What do you know about hydraulic seal

A hydraulic seal is the most important device of mechanical machinery. Any industry sector that runs hydraulic applications such as aviation landing gear, reciprocating pumps, combustion engines and so on, need these seals to carry out specialized functions. It is a gasket-like structure typically used to seal the high pressure and hydraulic fluid present inside a hydraulic cylinder. Normally, it is made up of two types of materials such as polyurethane and rubber. The use of these materials mandates the specific amount of heat or pressure the seal is ideally subjected to undergo when in use.


The simple principle of work

Since hydraulic seals are available in two types namely dynamic and static seal, the principle of work orbits based on the same properties. This seal is fitted onto the inner hydraulic cylinder shaft and is conveniently sealed against the outer cylinder case. When the hydraulic fluid streams into the hydraulic cylinder, a high pressure is created inside the system that is only wielded by a hydraulic seal

The static-type of seal is a non-moving seal and is fitted within the groove of the system. Due to its stationary mounting design, this type of seal has a lot of capacity to withstand a huge amount of pressure. On the other hand, a dynamic seal is used in the inner shaft of the cylinder and can withstand movement against its inner opening.

All in all, hydraulic seals are very useful devices in industry sectors. They effectively prevent the leaking of hydraulic fluids and rules out the Premium quality PFC-1 Cotton Fabric Phenolic Wear Rings China factory wholesale need to replace or rebuild a damaged cylinder.


There are plenty of tools and equipments that are required to carry out industrial and manufacturing processes. The hydraulic seals are one such useful tool that can be used for a number of different purposes. There are, in fact, different hydraulic actions, and each of these actions requires the usage of specially designed tools. These seals are designed to assist in transferring power from a hydraulic system to the linear motion by containing the oil for the pressure. If the oil is not controlled, the pressure within the system will pass, and this in turn, will result in the failure of the entire system. In addition to that, these seals can also keep away the dirt from the system, by means of which the entire hydraulic action remains efficient.

Different Designs to Suit the Requirements of Industrial Process. There are, in fact, three different types of hydraulic seals, and these seals can be used for different purposes. These include the rod seal, the piston seal and the wiper seal. As the name implies, the function and usage of these seals are also different. However, often these different seals are also used together to serve a specialized function. In the recent days, there has been such a technical progression that these seals can be used in combination to serve a greater purpose.


Usage along with Other Tools.

Apart from these seals, there are other tools also available that can be used to perform other functions. For instance, the O-rings are also one of them. These can not only be used as sealing elements, but at the same time, these can also be used to offer energetic element to the seals and wipers associated with hydraulic action. This in turn, gives an indication that these can also be used in wide varieties of fields in an industry ranging from automation to aerospace to even general engineering.
