrely long time. It seems like it would wear out but I could also see it being perfectly fine with good grease
Its a common design, available at the hardware store. Usually welded onto steel framed gates, works just fine even on heavy gates. Just got to grease them every few years to make sure they dont rust up.
Ok……… What about friction from side load. In this depiction the majority of the forces are evenly dispersed. When the door is attached, the forces will be levered to one side point. This will negate the effectiveness of the bearing.
It's great in theory but there's going to be problems... To start with, you're putting the entire weight of the gate on approx 1/16" of the ball bearing, that's going to wear through the mild steel very fast and reduce that fluid motion to a screeching grind. This is where a flat-pack needle bearing set would be wonderful, same bodies you created only instead of the ball, put in needles.
@@MakeEverything nothing is working for 230 years when your weld looks like a damn caterpillar. Also aside from that it’s way too hot which caused all that undercut. And for the icing on the cake you didn’t even tie in to both sides all the way around the tube or Stud which makes the weld weak. And lastly the weld is so uneven I bet there’s no way in hell it’s center and square with that plate. If there’s pressure on that weld it’ll last less then 2 years 😢😂

Точка соприкосновения обладает минимальным пятном контакта, соответственно нагрузка в этом месте будет стремиться к бесконечности. Работать такая конструкция будет не долго, шарик сожрет более мягкий металл...
If it's welded it needs some sort of adjustment aswell one as much as 10mm backplate on top with a screw that pushes it downwards for adjusting the height, cause that hardened ball will eventually eat through that mild steel and will cause a ball shape on either side and will cause the door to be hanging low. A hole with a rubber cap on the side for greasing purposes too.
You can dispense with the ball bearing if you put the grease zerk into the top of the rotating fitting...and pump up the grease every so often.

The gates still swing open every morning and shut every evening for his son who now owns the property...
Did you not see the perfectly level post with the ball on it that didn't move an inch after he set it down set a marble on any table you own and you know that things going to roll somewhere
Why wouldnt you want multiple smaller balls around the diameter of the inner tube??? Then they would roll with rotation, rather than be two single points of sliding wear....
All the load will be on the side of the pin with a door hanging from it. And you could just machine the top of that pin with a dome; the ball is really unnecessary
@@warifaifai well either way, it needs a zerk fitting so you can grease it. But I disagree with you about the ball, because it’s probably not spinning anyway. Ball BEARINGS are used in a race where they roll. This one will just sit stationary and spin(maybe) which is no different than if it was sitting on top of a crowned pin imo
@@MrLuvtheUSA I've thinking this for a while, there are some things designed for only just one purpose, but I strongly agree that a ball will have a different wear ratio, because of its shape, than a pin so it will require less adjustments over time, just grease. 😮💨 heh all this time thought you were talking bout vertical opening doors
You should look around and realize that a weld doesn't have to look pretty. Plenty of landmarks have some pretty ugly but strong welds. Pretty welds break all the time

@user-bj8se2me5o exactly. A hard steel ball bearing like that, with just a little lubrication it looks like each one of these could smoothly rotate more than 100 pounds, and with 2 or 3 of them per door I highly doubt they'd seize up at all unless the seal wasn't good and they stared corroding
Seen this exact design on steel gates usually heavy weighs or long in size. Much better than standard friction hinge u talking straight out of crapshooter..

High quality door hinges already use a ring of ball bearings trapped between the hinge fingers. Those bearings carry force both downwards and upwards, and those bearings can be replaced when the hinge pin is pulled out. Also the ring bearings are infinitely easier to lubricate, since you don't have to remove the door to get at them.
Hang a 300# gate off that and the tiny contact point is going to start wearing through the cap on the end of that sleeve. If that cap is .250" thick, it will just take longer
For example the state of Florida has a exhibit of the hing at coral castle the stone door that opens with a touch of a finger pivots at the top and bottom.
@@MakeEverything I bet you could make an impression by hitting it real hard with a hammer right on top. Just a couple mm diameter should work. You might need a spare ball for this. I dunno, you might not.. they're usually pretty hard.
A warehouse pallet jack works the same way. About a half inch solid metal ball is used above and between the raising cylinder and the jacks chassis, giving the handle the ability to turn and steer
You'd have to use seamless telescoping tubing, which you won't find in the big box stores. Isn't there also a moment load? This is only showing direct vertical down forces.
You can certainly apply physics to a hinge. Say for instance that hinge is holding a heavy metal gate it's going to have two forces acting on it at any given time. Your gonna have a downward force acting on the bearing. Somewhere you will have a moment acting on the sides of the pin. Where the moment is located ? You need some information to calculate that. Weight, length of the gate,,,, To be better efficient, a roller bearing should be used on the top and bottom of the pin. Instead of a large single bearing up top, a roller bearing thrust washer would be more suitable. Again, depending on weight of course. And thirdly, I really sucked at physics. I'm just shooting out my azz. I'm a fabricator, i just know what works and what doesn't.
Surprisingly enough when I finished the job and plug welded these inside square tube posts they didn’t move enough to effect the smooth action, got lucky,twice!

