860535021 pistone for XCMG XP225H single drum roller

Short Description:

860535021 Piston is a core power transmission component for XCMG XS225H single-drum roller engine. As the key moving part of the engine combustion chamber, it cooperates with crankshaft and connecting rod components to complete air intake, compression, power and exhaust strokes. It converts combustion pressure into mechanical power, providing stable and continuous power output for the roller’s walking and compaction operations, and is the core source of engine power generation.

advantages

Adopts high-strength heat-resistant aluminum alloy for integral forging forming, with high structural density, excellent high-temperature and pressure resistance, no deformation under long-term combustion impact.
Precision machining of piston skirt and ring groove with strict tolerance control, ensuring perfect fit with piston ring and cylinder liner, effectively reducing air leakage and oil burning phenomena.
Optimized surface anti-wear treatment, low friction coefficient, good running-in performance, reducing cylinder wall wear and lowering engine operating resistance.
Excellent structural fatigue resistance, adapting to high-frequency cyclic reciprocating operation of engine, stable performance and long service life.
Reasonable thermal expansion design, effectively controlling thermal deformation during high-temperature operation, maintaining stable cylinder tightness and power consistency.

maintenance & replacement tips

Regularly check engine power and exhaust status to judge piston working condition and avoid abnormal wear and carbon deposition.
Use qualified lubricating oil and fuel to prevent inferior oil products from causing piston scuffing and ablation damage.
Ensure good heat dissipation of the engine to avoid excessive temperature leading to piston thermal deformation and cylinder pulling failure.
Avoid long-term overload operation and violent acceleration to reduce instantaneous impact load on the piston.
