FSM Type Face Seal | Heavy Duty Hydraulic End Face Seal for Construction Machinery

FSM type face seal, known as end face seal, is a heavy-duty static and low-speed rotary sealing component specially engineered for engineering machinery. It consists of matched sealing rings that create flat contact surfaces to block hydraulic fluid leakage between two mating connecting faces. The FSM end face seal can bear axial compressive force and stop dust, mud and water from invading the sealing interface, which is perfect for working conditions with limited radial installation space.

Made of premium elastomer combined with reinforced metal framework, the FSM face seal features excellent compression resistance, abrasion resistance and stable sealing property. Its flat sealing surface maintains even contact pressure under pre-tightening assembly load. It can withstand working pressure up to 32 MPa and runs reliably within the temperature range from -30℃ to 100℃. It keeps good elasticity under continuous static pressure and periodic impact loads.

Compatible with mineral hydraulic oil and most conventional hydraulic fluids, FSM face seals are widely applied in excavator swivel joints, planetary reducers, rotary unions and other construction machinery parts. It adopts standard installation sizes for quick assembly and direct replacement. By preventing medium leakage at connection interfaces and cutting down maintenance times, the FSM end face seal provides a trustworthy heavy-duty face sealing solution for hydraulic and mechanical systems.