Ohhhh myyyyy gosh!!! Now I have a use for all those big ball bearings I've horded all these years 😅 That's such a good idea! Smooth and good load bearing!
My wife wants a bookcase hidden door. This would be the perfect hinge with a race turned in the side of the pin for bearings then tig it together.. Good post Thankyou.
you need to at least put a rod to offset the bearing from the center of rotation so it has a secondary rotation component so it doesnt wear at the top.
Need at least a fixed sealed ballbearing set at the bottom and a 2nd one in the middle of the hinge if you want to use steel ball as a 3rd "bearing at the top, whilst no grease at the top will certainly lead to more friction, therefore more wear and tear
U on crack mate? Standard design used on architectural gates world over if they are heavy or high spec. Typical use could be normal pin hinge used up to 200kg this one used over 200kg. Obviously grease nipple is nice but gates do not spin at 10000 rpm so will not wear for life of the owner or his grandkids with or without a grease nipple...

Thank you for the knowledge
Add a zerk for grease it needs greased several times a year.
Grease will make it sticky and it won't work it's air
Why wouldnt you want multiple smaller balls around the diameter of the inner tube??? Then they would roll with rotation, rather than be two single points of sliding wear....
Welding project not Engineering. 🤣
Thanks for sharing. That's exactly what I needed that idea. Thanks again. I really appreciate this one.
Wonderful thing about prototypes, they are the beginning of something much greater.
All the load will be on the side of the pin with a door hanging from it. And you could just machine the top of that pin with a dome; the ball is really unnecessary
The pin will degrade faster than a spinning ball though. It'll be worse with a heavy door hah
@@warifaifai well either way, it needs a zerk fitting so you can grease it. But I disagree with you about the ball, because it’s probably not spinning anyway. Ball BEARINGS are used in a race where they roll. This one will just sit stationary and spin(maybe) which is no different than if it was sitting on top of a crowned pin imo
@@MrLuvtheUSA Zerk as in a Grease Nipple in the UK.
@@MrLuvtheUSA I've thinking this for a while, there are some things designed for only just one purpose, but I strongly agree that a ball will have a different wear ratio, because of its shape, than a pin so it will require less adjustments over time, just grease. 😮💨 heh all this time thought you were talking bout vertical opening doors
YUOP TEUE TRUE!
that's a nice fitting table and some atrocious welds 😝
How come the Alemite fitting hole you drilled is so offset
That's why my front swing gate rides on
The welds💀
LMAO they got the job done to test an idea 🤷🏽😂
You should look around and realize that a weld doesn't have to look pretty. Plenty of landmarks have some pretty ugly but strong welds. Pretty welds break all the time
Not a pressure vessel.
OhMyGosh!!! It looks like I welded it, Only better!
😮 HOW DARE YOU DO THAT WITH NO LUBRICANT!
That's what she said
Even small sized thrust bearings (the size to fit in the tube) would last longer than this setup.
У меня по такому принципу сделаны навесы на воротах гаража.
Один шар будет работать лучше, чем упорный подшипник с мелкими шариками
Even bare steel on steel with some heavy grease will last an eternity😂😂 and if used heavily i rather just slide a brass insert in it. Selflubricates.
You can dispense with the ball bearing if you put the grease zerk into the top of the rotating fitting...and pump up the grease every so often.
A neighbour built two wrought iron gates weighing 400kg each and constructed this greaseable hinge system 40 years ago....
The gates still swing open every morning and shut every evening for his son who now owns the property...
@@JohnSmith-pl2bkи насколько легче это было бы с шариками
Once weight is applied there will be added friction and the ball will seize. Without a bump stop for clearance this won't work
It’s an air door
Not before the engineered point. Materials Hardness being the factor.😮
@user-bj8se2me5o exactly. A hard steel ball bearing like that, with just a little lubrication it looks like each one of these could smoothly rotate more than 100 pounds, and with 2 or 3 of them per door I highly doubt they'd seize up at all unless the seal wasn't good and they stared corroding
Looks like ignorance is your strong suit
Seen this exact design on steel gates usually heavy weighs or long in size. Much better than standard friction hinge u talking straight out of crapshooter..
The way these work is by leverage they can have a crapton of friction in the single point they touch
Which grinds falt the ball bearing or the mild steel "pin" holding the ball nearing up...

