The shaft seal K 55041 is a precision sealing component designed for rack K 55006 in the Sulzer ZV40/48 engine, ensuring effective sealing around moving shaft elements within the fuel control system. Its primary function is to prevent leakage of lubricants or fuel while protecting internal components from contamination by dust, moisture, and external particles. Engineered for operation under continuous movement, vibration, temperature variation, and exposure to fuel and lubricating media, the seal maintains reliable elasticity and sealing performance over extended service intervals. Manufactured from high-quality elastomeric and wear-resistant materials, it provides excellent resistance to friction, pressure, and chemical degradation. Precise dimensional tolerances ensure proper contact with the shaft surface and stable operation. By maintaining sealing integrity and protecting sensitive internal assemblies, the K 55041 shaft seal contributes to reliable fuel system operation, reduced maintenance requirements, and long-term engine reliability.
