Q6: What is the service life and maintenance?

A: Vulcanized rubber and steel, properly installed and inspected, deliver decades of service -- no lubrication or moving parts; periodic inspection is the standard practice.

Q7: How do I select the right LRB size?

A: Sizing follows vertical load, horizontal displacement, and seismic demand -- our engineers calculate plan dimensions, layer count, and lead core diameter from your project data.

Key features

Lead core energy dissipation and seismic isolation with stable vertical bearing capacity, consume seismic energy and protect building structures.

Solve poor shock resistance, large displacement and structural damage of ordinary bearings. Self-energy dissipation and reset reduce vibration and deformation.

High damping coefficient and excellent energy consumption, strong bearing capacity and high reset accuracy, anti-aging and anti-fatigue with stable long-term performance.

Suitable for bridges, viaducts and buildings in high seismic intensity areas, improve seismic grade and reduce post-disaster maintenance costs.

Better seismic energy dissipation and automatic reset function, higher stability than ordinary rubber bearings, more suitable for severe seismic working conditions.

AI-Powered supplier vetting

SummaryThe supplier is identified as a factory and limited company with associated companies, offering a broad range of bridge, rubber, sealing, and customized products. It reports 10 production lines, defined product output, six to ten quality-control staff, and export experience of 10 years, with exports representing 41%–50% of total sales. The supplier provides extensive customization and ODM services and reports new products during the past year. However, no supplier-management-system certification is reported, and its service-capability procedures lack written records for assessment and corrective/preventive actions. Complaint handling has a clear procedure with follow-up records. The supplier has no overseas warehouse, showroom, agent or branch, or offline trade-show participation. Financial credibility cannot be assessed from the available non-financial information.

Supplier typeThe supplier is explicitly classified as a factory and limited company, with associated companies and manufacturing as the industry of those companies. This supports direct manufacturing status rather than a trading-only profile.

CertificationsThe supplier-management-system certification field is explicitly reported as NIL. No certification evidence is provided for this field, indicating a stated lack of supplier-management-system certification.

After-Sales capabilityThe supplier has a clear customer-complaint handling procedure with follow-up records, which is positive evidence for after-sales issue management. However, assessment and corrective/preventive-action procedures have no records, so the service system is only partially documented.

R&D capabilityThe supplier reports new products during the past year and provides ODM services, indicating active product-development capability. However, it reports no available SDK, which limits evidence of software-development or integration capability.

Production capacityThe supplier is a factory operating 10 production lines, with six to ten quality-control staff and stated output across rubber culvert balloons, seismic isolation bearings, waterstops, and expansion joints. It also reports inspection instructions that are uniformly followed, supporting established production and quality-control operations.

Customization capabilityThe supplier explicitly offers customization from samples and designs, full, minor, and flexible customization, including made-to-order products with complex profiles and different materials. It also provides ODM services, demonstrating broad customization coverage.

Client casesThe supplier states that it provides OEM services for well-known brands, which is direct evidence of at least one customer-case category. No customer names, project details, volumes, or independently verifiable case documentation are provided.

Product Q&A

Q:Q1: How is LRB different from an HDR bearing?

A: LRB uses a lead plug for damping; HDR builds damping into the rubber compound itself -- both isolate, but LRB delivers higher damping per unit and is the standard for high-seismic projects.

Q:Q2: How does the lead core absorb earthquake energy?

A: During strong shaking the lead yields plastically -- it deforms permanently and converts seismic energy into heat, so the force never reaches the structure.

Q:Q3: Does the bearing return to position after an earthquake?

A: Yes -- the rubber layers act as a spring and restore the bearing to its original position once the shaking stops, keeping the structure serviceable.

Q:Q4: Can the same bearing serve bridges and buildings?

A: Yes -- size, layer count, and lead core diameter are engineered from the structural load and seismic demand, for highway, railway, and building base isolation.

Q:Q5: How does temperature affect performance?

A: The compound is formulated for stable performance across -40 Celsius to +80 Celsius -- damping and flexibility hold in both cold and hot climates.
