This premium accumulator diaphragma & piston cup repair kit is specially developed for AJCE F-series hydraulic rock breakers AJCE 250F and 280F, widely installed on medium-sized excavators for demolition, rock crushing and mining works. It includes complete nitrogen isolation diaphragm, integral piston cup, auxiliary Anuli O and gaskets for full accumulator overhaul.
Manufactured with imported high-performance modified NBR and reinforced FKM fluororubber, the kit features outstanding oil resistance, high-frequency fatigue resistance, wide temperature adaptability and anti-aging performance. It perfectly replaces original AJCE rubber parts, solves typical failures including nitrogen leakage, impact force drop, breaker overheating and pressure instability, and greatly extends the service life of breakers under long-term heavy impact operation.

Plene dimensione congruente cum originalibus fractoribus hydraulicis AJCE 250F et 280F, congruens cum numeris partium OEM AJCE-250F-DIA, AJCE-280F-CUP et BRK-250280F01. Nulla sectio, limatio aut modificatio requiritur pro installatione directa unius gradus.
Diafragma centrale et cupa pistonicia ex caoutchouco FKM importato cum strato intermedio renforti textili utuntur, efficaciter resistentes corrosioni olei hydraulici, extensioni alti frequentiae et deformationi impactus repetitae. Performantia elastica stabilis servatur ab -30°C usque ad 120°C, nullum induratio, fissura aut deformatio permanens sub operatione continua.
Omnes partes per rigorosam probationem cycli fatigationis ad altam pressionem 28 MPa transierunt. Securum isolant cameram nitrogenii et circuitum olei hydraulici, eliminant fugam nitrogenii internam et percolationem olei externam, conservant energiam impactus constantem et evitant attenuationem potentiae fractoris, supercaldam et frequentem repletionem nitrogenii.
Contains all sealing consumables required for full accumulator maintenance of AJCE 250F/280F. Integrated diaphragm, piston cup and matching auxiliary seals are packed together, greatly shortening on-site repair time and reducing equipment maintenance cost and downtime loss.
Each batch of diaphragm and piston cup undergoes air tightness, high-pressure fatigue and thermal aging tests before delivery, fully meeting AJCE original equipment manufacturing standards, ensuring long-term stable operation under harsh construction conditions.
Suitable for AJCE 250F & 280F hydraulic rock breakers equipped on multiple medium-duty construction machinery:
