High-Reliability Hydraulic Breaker Accumulators specifically designed for Furukawa HB series (HB15G, HB20G, HB30G). As a critical energy storage and damping device, our accumulator assemblies are engineered to absorb the high-frequency shock pulses generated during rock breaking. By stabilizing hydraulic pressure, they prevent premature fatigue of the excavator’s hydraulic pump and internal breaker valves, ensuring maximum operational ROI.
Ensure peak performance and protect your hydraulic breakers (models HB15G, HB20G, HB30G) with our premium Cylinder Accumulator Assembly.
Forged 35CrMo Steel Shell: Our accumulator bodies are manufactured using heavy-duty forged alloy steel, capable of sustaining continuous pressure cycles up to 350 bar without structural failure.
Premium Japanese Diaphragms: We use high-grade diaphragms characterized by superior gas impermeability and oil resistance, extending the N2 pressure retention time by 40% compared to standard kits.
Precision Valve Sealing: Every assembly undergoes a 24-hour high-pressure leak test before shipment to guarantee “Ready-to-Install” performance.
Why is my breaker striking weakly? A damaged accumulator diaphragm or incorrect Nitrogen (N2) pressure is the most common cause. We provide pre-charged N2 options and specialized Nitrogen Charging Kits for all HB series models.

HB30G Rock breaker accumulator
This crucial component acts as a reliable energy storage and dampening device, engineered to stabilize hydraulic pressure, absorb intense shock pulses, and minimize damaging vibrations during demanding rock-breaking and demolition operations. By ensuring smoother hydraulic system functionality, it significantly reduces stress on the breaker’s internal circuits, helps prevent oil leaks, and is proven to extend the operational lifespan of your machinery.
Ideal for heavy-duty applications in mining, quarrying, and large-scale construction projects, our accumulator maintains consistent power output under extreme loads, thereby boosting productivity and reducing costly downtime.
As a trusted supplier and manufacturer, we provide OEM-compatible accumulator assemblies that are precision-engineered with robust materials and undergo rigorous testing for guaranteed reliability, durability, and safety.
