Productum Overview

Hoc accumulatōrium robustum diaphragma & piston cup repair kit is specially developed for JAB RB38 / RB48 / RB68 hydraulic rock breakers, widely matched on mini & medium excavator demolition hammers. The package contains complete energy storage diaphragm, piston cup, matching Anuli O , gaskets and backup sealing rings for full accumulator overhaul.

Adopted imported reinforced HNBR and FKM fluororubber composite material, the kit delivers outstanding oil resistance, anti-fatigue performance, high-frequency impact resistance and wide temperature adaptability. It perfectly replaces original JAB rubber parts, solves typical faults including nitrogen leakage, insufficient impact force, breaker power attenuation and overheating, and greatly extends the service life of the breaker under long-term stone crushing, demolition heavy-load working conditions.

Claves Venditionis Puncta

1. 100% Exact OEM Replacement. Fully dimensional matched with original JAB RB38/RB48/RB68 breaker accumulator parts, consistent with OEM part numbers JAB-RB38, JAB-RB48, JAB-RB68, 3088621/3088622/3088623. Direct installation without cutting, grinding or modification.

2. Premium Reinforced Composite Sealing Material. Core diaphragm and piston cup adopt fabric-reinforced HNBR & FKM dual composite process, anti-aging, hydraulic oil corrosion resistant, ultra-high tear resistance, stable elastic recovery under -35°C to 130°C complex working environment.

3. Zero Nitrogen Leakage & Stable Impact Output. All rubber parts pass 130 MPa ultra-high pressure fatigue impact test, effectively isolate hydraulic oil and nitrogen chamber, eliminate internal air leakage and pressure loss, maintain consistent breaker impact frequency and breaking force, avoid equipment power drop and oil temperature rise.

4. Completa seta de renovatio integral. Integrat omnes accessorii de sigillatio rubber necessarii pro maintenance completa accumulatoris. Unum set sufficit ad omnes necessitates reparationis, breviat tempus maintenance in loco et minuit costum operationis apparatus & substitutionis partium.

5. Strictum controlum qualitatis in fabrica. Omnis kit diaphragmatis & cupae pistonis subicitur testibus airtightness, fatigationis impactus alti frequentialis, et aetationis temperaturarum altarum & bassarum antequam mittatur, plene satisfacit standardibus fabricationis OEM, et certificat operationem stabilem longi temporis in locis constructionis asperis.

6. Lata applicatio. Aptus est pro frangitoribus hydraulicis petrarum JAB RB38/RB48/RB68, quae montantur in pluribus apparatus constructionis graviorum:

• Excavatoribus mediis 6–18 ton (Sany, Liugong, Sunward, Lovol, XCMG) • Martellis hydraulicis mobilibus pro demolitione • Machinis pro concussione lapidum in lapidicis • Apparatus pro demolitione viarum & constructione municipalis • Systemate accumulationis energiae nitrogenis pro frangitoribus hydraulicis • Machinis constructionis mobilibus gravioribus pro impactu
