Precision-engineered replacement parts to extend the life and performance of your hydraulic breakers.
As a leading hydraulic breaker parts manufacturer, we specialize in producing high-precision, durable thrust bushes, front covers, and lower/upper bushings. These components are critical for maintaining the structural integrity, alignment, and impact efficiency of hydraulic breakers across various models and brands. Whether you operate in mining, demolition, or construction, our parts ensure reduced downtime, enhanced stability, and cost-effective performance .
The thrust bush, front cover, and lower/upper bushings form the core support and alignment system within a hydraulic breaker. These components absorb intense vibrational shocks, maintain tool positioning, and protect the main body from wear.
Our product range includes:
Thrust Bush: Acts as a shock-absorbing buffer between the breaker body and the excavator, reducing stress transmission.
Front Cover: Protects internal components from debris and impacts while securing the tool bushing and chisel.
Lower & Upper Bushing: Ensures precise guide alignment for the piston and chisel, minimizing friction and wear.
All parts are OEM-compatible and manufactured to meet international standards, including CE certification . They are widely used in breakers from brands like Furukawa, NPK, Atlas Copco, Rammer, Montabert, Toku, and MSB .
Technical Features & Design Advantages
- Superior Material & Heat Treatment
High-Carbon Chromium Steel: Components like the thrust bush and bushings are forged from high-strength, wear-resistant alloy steel.
Precision Machining & Hardening: Parts undergo computerized numerical control (CNC) machining and heat treatment processes (e.g., quenching and tempering) to achieve optimal hardness (e.g., HRC 45-55) and toughness . This extends service life under high-cycle fatigue loads.
- Precision Engineering for Optimal Performance
Tight Tolerance Control: Bushings and thrust bushes are machined to exact OEM specifications (e.g., H7/g6 fit) to ensure seamless integration with breaker models .
Smooth Surface Finish: Critical contact surfaces are ground and polished to reduce friction with mating components (e.g., pistons and chisels), preventing premature wear and maintaining impact energy transfer.
- Robust Sealing & Corrosion Protection
Integrated Seal Grooves: Front covers and bushings are designed with precision-cut grooves for O-rings and seal kits, preventing hydraulic oil leakage and contamination ingress .
Anti-Corrosion Coatings: Parts are treated with phosphate or zinc coatings to resist rust and corrosion in harsh environments (e.g., mining or coastal sites).
- Interchangeability & Customization
Direct OEM Replacement: Our thrust bushes, front covers, and bushings are engineered to match original design specifications, ensuring easy installation without modifications.
Customizable Dimensions: We offer tailored solutions based on technical drawings or samples, supporting bespoke requirements for unique breaker models .
Key Benefits for Your Operations
Extended Breaker Lifespan: Precision-fit components reduce stress on the main body, lowering the risk of catastrophic failures.
Enhanced Breaking Efficiency: Properly aligned bushings and front covers maintain optimal energy transfer, ensuring consistent impact force and faster project completion.
Reduced Maintenance Costs: Durable materials and wear-resistant designs minimize frequent replacements, cutting long-term operating expenses.
Global Compliance: Our manufacturing processes adhere to ISO9001 and CE standards, guaranteeing reliability for international markets .
