Engine parts for construction machinery
Construction machinery engine components include the crankshaft, piston, piston rings, bearings, gaskets, and cylinder head, ensuring stable engine operation. These parts are made of hardened alloy steel, heat-resistant aluminum, or cast iron with tensile strength from 250 to 800 MPa. Each component is precision machined and heat treated—such as hardening, stress relief, and anti-wear coating—to provide high thermal and fatigue resistance. Dimensional accuracy is controlled within 0.02–0.08 mm for optimal sealing, force transfer, and lubrication.
Components include compression and oil rings to reduce friction, full gaskets to prevent fluid and gas leakage, and bearings supporting axial and radial loads. Modular design and easy installation allow rapid on-site replacement. Surfaces are protected with corrosion-resistant and anti-wear coatings, extending engine life beyond 5000 hours. This structure improves combustion efficiency, reduces fuel consumption, and ensures stable performance in heavy diesel and gasoline engines.