all i see is a steel ball, no bearing
The ball is bearing the load. Therefore it's a ball bearing.
@@Gooie69 then whats a ball bearing if the ball is a ball bearing?
It is a loose bearing. The ball for thd axial and the mantle surface is a sliding bearing, which will wear at the bottom edge if tilted.
After welding behind the pipe by deformed and don't spin anymore
Just run a hone or reamer through it afterwards
Still needs a grease fitting
I've been doing things like this since I was five I'm 35
Reported
@@panchopistol6897and for what reason, exactly?
High quality door hinges already use a ring of ball bearings trapped between the hinge fingers. Those bearings carry force both downwards and upwards, and those bearings can be replaced when the hinge pin is pulled out. Also the ring bearings are infinitely easier to lubricate, since you don't have to remove the door to get at them.
My dad used to make heavy duty hinges like this. Filled me with axle grease , smooth as butter barn doors for decades
I'm a jeweler, and I've seen safes you can walk in to with doors that didn't quite make sense until now.
Looks pretty damn avg
This will wear out fast. Not how ball bearings are meant to be used
😂 That's why this is how pallet jacks are able to steer.
Hang a 300# gate off that and the tiny contact point is going to start wearing through the cap on the end of that sleeve. If that cap is .250" thick, it will just take longer
This has been working for 300 years under constant load.
@@MakeEverything Where?
@@stpbasss3773 no it isnt. this is not at all how those bearings work
For example the state of Florida has a exhibit of the hing at coral castle the stone door that opens with a touch of a finger pivots at the top and bottom.
Should have a concave fitting in both ends to prevent uneven wearout
But why would I want increased surface area contacting the ball?
To distribute the Bearing wearout.otherwise it Will get flat and wont do what its supposed to do.
@@MakeEverything I bet you could make an impression by hitting it real hard with a hammer right on top. Just a couple mm diameter should work.
You might need a spare ball for this. I dunno, you might not.. they're usually pretty hard.
@@MakeEverything for the same reason inner races are a hemisphere and not flat. to reduce flat wear
For load distribution you would be better off having a bunch of smaller balls rolling on a pair of concave tracks loaded with grease.
A warehouse pallet jack works the same way. About a half inch solid metal ball is used above and between the raising cylinder and the jacks chassis, giving the handle the ability to turn and steer
Never been done before.
Big door
Where's the zerk going to go?
Definitely using this for anything I build
Needs a grease zerk on top
You'd have to use seamless telescoping tubing, which you won't find in the big box stores. Isn't there also a moment load? This is only showing direct vertical down forces.
Unless it’s a well balanced revolving door…..🤪
You can certainly apply physics to a hinge. Say for instance that hinge is holding a heavy metal gate it's going to have two forces acting on it at any given time. Your gonna have a downward force acting on the bearing. Somewhere you will have a moment acting on the sides of the pin. Where the moment is located ? You need some information to calculate that. Weight, length of the gate,,,,
To be better efficient, a roller bearing should be used on the top and bottom of the pin. Instead of a large single bearing up top, a roller bearing thrust washer would be more suitable. Again, depending on weight of course. And thirdly, I really sucked at physics. I'm just shooting out my azz. I'm a fabricator, i just know what works and what doesn't.
The way the outer tube softly ran down the inner tube was so satisfying
Don't let my ex wife see that
Just don’t weld the outside of the sleeve, you’ll distort the cylinder and it won’t have the same clearance.
Surprisingly enough when I finished the job and plug welded these inside square tube posts they didn’t move enough to effect the smooth action, got lucky,twice!
@@MakeEverythingcan you post a video of the finished product? Thanks
Needs a grease zerk
Yes just a hole with a rubber cap on the side, first thing that i thought

Those are some pretty tight tolerances, the way it slide down so slow. Props to the machinist.
Ohhhh myyyyy gosh!!! Now I have a use for all those big ball bearings I've horded all these years 😅 That's such a good idea! Smooth and good load bearing!
Nice idea
I've been doing this for 50 years🥃😎👌
My wife wants a bookcase hidden door. This would be the perfect hinge with a race turned in the side of the pin for bearings then tig it together.. Good post Thankyou.
the door on my safe uses this exact style design.
you need to at least put a rod to offset the bearing from the center of rotation so it has a secondary rotation component so it doesnt wear at the top.
Not neccesary
Add a couple zert fittings and call it a day
Zerks?
@@davidlabossiere1140 yep, thanks, stroke brain really sucks sometimes.
Need at least a fixed sealed ballbearing set at the bottom and a 2nd one in the middle of the hinge if you want to use steel ball as a 3rd "bearing at the top, whilst no grease at the top will certainly lead to more friction, therefore more wear and tear
U on crack mate? Standard design used on architectural gates world over if they are heavy or high spec. Typical use could be normal pin hinge used up to 200kg this one used over 200kg. Obviously grease nipple is nice but gates do not spin at 10000 rpm so will not wear for life of the owner or his grandkids with or without a grease nipple...
Took the idea of a ball bearing hinge (already exists) and spent 20 minutes to make one. You go girl.
Brilliant . Less is more
