JX type face seal, also referred to as end face seal, is a heavy-duty static and low-speed rotary sealing component engineered for engineering machinery. It consists of paired sealing rings that form flat contact surfaces to prevent hydraulic fluid leakage between two mating connecting faces. The JX end face seal can withstand axial compression and block mud, dust and water from invading the sealing interface, making it ideal for assemblies with limited radial installation space.
Made of high-performance elastomer reinforced with metal framework, the JX face seal features excellent compression resistance, abrasion resistance and consistent sealing stability. Its flat sealing surface maintains uniform contact pressure under assembly preload. It can endure working pressure up to 32 MPa and operates reliably within a temperature range from -30℃ to 100℃. It retains good elasticity under continuous static pressure and repeated impact loads.
Compatible with mineral hydraulic oil and most common hydraulic fluids, JX face seals are widely used in excavator swivel joints, planetary reducers, rotary unions and other construction machinery components. It adopts standard installation dimensions for convenient assembly and direct replacement. By eliminating fluid leakage at connection interfaces and lowering maintenance frequency, the JX end face seal provides a reliable heavy-duty face sealing solution for hydraulic and mechanical systems.
