This heavy-duty accumulator piston cup & diaphragma repair kit is specially developed for MSB MS500 / MS520 hydraulic rock breakers, widely matched with 6–12 ton excavators for demolition, mining and road construction works. The set contains complete energy storage leather cups, main diaphragms, auxiliary Anuli O and wear-resistant backing rings for full accumulator overhaul.
Adopted imported modified NBR and high-performance FKM fluororubber with reinforced fiber vulcanization process; parts feature outstanding oil resistance, low-temperature flexibility, anti-fatigue properties, and high-frequency impact resistance. Perfectly replaces original MSB diaphragm and piston cup parts; resolves common faults such as nitrogen leakage, impact power attenuation, diaphragm cracking, and frequent replacement—greatly extending breaker continuous operation life under prolonged heavy-impact working conditions.

Fully dimensionally consistent with original MSB MS500/MS520 breaker parts, matching OEM part numbers MSB-500-DIA, MSB-520-CUP and 3070405012. No cutting, grinding or modification required, plug-and-play installation for quick maintenance.
Core piston cup and diaphragm adopt fiber-reinforced FKM composite rubber with secondary high-temperature vulcanization. Excellent hydraulic oil corrosion resistance, low-temperature non-hardening, anti-aging, stable elastic performance under -30°C to 120°C wide temperature range.
All components pass 26 MPa ultra-high pressure fatigue test, withstand thousands of high-frequency reciprocating deformation per minute without cracking, delamination or permanent deformation. Effectively isolate nitrogen chamber and hydraulic oil circuit, eliminate internal nitrogen leakage and external oil seepage, maintain stable striking force of the breaker.
Integrat omnes partes in leather cup, diafragma et accessoria sigillandi congruentia quae ad plenam manutenationem accumulatoris requiruntur. Partes de repertorio completas tempus secundarium emptionis minuunt, tempus inoperationis machinarum breviorem faciunt et pretium totale manutenationis machinarum constructionis deducunt.
Omnis kit finitus ante expeditionem subicitur experimentis hermeticitatis aeris, rupturae altae pressionis, aetatis et fatigationis impactionis; omnino normas productionis OEM implet et performatio longa et stabilis in locis constructionis asperis garantitur.
Ad usum frangendorum hydraulicorum MSB MS500 / MS520 montatorum super variis machinis technicis:
