FXJ475 Replacement Piston For Hydraulic Breaker OEM Customization Service
FXJ475 Replacement Piston For Hydraulic Breaker OEM Customization Service


- High-grade CrNiMo alloy material, better toughness and impact resistance than ordinary CrMo alloy, can withstand 20-22Mpa ultra-high working pressure without fracture.
- Integral quenching and tempering + surface nitriding treatment, uniform hardness distribution (HRC 60-64), strong anti-fatigue and anti-corrosion performance, long service life.
- Precision CNC grinding process, micron-level dimensional accuracy, smooth surface, low friction coefficient, reducing mutual wear with the cylinder.
- Special structural design, optimized stress distribution, effectively reducing the impact force on the piston during high-frequency striking, avoiding deformation.
- 100% full inspection before shipment, including hardness test, impact test, dimensional test, ensuring each piston meets the standard.
- Large stock available, fast delivery; supports small batch trial orders and bulk OEM customization, flexible to meet customer needs.


1.Q1: What is the difference between FXJ475 piston and FXJ375 piston?
A1: FXJ475 is designed for 45-60 ton excavators and large hydraulic breakers, adopting CrNiMo alloy; FXJ375 is for 28-42 ton excavators, adopting CrMo alloy. FXJ475 has higher toughness, impact resistance and longer service life
2.Q2: Can FXJ475 piston be used in high-altitude or high-temperature mining scenarios?
A2: Yes, FXJ475 piston has excellent high-temperature resistance and low-temperature adaptability, which can work stably in high-altitude, high-temperature and other harsh environments without performance degradatioQ3: Do you provide samples of FXJ475 piston? How long does it take to deliver samples?
