Piston Seals or Piston Rings are used in hydraulic cylinders for fluid sealing and are designed to ensure that pressurized fluid does not leak across the cylinder head as the system pressure pushes the piston down the cylinder bore.
A Single Acting Piston Seal is specifically engineered for cylinders experiencing pressure from one direction only. This design accommodates scenarios where the piston’s exposed side interacts with atmospheric conditions while the pressure side retains oil. This seal must minimize oil transfer during piston movement to prevent external leakage.
In Single Acting Cylinders, the open end can exchange air during piston strokes, potentially introducing moisture and contaminants. To mitigate this risk, vent filters are often integrated into the cylinder’s open side, limiting contaminants from entering the internal space. Additionally, protective measures such as hard chromium plating on the cylinder bore help deter corrosion, ensuring prolonged seal integrity and cylinder performance.
