Picking out a Guden caster can sometimes be tricky, maybe just because there are so many varieties and sizes or maybe because so many different types can do the trick for you. Of all the determining factors, weight is probably the most important. No one wants a something with wheels that doesn’t roll! The two dimensions on a caster wheel that help determine the weight load are the wheel diameter and tread width. And just like you’re thinking, yes, the larger the diameter and wider the tread, the more weight the caster can support, and don’t forget that you’ll most likely have 4 casters on your application to help distribute the weight as well. Think about a tractor trailer for a minute. Most have up to 18 or more wheels right? Certainly the truck could move just with 4 wheels like your standard car, but adding more wheels helps support more weight. Check out all the stock Guden / Wagner casters here: http://www.guden.com/ItemDisplay/Casters, and Guden can supply any Wagner item number as a custom request.
For Ice Cream! What would summer be without stopping in to your favorite store for a delicious frozen treat! And in this case, this Hinge Whisperer was also treated to a frozen length of continuous hinge riveted to the protective door over the ice cream selections. I may have even ordered a scoop of the mint chocolate hinge before I realized my mistake. LOL But looking at the hinge I could easily see the in-line holes on both leaves and then noticed that instead of all full knuckles, this designer specified balanced ends. You can see the partial knuckle more clearly on the left side of the picture. So why the partial end knuckles I pondered as they were scooping out my treat. I couldn’t actually measure them, but it looked like the two partial knuckles could have easily been eliminated and just been an all full knuckle hinge. I guess it could have been for retaining the pin since the partial knuckles were a little crushed and were on the same leaf so the hinge didn’t bind. Or maybe the designer just wanted them. I’ll never end up knowing, but then again enjoying a cool ice cream treat seemed to be the more important issue at the time anyways.
One of the more elusive of the hinge pin retention styles is the coined pin. It’s easily identified by it’s flattened end which in most cases is used to hold the pin inside the barrel of the hinge because the flat part is wider than the inside diameter of the hinge barrel. They’re just a rarity to spot roaming free. Because the coined pin is on the inside of the barrel, only the most devout Hinge Whisperers who take the time to inspect a hinge from that angle usually spot them. But in this case, no deep jungle stalking was even required because there it was, right out in the open while I was checking out some shelter cats and dogs. Among all the beautiful creatures I expected to see there, I never expected to stumble upon this unique animal! In front of all the cages were a pair of take apart hinges with a hinge pin in place to hold the two hinge leaves together. But oh no, it wasn’t the standard spun pin end I was seeing, it was most certainly a coined pin variety. The flattened metal sticking out above the hinge barrel made it easy to tag this rare beast. But why use a coined pin here, I wondered. Sure, a spun pin end is the more common way this hinge arrangement would be found in the wild, and would have certainly done the job just as nicely, but when interviewed, members of the staff all heartily agreed the flat part of the pin made it easier to grip and pull out. So there’s the reason! Just proves you can’t ever stop learning more things about hinge and hardware! And the easiest place to learn is the Guden Hinge Guru site! www.hinges.com
And please don’t forget the pets in our shelters! It would be wonderful if you could give one of these beauties a forever home, but if you aren’t able to, they also accept donations, food, treats, and most certainly welcome visits to give love and attention to some lonely caged animals. And while you’re there, keep your eyes open for unique hardware sightings.

When specifying countersunk holes in your hinge, you can call them out in a few ways. The most common way it just strictly calling out the flat head screw size you are expecting to use like #6FHS or #8FHS. Every good machinist will know exactly what size hole and countersink to do so that the screw fits flat into the hole. The other way for calling out the countersunk holes is specifying all the dimensions. You would call out the hole diameter A with the countersink angle C or you can call out the countersink diameter B with the countersink angle C. Either way, you’ll automatically get the other dimension that you’re missing strictly by the math. You’re probably thinking that you can also call out all 3 dimensions which you certainly can, but most often it’s just the countersink dimension and angle that is most important so the screw will fit flat on the surface. And certainly, as all good engineers know, the more dimensions that are called out that are dependent on each other, the more risk for them not all coming together depending on the tolerances you’re specifying the dimensions to be held and still holding to the standard hinge production practices. As with most hinges, overkill on dimensioning just leads to higher priced hinges!
Guden’s resident Hinge Whisperer truly loves reader submissions, especially odd and unique hinge sightings! And this week’s top Hinge Whisperer sighting submission pours straight out of the brewery. It’s certainly not surprising to me to see a hinge in a brewery, but sure enough, this fantastic sighting submission shows me that the conveyor belt moving the beer around the brewery packaging area is actually a multi-leaf hinge! Even without stopping in the tasting aisle, I’m sure it could cause a little dizziness just watching this conveyor belt snake it’s way around the brewery. Each section is part of a 3 knuckle construction hinge with a pin running through the knuckles to connect them together. The outside edges are angled so that the leaves could move from left to right as needed to negotiate curves, and rounded edges to flip over and underneath the surface and travel back to the start of the conveyor. It’s definitely a fantastic example of a multi-leaf hinge. Though most of the multi-leaf hinges Guden has supplied are just 3 or maybe 4 leaves, this proves that the possibilities can truly be almost endless for how many leaves you could connect together. Thanks again for a great picture to highlight the distinct multi-leaf hinge features of this convey0r belt. Keep those submissions coming!
Every good Hinge Whisperer knows to keep their eyes open everywhere they go for a good sighting and during a good cardio and leg workout the other day was no exception. My eyes as well as my legs were getting a workout looking for good hardware anywhere they could spy it. And sure enough, while doing a grueling exercise on this machine of death, I mean endless stairs, I started wondering how the stairs actually worked as they continuously and endlessly flipped around to keep torturing the user. Then it came to me. So I happily hopped off it and checked the stairs out from the side and there was my sighting! Now this certainly isn’t the normal hinge you’d find, but it is indeed a hinge! Two leaves, the steps, and a connecting pin. That’s the definition of a hinge as we know it. The two panels rotate around the pin creating each step and then refold the other direction to rotate underneath then back around to create the endless suffering, I mean stairs. It just goes to show that almost everything that moves or pivots is on some kind of hinge. So keep your eyes open and you’ll be sure to spot one!
The sky’s the limit or so it seems with this huge length of hinge. At first I thought it was just a joint in the building structure, but upon closer inspection it was indeed a hinge. I could see the distinct knuckles intertwining around the pin with the leaves welded to the frame. Gargantuan! It was at least .50″ thick and it stretched a good 12 feet high. It was challenging even for this Hinge Whisperer to get this much of the hinge length in the shot. You can see how it compares to the door in the background. Truly a sight to behold. It’s almost impossible to think of a hinge being made this big, but with so many new technologies available for hinge production, Guden can offer super long lengths of super thick continuous hinge. Splicing hinge leaves together with multiple pins can make even our longer hinge lengths even longer. So don’t let length stop you now!
Specifying the size and pressure of the gas spring or damper is just part of designing the unit into your application. You also need to decide on how you are going to mount the gas spring to the door or cover and to the base or frame. For gas springs that have a socket end fitting on both ends, they will require some sort of ball mounting hardware.
The most popular is a threaded ball stud that slips through a hole and is nutted from the other side to secure the mount. Sometimes the ball stud can be installed in a threaded hole or a PEM stud as well.
Another method is a flat or angled bracket for when you may not have the room for the ball stud. Brackets also come in various heights for applications that may require a pivot point higher than the mounting surface for a better angle and maximizing the lift of the gas spring.
Gas springs that have blade end fittings are installed over a post of some sort and require less hardware for mounting. Most fit over a rod that is incorporated into the lid and chassis.
