Pneumatic Wipers / Scrapers
Wiper seals are also known as Scraper seals. They tend to be used in conjunction with other sealing elements. Wiper seals create a tight fit whilst still allowing a reciprocating ram rod to pass through the inner bore of the seal.
Despite it’s important function, the wiper seal is possibly the most undervalued seal type in the pneumatic cylinders.
Wiper seals are used to eliminate contaminants such as moisture, dirt, and dust. Contamination can cause significant damage to the rod, cylinder wall, seals, and other components. This is one of the primary causes of premature seal and component failure in a fluid power system.
Some Wipers or Scrapers have a secondary lip used to capture any oil that may have bypassed the main seal. The secondary lip may also remove any bonded contaminate from the rod surface. These types of wipers are often called ‘double-edged wipers’.
The common compound for wipers is polyurethane. Metallic scrapers may be used for sub zero temperature applications, and particularly arduous applications where foreign materials can deposit on the rod.
Pneumatic Wiper Seal - type AS
Pneumatic Wiper Seal - type AS The offered pneumatic scraper seal of type AS is a dirt wiper with metal housing; wiper lip protruding. Wiper seals are usually used on hydraulic and pneumatic cylinders and on motorcycle and bicycle telescopic suspension forks. There are many types of wiper seals required to prevent pollutants from reaching the container. External damage, in addition to clear corrosion to the rod seal, may have devastating effects if allowed to penet..

What are the primary functions of pneumatic wipers/scrapers in pneumatic cylinders?
Pneumatic wipers, also known as scraper seals, serve a crucial role in pneumatic cylinders by preventing the ingress of contaminants such as moisture, dirt, and dust. They create a tight fit while allowing the reciprocating ram rod to pass through the inner bore of the seal, ensuring optimal performance and longevity of the cylinder. Effective wiper seals protect other sealing elements and maintain the integrity of the pneumatic system.
How do I choose the right type of pneumatic wiper seal for my application?
Choosing the right pneumatic wiper seal depends on various factors, including the operating environment, the type of contaminants present, and the specific dimensions of your cylinder. For instance, if you require a seal that provides excellent compatibility with various lubricants and high resistance to wear, you might consider the Pneumatic Wiper Seal - type AS. It's important to consult technical specifications and compatibility charts to ensure optimal performance in your specific application.
What maintenance practices should be followed for pneumatic wiper seals?
To ensure the longevity and effectiveness of your pneumatic wiper seals, regular inspection and maintenance are essential. This includes checking for signs of wear or damage, ensuring that the seals are properly lubricated, and confirming that the sealing surfaces are clean and free of debris. Additionally, replacing wiper seals promptly when they show signs of deterioration can prevent further damage to the pneumatic system. For specific replacement options, consider the Pneumatic Wiper Seal - type ASOB.
