Wipers

Wipers, also known as scraper seals, play a crucial role in protecting machinery and ensuring efficient operation by preventing contaminants from entering and damaging sensitive components. In various industrial applications, wipers are essential for maintaining the integrity and performance of machinery, thus extending its operational life.

Wipers are specialized sealing elements designed to remove dirt, dust, moisture, and other contaminants from surfaces such as rods or shafts as they move in and out of a hydraulic cylinder or other mechanical systems. By scraping off external contaminants, wipers prevent abrasive particles from entering the system, which can cause wear and tear on internal components. Additionally, wipers help keep moisture out, reducing the risk of corrosion and ensuring smooth operation. They also assist in retaining the necessary lubrication within the system, enhancing the efficiency and longevity of the machinery.

Key Functions of Wipers:

• Contaminant Exclusion: Prevents abrasive particles from entering the system.
• Moisture Control: Keeps moisture out, reducing corrosion risk.
• Lubricant Retention: Retains necessary lubrication within the system.

Wipers come in various types to suit different applications. Single-lip wipers are designed for general applications where light contaminants are present, providing effective sealing with minimal friction. Double-lip wipers offer enhanced protection by providing an additional sealing lip, making them ideal for heavy-duty applications. Metal-cased wipers combine the flexibility of elastomeric materials with the strength of metal, offering robust performance in harsh conditions.

Types of Wipers:

• Single-Lip Wipers: For general applications with light contaminants.
• Double-Lip Wipers: Enhanced protection for demanding environments.
• Metal-Cased Wipers: Robust performance in harsh conditions.

Wipers are manufactured from a variety of materials to suit different applications. Nitrile Rubber (NBR) is known for its good abrasion resistance and compatibility with a wide range of hydraulic fluids. Polyurethane (PU) offers excellent resistance to abrasion and extrusion, making it suitable for high-pressure applications. Fluoroelastomers (FKM) are ideal for extreme temperatures and chemically aggressive environments.

Wipers are essential in a broad spectrum of industries. In the automotive industry, they ensure the longevity and performance of shock absorbers and other hydraulic systems. In agriculture, wipers protect equipment like tractors and harvesters from dust and debris. In construction, they keep hydraulic machinery, such as excavators and loaders, running smoothly in rugged environments. In industrial machinery, wipers maintain the performance of various types of machinery by preventing contamination.
