Product Description
Product Features
- Straight-Body Design: Streamlined housing minimizes vibration transfer to the excavator boom and arm, reducing host machine fatigue and extending structural lifespan by up to 20%.
- Hydraulic-Nitrogen Combined System: Integrated nitrogen accumulator chamber amplifies impact energy on each stroke, delivering higher breaking force with lower oil flow consumption compared to pure hydraulic breakers.
- Induction-Hardened Piston: Precision-machined piston with surface hardness HRC 58-62 withstands 100,000+ impact cycles without deformation, ensuring long-term reliability.
- 100mm Premium Chisel: Forged from high-carbon alloy steel with through-hardened treatment, available in pointed (general purpose), flat (surface breaking), pyramidddd (hard rock), and wedge (quarrying) configurations.
- Anti-Blank Firing System: Automatically stops piston impact when no material resistance is detected, protecting both the chisel tip and piston face from destructive metal-to-metal contact.
- Optimized Recoil Damping: Nitrogen chamber absorbs rebound energy, reducing operator fatigue and noise levels by 15% compared to open-type breakers.
- Low Oil Flow Requirement: Only 80-110 L/min needed, reducing fuel consumption of the host excavator by 8-10% during breaking operations.
- Modular Maintenance Design: Simplified internal structure allows chisel and seal kit replacement in under 1 hour with basic hand tools — no special equipment required.
- Grease Lubrication Points: Dedicated grease nipples on chisel bushings ensure easy field maintenance, extending chisel service life to 800-1,200 hours.
🏗️ Applications
- Building Demolition: Breaking reinforced concrete walls, foundations, floor slabs, and bridge decks in urban demolition projects.
- Quarrying & Mining: Secondary breaking of medium-hard rock (limestone, sandstone, shale) after primary blasting in quarries and small-scale mining operations.
- Road Construction & Maintenance: Asphalt pavement removal, concrete road breaking, and trenching in rocky soil conditions.
- Tunnel Engineering: Rock face scaling and profile trimming in small to medium tunnel sections.
- Recycling & Crushing: Breaking concrete debris for reuse as recycled aggregate material at demolition sites.
- Pipeline & Utility Trenching: Breaking rocky ground for water, gas, and fiber optic pipeline installation.
- Dock & Wharf Renovation: Concrete structure breaking in marine environments with salt-resistant chisel options.
⚙️ Manufacturing Process
- Raw Material Selection: High-strength alloy steel (42CrMo) for housing and piston, high-carbon alloy steel for chisel — all materials inspected via spectrometry for composition verification and ultrasonic testing for internal defects.
- Precision Forging: Hot forging at 1,150-1,200°C creates uniform grain flow throughout the housing body, eliminating porosity and maximizing impact resistance.
- CNC Machining: 5-axis CNC centers machine the piston and cylinder bore to tolerance within ±0.01mm, ensuring precise fit and minimal internal leakage.
- Induction Hardening: Piston surface hardened to HRC 58-62 with controlled case depth of 3-5mm; chisel tip hardened to HRC 60-64 for maximum wear resistance.
- Nitrogen Chamber Welding: High-frequency resistance welding creates hermetically sealed nitrogen accumulator with pressure tested to 2× operating pressure.
- Surface Treatment: All external surfaces receive shot blasting + anti-corrosion epoxy coating for long-term protection in harsh environments.
- Assembly: Clean-room assembly with torque-controlled fastener tightening, sealed with imported NOKKKK/Nachi seals and O-rings.
- 100% Factory Testing: Every unit tested for impact force consistency, oil leakage, noise level (≤105 dB at 1m), nitrogen pressure holding, and 500-cycle endurance run before shipping.

FAQ
Q: Is this SB50 breaker compatible with my Doosan DX140LC / Cat 315 / Komatsu PC130?
A: Yes, the SB50 is compatible with most 10-12 ton excavators including Doosan DX140LC/DX150LC, Cat 315/318, Hitachi ZX130/ZX150, Komatsu PC130/PC150, Hyundai R140/R160, and Volvoooo EC140/EC160. Please confirm your excavator's auxiliary oil flow matches 80-110 L/min and operating pressure is 150-170 kgf/cm².
Q: What type of chisel should I use for breaking hard granite?
A: For hard rock like granite, basalt, or quartzite, we recommend the pyramidddd-type chisel, which concentrates impact force on a small contact area for superior penetration. For reinforced concrete demolition, the pointed chisel offers the best balance of penetration and breaking speed. For surface breaking and asphalt removal, the flat chisel provides the widest coverage.
Q: How often should I grease the chisel bushing?
A: Grease the chisel bushing every 4-5 working hours using NLGI #2 lithium-based grease. Proper lubrication extends chisel service life to 800-1,200 hours. In dusty or abrasive conditions, increase greasing frequency to every 2-3 hours.
Q: What is the correct nitrogen pressure for this breaker?
A: The standard nitrogen charging pressure is 8-10 kgf/cm² (0.8-1.0 MPa). Incorrect nitrogen pressure will reduce impact force or cause excessive recoil. We recommend checking nitrogen pressure every 250 working hours.
Q: How do I know if my breaker needs maintenance?
A: Common signs include reduced impact force, increased noise, oil leakage around the chisel bushing, irregular impact rhythm, and visible wear on the chisel tip (tip wear >9mm requires immediate replacement).
