380B Primary Vertical Damper

Suspension hydraulics technology dictates the safety and comfort of modern rail transit. The LBR-G70SX001 model is a dual-cycle anti-hunting damper designed specifically for the CRH380B/C series bogies.

1. Model Designation: LBR-G70SX001

2. Application Platform: CRH380B/C High-Speed Trains with LMB Tread

3. Nominal Weight: 25 kg with a tolerance of plus or minus 5 percent

4. Painting Specification: Surface color RAL7043 Dark Grey with a dry film thickness of 60 micrometers or more, achieving Class 1 adhesion under ISO 16276-2.

5. Salt Spray Resistance: Evaluated per ISO 9227:2012, ensuring no red corrosion on plated surfaces and a paint rating of 7/6Sc or higher per GB/T 6461-2002.

1. Can your railway dampers shock absorbers be customized for specific bogie configurations?

Yes, absolutely. We offer two business tracks: Customized OEM Production (manufacturing according to your unique drawing parameters) and Standardized Re-engineering for existing rolling stock platforms.

2. What credentials does your testing laboratory hold to ensure suspension hydraulics quality?

Our state-of-the-art high-speed train damper laboratory holds both CNAS (China National Accreditation Service) and CMA (China Inspection Body and Laboratory Mandatory Approval) certifications. In terms of testing precision and capability, our lab stands at the absolute forefront in China, perfectly benchmarking with top-tier national institutes like the China Academy of Railway Sciences (CARS) and Southwest Jiaotong University.

3. What is your company’s historical background in the Chinese high-speed rail market?

We are proud to be the very first private enterprise in China to obtain the official EMU (Electric Multiple Unit) Component Certification for trains operating at speeds above 300 km/h. This breaks the monopoly and validates our top-tier engineering status.

4. How are your dampers shock absorbers priced compared to OEM international brands?

Because we control the entire supply chain and operate a highly efficient localized manufacturing base in China, our pricing is significantly more competitive. We offer a tiered pricing structure: the longer the cooperation, the more favorable the contract discounts we can extend to our partners.

5. Do you offer both brand-new manufacturing and maintenance/overhaul services?

Yes. To help railway operators effectively reduce lifecycle and operational costs, we offer a dual service model: New-build manufacturing and professional maintenance/overhaul services. The overhauled dampers undergo the exact same CNAS/CMA testing matrix to ensure their performance and quality are completely identical to brand-new units.

6. Are your dampers shock absorbers compatible with the next-generation faster trains?

Yes. Showcasing our deep engineering expertise, our dampers designed for the CR450 platform—which is currently China’s fastest next-generation high-speed train project—have successfully entered the advanced experimental track testing phase.

7. What kind of warranty and after-sales support do you provide for international clients?

Every single damper shipped comes with a comprehensive factory warranty and traceable type-test data reports. We provide full remote technical support for installation, and for long-term fleet partners, we can establish localized service frameworks.

8. Can we place a small-scale trial order before committing to a mass procurement contract?

Yes. We highly value risk management for railway operators. We welcome small-batch trial orders so you can install our dampers on a test train line, verify the data against your local conditions, and experience our real-world quality firsthand.

9. Who are your ideal cooperative partners globally?

We are actively looking to build win-win partnerships with regional railway components distributors/agents, national railway operating authorities, and urban metro/subway transit operators. We are also open to joint R&D projects to co-develop custom dampers for localized rolling stock.

10. Is it possible to visit your manufacturing facility and advanced laboratory?

We warmly welcome overseas delegations, transit authorities, and engineering auditors to visit our factory. You can witness our automated production lines and see our CNAS/CMA dual-certified laboratory in action, giving you complete peace of mind regarding our supply stability and technical rigor.
