Hydraulic cylinders are used to power a wide variety of mechanisms, including heavy machinery and industrial equipment. Because this technology has such a wide range of applications, the components come in many varieties as well. Our team at Dalton Hydraulic has extensive experience in working with hydraulic cylinders of all kinds, and we can help you get the right type for your needs. In this article, we will focus on our welded tube hydraulic cylinders, providing a brief overview of how they work.
- Construction – Welded tube hydraulic cylinders get their name from how they are constructed—namely, from the fact that the tube and its end caps are welded together. This is different from tie rod hydraulic cylinders, which are held together with bolts and rods. Welding the end caps to the tube gives this type of hydraulic cylinder more strength and durability than other varieties.
- Function – Welded tube hydraulic cylinders function in more or less the same way as all other varieties of hydraulic cylinders. Specifically, each tube contains a piston, which is attached to another mechanism. To power the mechanism, the tube is filled with hydraulic fluid—as the volume of fluid increases, the piston is pushed to the end of the tube, which in turn applies force to power the rest of the mechanism. This process also works in reverse, with the piston sinking back down as fluid leaves the tube. Once the tube is empty, the process can be repeated, allowing the mechanism to keep going.
