DKBZ is a type of metal wiper seal which used to prevent dust, dirt, sand, and metal chips from entering the hydraulic cylinder.
DHS is pu wiper seal and rubber wiper seal component used in hydraulic and pneumatic systems to protect the internal components from contaminants such as dust, dirt, and moisture.
The DH-5 rubber wiper seal is a type of wiper seal with a sealing lip on the outer diameter, which prevents contaminants from entering the sealing system.
PTFE Wiper Seal of GSZ5 composed of a wearing ring with sealing and dust-proof cutting edges and an O-ring acting as a pre-tightening element.
DKBI is metal wiper seal suitable for reciprocating, oscillating, or rotary motion systems and exhibits excellent dust scraping capability, wear resistance, and long service life.
A hydraulic ram wiper seal, also known as a dust seal、heavy duty rod scraper seal or excluder seal, is installed at the end of a piston rod, forming a tight seal with the rod. Its primary function is to prevent external contaminants such as dirt, moisture, debris, mud, or dust from entering the cylinder when the rod retracts. It helps to avoid contamination and scratches on the piston rod, cylinder wall, valves, or other components and prevents seal failure.
wiper ring seals must be used with other primary sealing elements, such as rod seals, piston seals, and guide rings. They are commonly used in hydraulic and pneumatic cylinders and telescopic suspension forks for motorcycles and bicycles.
Without a rod wiper seal, contaminants can enter the cylinder system, causing rapid wear on other seals, which affects the equipment’s normal operation and service life.
hydraulic cylinder rod wiper oil seals can be classified by design or material. The most common type is the double lip wiper seal, divided into skeleton lip wiper seals and non-skeleton lip wiper seals.
We provide a wide range of PU wiper seals, PTFE wiper seals, metal clad wiper seals, rubber wiper seals, and CNC metric rod wiper seals for selection.
When designing and using shaft wiper seals, contact pressure and angle must be given special consideration. A proper lip interference fit or compression ratio is essential to ensure adequate contact pressure and sealing angle.
Additionally, when the piston rod is stationary, the wiper ring provides static sealing.
TYS wiper scraper seals are made from a variety of robust materials, including:
We use premium materials to ensure efficient dust protection and consistent product stability. Our hydraulic cylinder seals and wipers safeguard core components, optimize overall performance, and enhance mechanical efficiency.
We offer various design structures, including snap-in designs and U-cup press-fit designs. The dust lip is designed with preload contact against the piston rod, ensuring a firm structure. Additionally, the lip is slightly protruded beyond the cylinder head end, facilitating the removal of contaminants blocked by the lip.
The structure is simple and convenient to install, making it widely applicable for general industrial hydraulics, mobile hydraulics, and pneumatics. It delivers maximum dust protection.

When designing and using shaft wiper seals, contact pressure and angle must be given special consideration. A proper lip interference fit or compression ratio is essential to ensure adequate contact pressure and sealing angle. Otherwise, the wiper gland seal may lose functionality or suffer severe wear.
We offer custom wiper seals tailored to your specific requirements, including:

Failure of dust wiper seal can lead to a series of serious problems, affecting the normal operation of the equipment and even causing system damage. The following are common failure consequences and possible impacts:
1/Contaminants entering the hydraulic system
2/Damage to the piston rod surface
3/Internal or external leakage of the hydraulic cylinder
4/Unstable equipment operation and reduced performance
5/Increased maintenance costs and increased downtime
The cycle of replacing wiper seals on hydraulic cylinder depends on factors such as the use environment, working pressure, temperature, and sealing materials. Generally speaking, it is recommended to replace them according to the following conditions:
General replacement cycle: 6-24 months (depending on the working conditions)
In harsh environments: it is recommended to replace them every 6-12 months
Even if the dirt seals are not obviously damaged, it is recommended to check them once a year. Regular maintenance can extend the life of the hydraulic system.
