UNITED ELASTOMER

Single acting piston seal is designed to have outer lip shorter than the inner lip in order to be used for piston applications.

U seal is a single acting piston-rod seal and designed to have symmetrical lips in order to be used both for rod and piston applications. It is the most critical seal on any type of fluid power equipment preventing leakage of fluid from within the cylinder to the outside. Leakage through the rod seal can reduce equipment performance, and also in extreme cases can cause environmental issue.

Polyurethane (PU) is a special material that offers the resilience of rubber combined with the toughness and durableness. It allows people to substitute rubber, plastic and metal with PU. Polyurethane can reduce factory maintenance and OEM product cost. Polyurethane has better abrasion and tear resistance than rubbers, and offering higher load bearing capacity.

Technical Data

• Operation conditions
• Pressure: ≤31.5Mpa
• Temperature: -35+100
• Speed: 0.5m/s
• Media: Hydraulic oils (mineral oil-based)

Advantages

• Superior static and dynamic sealing effect.
• Wide range of dimensions.
• Easy assembly into closed grooves.
• Simple groove design.
• Economical sealing solution.

Application
Construction machinery, fork lift trucks, injection moulding machines, gricultural machinery, loading platforms and standard cylinders.

Installation
This seal fits easily in closed grooves as per the sizes. You use special tools during installation. But, the assembly tools must be of soft material and have no sharp edges. Otherwise, the seal might gets damaged. Before installation the wiper must be oiled with system oil.

Rod Seal have two sealing lips, inner lip shorter than the outer lip. It prevents leakage of fluid from the cylinder to the outside.

Rod seal is the most critical seal on any type of fluid power equipment. It prevents leakage of fluid from the cylinder to the outside. In addition, it has two sealing lips. Therefore, an additional lubrication is maintained in the sealing gap due to the action of the two sealing lips. At the same time, it prevents the entry of contaminations from the wiper side.  

Application
Construction machinery, fork-lift trucks, injection moulding machines, agricultural machinery, loading platforms and standard cylinders.  

Installation
It fits easily in closed grooves according to the sizes chart. Therefore You should use special assembly tools during installation. But, It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the sealing element must be oiled with system oil.

Hydraulic seal elements have 5 main category: Rod seals, Piston seals, U-symmetrical seals, Wiper seals and guide rings. Hydraulic seals prevent leakage of all types of fluids, while also being characterized by extreme resistance to high pressure, high temperatures and direct force acting inside the cylinder of the machine. The selection of appropriate gaskets for power hydraulics allows for a significant extension of the service life.

Wipers are installed in the sealing configurations of hydraulic cylinders to prevent contaminants such as dirt, dust and moisture from entering the cylinder as they retract back into the system. Contamination can cause significant damage to the rod, cylinder wall, seals, and other components, and is one of the primary causes of premature seal and component failure in a fluid power system.

Advantages

• Good wiping effect.
• Wide range of dimensions.
• No twisting in the housing.
• Wiper lip reliably wipes away dirt and leaves a residual oil film on the retracting rod.
• Double lip makes additional protection to prevent the particles to enter into the cylinder.
• Easy installation.

Application
Construction machinery, fork-lift trucks, injection moulding machines, agricultural machinery and standard cylinders.  

Installation
wiper seal can be easily fitted into the closed housing by deforming into a kidney shape. But, It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the wiper must be oiled with system oil.

EU rod seal for piston rods in pneumatic cylinders combines three functions: sealing-wiping-fixing.

Produced based on the PU material, our EU seals perform an absolute sealing with its dynamic nutring sealing lips and its joint dust lips. Being used safely for all pneumatic cylinders.

Pneumatic seals are using compressed air to seal the gap of the rotating shaft without leaking the working medium. The annular groove is machined on the casing. And the gap of the rotating shaft is blocked by the compressed air to prevent leakage of lubricating oil.

Advantages

• No danger of corrosion.
• No dust corners.
• Low friction values and high length of operation.
• Suitable for use in dry as well as oil-free air after initial assembly lubrication.

Installation
It can be assembled into closed groove with tight hand force. EU Seal does not need additional element such as circlip for axial fitting within the housing. We recommend using special assembly tool. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the sealing element must be oiled with system oil.   All our seals are packed and sealed at the point of manufacture to ensure the highest quality. They are stored out of sunlight and kept in a temperature controlled environment until dispatch.
