Types of Hydraulic Piston and Rod Seal
1 - Piston Seals
Piston seals are designed to create a tight seal between the piston and the cylinder in hydraulic actuators.
They perform two primary functions: preventing fluid leakage from the pressure side to the low-pressure side and maintaining the hydraulic pressure needed for effective operation.
Piston seals are manufactured to handle high pressures and dynamic movements, making them crucial for efficient hydraulic performance.
Materials:
Polyurethane (PU): Offers excellent abrasion resistance and resilience, ideal for dynamic applications.
