Product Description

Wiper seals, also known as scraper seals or dust seals, are components used in hydraulic and pneumatic systems to prevent contamination from entering the system. They are typically installed on the external side of a cylinder or piston rod and serve to wipe away dirt, dust, moisture, and other particles that could potentially damage the system.

Here are some key features and functions of wiper seals:

Contamination Prevention: The primary function of wiper seals is to prevent external contaminants such as dust, dirt, mud, and moisture from entering the hydraulic or pneumatic system. This helps maintain the cleanliness of the system's internal components, thereby prolonging their lifespan and ensuring smooth operation.

Protection: Wiper seals provide a protective barrier for the primary sealing elements of the system, such as piston seals or rod seals. By keeping contaminants away from these critical components, wiper seals help prevent premature wear and damage, ultimately extending the overall service life of the system.

Material Selection: Wiper seals are typically made from elastomeric materials such as nitrile rubber, polyurethane, or silicone, depending on the specific application requirements. These materials offer resistance to abrasion, tearing, and various chemicals commonly encountered in industrial environments.

Design Varieties: Wiper seals come in various designs to accommodate different operating conditions and installation requirements. Common configurations include single lip, double lip, and multiple lip designs, each offering specific advantages in terms of sealing efficiency and debris removal.

Installation: Wiper seals are usually installed in a housing or groove on the external side of the cylinder or piston rod. Proper installation is essential to ensure effective sealing and reliable performance. Additionally, proper lubrication may be necessary to reduce friction and extend the seal's lifespan.

Maintenance: While wiper seals are designed to provide long-term protection and reliability, regular inspection and maintenance are still important to ensure optimal performance. Periodic checks for wear, damage, or contamination buildup can help identify potential issues early and prevent costly downtime or system failures.
