CAT piston 415-4315 plays a key role in the engine combustion chamber. It compresses the combustible mixture through reciprocating motion, cooperates with spark plugs or injectors to achieve combustion work, and converts thermal energy into mechanical energy. Its sealing and wear resistance directly affect engine power output and fuel efficiency. Made of high-strength aluminum alloy or forged steel, it is formed by precision casting and machining, with the top design adapted to different combustion systems to ensure full combustion.
The outer circle of the piston is honed, and the fit clearance with the cylinder liner is controlled at 0.03-0.05mm. The piston ring groove precision reaches IT6 level, ensuring sealing performance and reducing gas leakage and oil consumption. The surface is treated with anodizing or molybdenum spraying, with hardness up to HV120-150, high temperature resistance up to 350℃, compatible with CAT 330D, 349D, C13B and other series engines, and can withstand burst pressure above 180bar.
Original piston 415-4315 strictly follows CAT manufacturing specifications, with raw materials and processes fully matching the original engine, suitable for heavy-duty operations with extremely high performance requirements; Aftermarket pistons pass 1000-hour bench tests, with key dimensions and sealing performance up to standard, priced at 60%-70% of the original, meeting the replacement needs of budget-conscious customers.
As a professional supplier, Ningbo Qiuning Trading Co., Ltd. provides material certificates and dimension inspection reports for each batch of pistons, with inventory covering mainstream models, supporting global delivery within 72 hours, and offering guidance on installation gap adjustment.
