Oil Resistant Reinforced Hydraulic Breaker Diaphragm Fkm Fit Atlas Copco SBC Rock Breaker

1. HNBR Standard Grade: Balanced oil resistance and anti-fatigue performance, cost-effective for daily municipal and medium quarry construction, stable under millions of reciprocating expansions.
2. FKM Viton Heavy-Duty Grade: Superior high temperature hydraulic oil corrosion resistance, suitable for non-stop long-shift hard rock breaking with high oil temperature, anti-aging and long service cycle.
3. TPU Fiber Reinforced Grade: Ultra high tensile and tear strength, ideal for harsh dusty quarry mining sites with severe vibration and heavy impact.
4. Every SBC series diaphragm membrane adopts one-step integrated compression molding process with built-in fiber reinforcement layer. Uniform wall thickness eliminates thin vulnerable areas, allowing the membrane to withstand repeated cyclic expansion and contraction without cracking, deformation or rupture. Precision dimensional control ensures perfect OEM matching with the original accumulator cavity, blocking nitrogen leakage and oil mixing issues completely.

Core Performance Advantages

1. Stable Energy Recovery Efficiency
2. Intact diaphragm maintains standard nitrogen pressure to maximize the breaker’s energy recovery technology, boosting impact energy without extra hydraulic consumption, reducing fuel loss and blank firing abrasion of internal spare parts.
3. Long Service Life Under Heavy Load
4. Composite rubber formula resists hydraulic oil erosion, high temperature aging and frequent impact fatigue, solving common breakdown troubles such as air leakage soft blow and insufficient crushing force on mining sites.
5. Quick On-Site Replacement
6. One-to-one direct replacement without cutting or modification, perfectly matched with SBC series full seal kits for complete machine overhaul, shortening equipment downtime on busy construction and mining sites.
7. Wide Temperature Adaptability
8. Stable working performance between -35℃ and 135℃, applicable to summer high-temperature open-pit mining and winter low-temperature outdoor demolition construction.
9. Widely used in primary rock crushing quarry mining reinforced concrete structure dismantling highway foundation breaking large tunnel excavation and industrial building demolition works. Each batch of diaphragm membrane undergoes nitrogen tightness test reciprocating fatigue cycle test and hydraulic oil soaking aging test to meet original equipment interchange standards.

We keep sufficient stock of all SBC series diaphragm membrane specifications to support small retail repair orders and large bulk wholesale for mining companies demolition contractors and machinery rental firms. Custom diameter thickness and customized rubber formula production service can be supplied for global machinery maintenance factories and spare parts dealers.
