380B Secondary Lateral Damper

Hydraulic shock absorber components engineered in our advanced facility undergo 100 percent type testing to eliminate potential field failures under demanding operations.

1. Symmetric Damping Force Characteristics: At a nominal speed of 0.01 meters per second, the system yields a balanced damping force of 4.35 kN in both the extension and compression directions. For true operational speed limits of 0.150 meters per second, the force scales perfectly to a controlled 15.90 kN.

2. Strict Asymmetry Rate Limit: The asymmetry variance between the extension and compression forces is strictly maintained within 10 percent or lower. This factor is calculated by getting the absolute difference between the extension and compression forces, dividing it by their total combined sum, and multiplying by 100 percent.

3. Optimized Dynamic Stiffness: Tested under a constant frequency of 7 Hz and a physical amplitude of plus or minus 1 mm, the dynamic stiffness is held firmly between a minimum of 13 MN/m and a maximum of 16 MN/m.

4. Extreme Thermal Tolerance: Operates efficiently from severe cold at minus 40 degrees Celsius up to hot ambient limits of plus 70 degrees Celsius, with a local temperature margin of plus or minus 2 degrees. All rubber joints, flexible dust bellows, and internal oil seals retain complete elasticity without any cracking or fluid leaks.

5. High-Frequency Fatigue Endurance: Successfully achieves full clearance over 4,000,000 continuous testing cycles at a frequency of 2 Hz and a stroke amplitude of plus or minus 3 mm, ensuring the ultimate damping force degradation remains safely below 10 percent.

2. Urban Mass Transit: High-end damping components custom-fitted for regional Metros, Subways, and Light Rail networks.

3. Conventional Railway Systems: Ultra-durable shock absorbing components built for heavy Locomotives, Passenger Coaches, and Freight Wagons.

4. Track Maintenance Machinery: Industrial-grade heavy-duty dampers tailored for large-scale railway construction and tamping fleets.

1. Can your railway hydraulic shock absorber models be customized for unique rolling stock projects?

Yes, we provide two separate paths for custom manufacturing. We support customized production according to your unique engineering drawings, or we can engage in standardized re-engineering for existing train fleets.

2. What certifications does your suspension hydraulics testing lab possess to guarantee product safety?

Our state-of-the-art railway damper laboratory holds dual CNAS and CMA national certifications. Our facility stands at the forefront of testing technology in China, benchmarking directly with top institutions like the China Academy of Railway Sciences and Southwest Jiaotong University.

3. What is your enterprise's historical milestone in the Chinese high-speed train sector?

We are proud to be the very first private enterprise in China to successfully obtain the official EMU Component Certification for high-speed passenger trains operating at speeds above 300 km/h, validating our top-tier engineering authority.

4. How competitive is your hydraulic shock absorber pricing compared to global brands?

By maintaining full control over our manufacturing facility and local raw material supply chain in China, we offer superior pricing advantages. We utilize a flexible tiered pricing structure, which means long-term cooperation and framework agreements unlock deeper contract discounts.

5. Do you provide both brand-new manufacturing and maintenance overhaul programs?

Yes, we provide full-lifecycle support. We offer brand-new product manufacturing alongside professional maintenance and overhaul services. The overhauled dampers pass through the exact same CNAS and CMA test matrices, guaranteeing that their performance and quality match original units while reducing operator costs.

6. Are your suspension hydraulics components prepared for next-generation faster lines?

Yes, we are actively designing the future of rail transit. Showing our deep technological capability, our custom dampers engineered for the CR450 project—which is currently China's fastest next-generation high-speed rail platform—have already entered advanced experimental track testing phases.

7. What scope of warranty protection and after-sales support do you offer to global purchasers?

Every product shipment includes trace-monitored factory warranty documents and complete type-test data summaries. We provide immediate remote technical support for installation, and can set up specialized localized service protocols for high-volume fleet operators.

8. Is it possible for a transit authority to order a small-scale batch for local field trials?

Yes, we understand that risk management is vital for railway engineers. We welcome small-batch trial orders, allowing you to install our dampers on your local test lines, analyze real-time track data, and verify our stable product quality firsthand before entering large procurement contracts.

9. What types of global partnerships is your factory looking to establish?

We are actively seeking win-win alliances with international railway component distributors, state railway operators, and urban metro authorities. We are also fully open to joint research and development projects to co-create specialized dampers for unique local rolling stock platforms.

10. Can international engineering auditors arrange a physical visit to your production facility?

We warmly welcome overseas engineering delegations, transport ministries, and technical distributors to visit our production facilities. You can inspect our automated assembly lines and see our CNAS and CMA dual-certified laboratory in motion, ensuring complete confidence in our volume supply capacity.

Suspension hydraulics equipment is the backbone of operational safety on high-speed lines, and our facility takes this responsibility seriously. As an experienced and fully certified high-speed rail supplier in China, our team delivers impeccable manufacturing quality, continuous volume supply, and absolute after-sales accountability.
