Wiper seals
Wiper seals
Wiper seals are used in hydraulic and pneumatic actuators. They play a crucial role in ensuring seal integrity and the effective functioning of pistons in cylinders, minimizing fluid leaks and protecting moving parts from contaminants.
Wiper seals are made from strong materials such as rubber, plastics, or metals, which possess properties that allow for effective sealing and protection of the cylinder from external contaminants.
What function does a piston wiper seals serve?
- Sealing the space: Wiper seals provide effective sealing of the space between the piston and the cylinder, which is crucial in preventing leaks of hydraulic or pneumatic fluids. This minimizes the risk of performance loss and damage to the system.
- Protection from contaminants: Their main function is also to protect the interior of the system from the intrusion of contaminants such as dust, dirt, metal filings, or other particles that can be harmful to moving parts and seals. In this way, wiper seals protect the system components from wear and damage.
- Reducing friction: Furthermore, wiper seals can serve to reduce friction between moving parts, contributing to increased efficiency and durability of the device. By minimizing friction, they ensure smooth movement of the piston in the cylinder, which is essential for the effective operation of the system.
Seals in Our Offer
We offer a variety of seals, including:
- ZZ Seal: The ZZ-type metal-reinforced seal is mainly intended for light applications. The metal reinforcement provides additional strength, but it requires proper fitting into a press-fit housing.
- GHW Seal: The GHW seal is a sealing and wiper ring made of strong polyurethane. Its main feature is effective protection of the piston rod from contaminants and excellent sealing due to the presence of a second lip. It is mainly recommended for industrial cylinders and earth-moving equipment.
- GPA Seal: The GPA seal is a metal-reinforced polyurethane seal designed for heavy hydraulics. Thanks to its durable materials and solid mounting, it is suitable for industrial cylinders and earth-moving equipment.
- GHK Seal: The GHK seal is a basic dirt seal, suitable for both hydraulic and pneumatic equipment. Made from strong polyurethane, it provides effective protection against dirt, liquids, and other contaminants.
- Actuator Seal: The actuator seal is located at the bottom of the cylinder, where the piston rod exits during the operation of the actuator. It also seals the space between the piston and the cylinder, preventing leaks of fluids and contaminants.
Application of Seals
Seals find broad application in various actuators and industrial machines where there is a risk of dirt entering the cylinder. Their main function is to protect the piston rod from contaminants, contributing to the reliability and durability of hydraulic and pneumatic systems.
Seals play a crucial role in ensuring the tightness between the piston and the cylinder, minimizing leaks of hydraulic or pneumatic fluids. This prevents performance losses and damage within the system. Seals are used in various actuators and industrial machines where there is a risk of dirt entering the cylinder. This makes them applicable in many industrial sectors, demonstrating their versatility and adaptability. Seals can also reduce friction between moving parts, contributing to increased efficiency and durability of the equipment. Minimizing friction ensures smooth movement of the piston in the cylinder, which is crucial for the effective operation of the system.
