Heavy Machinery Oil Seal is compositely molded with high-density heavy-duty exclusive rubber formula and thickened integrated reinforced metal skeleton, equipped wi1th a multi-layer labyrinth dust-proof structure. Optimized for extreme working conditions including high-pressure pulsation, heavy load impact, continuous high oil temperature and large shaft runout, it features excellent extrusion resistance, deformation resistance and medium corrosion resistance against hydraulic oil, heavy-duty gear oil and weak corrosive media. The self-adaptive constant-pressure lip dynamically compensates shaft eccentricity, wear gaps and assembly deviations to eliminate micro-leakage under high pressure.
