Wiper Seals for Hydraulic and Pneumatic Applications

Wiper seals, also known as scraper seals, play a vital role in protecting hydraulic and pneumatic systems from external contamination. They are designed to remove dirt, debris, moisture, and other contaminants from the piston rod or cylinder rod as it retracts, preventing these contaminants from entering the system and causing damage to seals, bearings, and other critical components.

Types of Wiper Seals

Lip-Type Wipers

Featuring a flexible lip that scrapes contaminants from the rod surface.

U-Cup Wipers

U-shaped wipers that provide effective wiping action.

PTFE Wipers

Offer low friction and excellent chemical resistance.

Materials

Nitrile Rubber (NBR)

A common and cost-effective choice for general-purpose applications.

Polyurethane (PU)

Excellent abrasion and tear resistance, ideal for demanding applications.

Viton (FKM)

For high-temperature and chemically aggressive environments.

Applications

Hydraulic Cylinders

In construction equipment, agricultural machinery, industrial presses, and mobile hydraulics.

Pneumatic Cylinders

In automation systems, robotics, packaging equipment, and manufacturing processes.

Telescopic Cylinders

Where multiple stages of the cylinder extend and retract.

Key Features and Benefits

Contamination Prevention

Effectively remove contaminants from the rod surface, preventing them from entering the system.

Extended Seal Life

By minimizing contamination, wiper seals help prolong the life of other seals in the system, such as rod seals and piston seals.

Reduced Wear and Tear

Protect internal components from abrasive wear caused by dirt and debris.

Improved System Performance

Contributes to smoother and more reliable operation of hydraulic and pneumatic equipment.

Selecting the Right Wiper Seal

Rod Diameter

The diameter of the piston rod or cylinder rod.

Temperature Range

The range of temperatures the wiper will be exposed to.

Operating Speed

The speed of the rod movement.

Contaminant Type

The type of contaminants the wiper needs to remove.
