SSA type face seal, also called end face seal, is a robust static and low-speed rotary sealing component designed for heavy-duty hydraulic assemblies. It adopts paired sealing rings to form a flat contact surface, preventing leakage of hydraulic fluid between two connecting mating faces. The SSA end face seal can withstand axial compression and resist external dirt and moisture intrusion, ideal for applications where radial space is limited.
Constructed with high-quality elastomer and reinforced metal structure, the SSA face seal delivers outstanding compression resistance, wear resistance and stable sealing performance. Its flat sealing surface maintains uniform contact pressure under assembly preload. It can endure pressure up to 32 MPa and works steadily within the temperature range from -30℃ to 100℃. It retains good elasticity even under continuous static pressure and shock loads.
Compatible with mineral hydraulic oil and most common hydraulic media, SSA face seals are widely used in excavator swivel joints, planetary reducers, rotary joints and other engineering machinery components. It fits standard installation dimensions for easy assembly and direct replacement. By eliminating fluid leakage at connecting interfaces and reducing maintenance frequency, the SSA end face seal provides a dependable heavy-duty face sealing solution for hydraulic and mechanical systems.
