Box Type 68mm Tool Diameter Hydraulic Breaker Rock Breaker For 4 - 7 Ton

Our company stands out in the industry due to our superior product quality, advanced manufacturing processes, and exceptional customer service. Below is a detailed explanation of our product advantages:

At SEWOOMIC, most of our hydraulic breaker components, such as rod pins, are produced using advanced forging techniques. Forging significantly improves both durability and precision, ensuring our products deliver outstanding performance and longevity in demanding applications. While cold drawing is a more cost-effective process frequently used in the market, it often results in lower-quality products. We only utilize cold drawing for select models (including HB20G, HB30G, and SB121), and even then, we insist on using only the highest-grade materials.

To further enhance functionality and safety, we incorporate additional processes such as chamfering edges and drilling lifting holes—critical steps that many competitors overlook for convenience. These enhancements ensure easier handling and improved safety during installation and use.

For key components like cylinders, we apply CQT (Carburizing Quenching and Tempering) heat treatment, achieving a wear-resistant layer thickness of 1.5–1.7 mm—significantly thicker than the industry standard of 1.1–1.3 mm. This advanced heat treatment process extends product lifespan and optimizes performance, even under heavy-duty conditions.

We also perform precision grinding, a quality control step often omitted by competitors, to guarantee a flawless surface finish and precise dimensions, resulting in smoother operation and reduced wear.

Choose SEWOOMIC hydraulic breaker parts for unmatched durability, superior wear resistance, and exceptional quality in every detail.

We exclusively use high-grade materials, such as:

• 20CrMo (forged parts for medium cylinders, superior to cast or scrap materials used by others).

• GCr15/20Cr2Ni4A/616V for pistons, offering exceptional strength and wear resistance.

• Q355 (22mm thickness for shells), compared to the cheaper Q235 commonly used by competitors.

Cost Comparison Example:

• Piston Material:

  • Our 20Cr2Ni4A with CQT treatment costs 2,793 RMB (approx. 300 USD more) compared to standard 42CrMo with QT treatment (665 RMB).

• Wear Layer:

  • Our 20CrMo with CQT achieves 1.8-2.0mm wear layer (630 RMB), while competitors typically offer 1.1-1.3mm (252 RMB).

We possess strong R&D capabilities, allowing us to customize products according to client requirements. This flexibility ensures our solutions meet diverse industrial needs.

• 1-Year Warranty: Backed by a professional after-sales team.

• Rapid Claim Resolution: We strive to address issues within 8 hours, minimizing downtime for clients.

We welcome clients to visit our facilities to witness our advanced processes and quality control measures firsthand. Our team provides comprehensive guidance during these visits to showcase our manufacturing excellence.

Our products may come at a higher price point, but the investment is justified by:

• Unmatched durability (forging, CQT treatment).

• Superior materials (high-grade alloys).

• Precision engineering (grinding, chamfering).

• Reliable support (customization, fast after-sales service).

Choose us for products that deliver long-term value and performance.
