1,well-fit:The piston model 297-7753 is designed for the excavator E320C engine and precisely matches the engine cylinder size. Its circumference, height and other dimensions are strictly designed to fit closely with the cylinder wall, ensuring that the piston can smoothly reciprocate in the cylinder and avoid engine failure caused by size discrepancies.
2,Excellent wear resistance:Considering the high working intensity of the excavator engine, the piston 297-7753 is made of high-quality wear-resistant materials. 
3,High structural strength:When the excavator is working, the engine needs to bear greater load and impact force. The piston 297-7753 is structurally designed to withstand these pressures.
4,Contribute to efficient combustion:The top shape and design of the piston have a great influence on the combustion efficiency of the fuel in the combustion chamber. The top design of the 297-7753 piston facilitates the full mixing of fuel and air, allowing the fuel to burn more evenly in the combustion chamber.
