Product Overview
This high-performance accumulator diaphragm and piston cup seal is custom developed for Atlas Copco SBC610 medium-duty hydraulic rock breaker, a classic SBC series hydraulic hammer matched for 3–9 ton excavators, widely used in municipal demolition, stone quarry and road construction hydraulic systems. The product includes nitrogen accumulator energy storage diaphragm and hydraulic reciprocating piston cup seal, fully supporting complete overhaul and routine maintenance of SBC610 hydraulic breaker.
Adopting fabric-reinforced NBR nitrile rubber and high-wear PU polyurethane as core raw materials, this diaphragm & cup seal features outstanding nitrogen penetration resistance, high-frequency impact resistance, wear resistance and anti-fatigue aging performance, serving as a reliable direct replacement for original Atlas Copco OEM sealing spare parts. It thoroughly solves common faults such as accumulator nitrogen leakage, cylinder internal oil leakage and system impact pressure attenuation, greatly extending the service life of SBC610 breaker under long continuous striking, severe vibration and dusty harsh construction conditions.

Key Selling Points
1. 100% OEM Dimensional Matching, Direct Installation Without Modification
Fully consistent with original Atlas Copco SBC610 breaker in outline, thickness and installation size, matched with OEM part number 1470604. No cutting, grinding or secondary processing required. Suitable for daily maintenance, field overhaul and emergency site repair, effectively shorten equipment downtime and reduce manual maintenance costs.
2. Composite High-Grade Sealing Materials, Stable Sealing in Full Temperature Range
The energy storage diaphragm adopts thick fabric-reinforced NBR base material, with excellent tear resistance and elastic recovery, no cracking after tens of thousands of cyclic high-frequency impacts; the piston cup seal uses high-hardness cast PU material with strong anti-extrusion and anti-wear performance. The material resists nitrogen aging, hydraulic oil corrosion and permanent deformation, maintaining stable sealing elasticity continuously from -40°C alpine mining to 120°C high-temperature underground construction environment.
3. High Pressure & Anti-Vibration Design, Eliminate Pressure Loss & Oil/Gas Leakage
All sealing components pass strict 24MPa high-pressure durability and long-cycle impact simulation tests. The curved bowl-shaped structure fits the inner cavity of the accumulator perfectly, completely avoids nitrogen leakage of the energy storage chamber and internal oil seepage of the striking cylinder, stabilizes hydraulic impact pressure, and ensures constant striking force of SBC610 breaker under heavy rock breaking, continuous impact and strong vibration working conditions.
4. Special Molded Design for SBC610, Easy Inventory & Maintenance
Independently molded targeting the accumulator and piston sealing positions of SBC610 hydraulic hammer, single-piece independent vacuum packaging, convenient spare parts classification and inventory management, effectively shorten the overall repair cycle and reduce daily operation and maintenance costs of excavator attachments.
5. Multi-Round Factory Strict Inspection, Performance Reaches OEM Standard
Each set of diaphragm and cup seal undergoes air tightness leakage test, high-pressure durability test and cyclic impact aging test before delivery. All performance indicators meet the original factory technical standards, providing long-term stable operation guarantee for construction machinery hydraulic breaking equipment.
6. Wide Application Coverage for Multiple Construction Scenarios
Specially matched for Atlas Copco SBC610 hydraulic breaker, widely applied in various medium-duty construction and mining projects:
• Municipal Demolition: Concrete road breaking, old building dismantling, pipeline foundation trenching
• Stone Quarrying: Medium-hard rock excavation, stone shaping, mine surface stripping
• Road & Bridge Engineering: Mountain side slope trimming, subgrade hard rock crushing, small tunnel excavation
• Water Conservancy Works: Canal rock excavation, dam foundation trimming
• Emergency Rescue: Frozen soil breaking, small rock splitting, landslide hazard cleanup
