This high-performance accumulator diaphragm (cup membrane) is specially developed for Furukawa HB1G hydraulic rock breakers. It serves as the core pressure-isolating component of the breaker accumulator, separating nitrogen gas and hydraulic oil to stabilize impact energy output. Manufactured with imported high-strength HNBR + reinforced PU composite material, the diaphragm delivers outstanding oil resistance, anti-fatigue, anti-tear and high-pressure vibration resistance. It perfectly replaces original Furukawa OEM diaphragm, solves common faults including insufficient striking force, oil-gas mixing, breaker overheating and frequent pressure drop, and greatly extends breaker service life under continuous heavy crushing operation.

Fully matched with original Furukawa HB1G breaker accumulator, corresponds to OEM part number HB1G-70511. Standard size, no cutting or modification required for direct installation, consistent assembly tolerance with genuine spare parts.
Adopts imported HNBR base rubber with PU fiber reinforcement layer, effectively resisting hydraulic oil corrosion, high-frequency vibration and repeated stretching. Stable performance under -30°C to 120°C long-time working environment, greatly reduce tearing and aging failure.
Pass strict 23MPa high-frequency fatigue impact testing. Effectively isolate nitrogen and hydraulic oil, avoid gas-oil mixing inside accumulator, maintain stable internal pressure of the breaker, guarantee continuous and powerful striking force without power attenuation.
Integrated thickened edge molding process, uniform wall thickness, superior anti-stretching and anti-tear performance. Compared with ordinary single-layer rubber diaphragms, service life increased by over 60%, cut down frequent replacement downtime and maintenance cost.
Each diaphragm undergoes air tightness, high-pressure fatigue and thermal aging tests before delivery, fully meets OEM production standards, stable and reliable for long-term construction site heavy load use.
Suitable for Furukawa HB1G hydraulic breakers equipped on multiple engineering equipment:
