What is Stefon?

Nowadays, there are still many people who do not understand some basic information of Stefon, so as a manufacturer, it is necessary for us to briefly explain it. In fact, this Stefon is a kind of existence that we can see everywhere. Its structure is unique, with high external pressure resistance, strong impact resistance and flexibility. So what exactly is Stella?

Now there are many peopleStefonSome of the basic information is unknown, so as a manufacturer, it is necessary for us to briefly explain it. In fact, this type of seal can be seen everywhere. It has a unique structure, high external pressure resistance, strong impact resistance and flexibility. So what exactly is Stella?

So what type of sealing ring is the seal? Let's take a look at it together. First of all, we know that the seal is a sealing ring for single-acting shafts. Its static surface material, that is, the O-star ring, is made of nitrile rubber NBR with a hardness of 70 ° ShA. Usually the seal is generally composed of a rubber O-ring and PTFE ring combination. Its dynamic surface material, that is, the slip ring, is made of polytetrafluoroethylene (PTFE) and bronze. We can choose different materials and equipment according to different working environments. You can also choose the material of the O-ring according to different working environments. Here, the O-ring is mainly a force element, which can provide sufficient sealing force and compensate for the PTFE ring. Its new model is 2K-type Stern seal, and the materials used are Tekang sealing ring and O-ring, so Stern seal is a single-acting seal, which is divided into Stern seal for piston and Stern seal for piston rod. Moreover, it has low friction resistance and does not cause crawling, which is much more convenient during use. At the same time, the seal is also suitable for sealing the piston rod of hydraulic cylinder. And in the industry, the specifications of the seal also have many choices, because in the grid ring, it is suitable for hydraulic cylinders with a large diameter of 2500mm, while the seal is suitable for any piston and piston rod with a large diameter of 1330mm. Therefore, when you buy, you can make a purchase according to your own needs. Our purpose is to let everyone choose their own suitable products, so as to give full play to greater benefits.

Then, of course, Stetseal has some irreplaceable advantages of other products, such as low friction, no crawling, small starting force, high pressure resistance, simple groove structure and other advantages are all preferred by enterprises, and there is no stiction, and the dynamic and static sealing effects are quite good, and their performance will be played well when there is lubrication and no lubrication, therefore, the seal is mostly used for reciprocating plunger and piston rod, such as presses, excavators and metallurgical machinery, as well as loaders and chemical machinery and so on some occasions can see their figure. And can also be applied to a variety of stroke and a wide range of fluid and high temperature occasions, can be suitable for larger piston rod clearance.
