1. Main oil seal of the piston rod (polyurethane U-ring): Core high-pressure seal, preventing the leakage of high-pressure hydraulic oil from the piston rod of the lifting cylinder;
2. Bidirectional sealing ring + support ring: Oil seals the inside and outside of the cylinder piston, isolating the oil pressure in the rod chamber and the no-rod chamber, ensuring the lifting thrust;
3. Dust ring (dust scraping ring): Installed on the outer side of the cylinder head, it scrapes away sand, gravel, and mud from the piston rod, protecting the main oil seal from being scratched by foreign objects;
4. O-ring, gasket, retaining ring, buffer ring: Components for static sealing at the cylinder cover base, oil ports, and hinge joints;
5. Wear-resistant guide belt: Reduces dry friction between the piston rod and the cylinder cover, as well as between the piston and the cylinder barrel.
