How is the vertical stiffness achieved?

High vertical stiffness is achieved by using thin layers of rubber reinforced by steel shims, allowing the bearing to carry significant axial load.

What is the maximum load capacity?

The bearings can handle capacities of up to 3000 tons.

What is the curing process for the bearings?

Molding each bearing takes 8 to 48 hours depending on size, with the curing phase continuously monitored to ensure uniform curing.

Key features

Lead Core Damping: 90% of isolators feature a lead core that provides damping by deforming plastically during earthquakes.

High Vertical Stiffness: Thin rubber layers reinforced by steel shims ensure high vertical stiffness while allowing lateral movement.

Custom Dimensions: Custom dimensions are available for special applications, ranging from 200 to 1200 mm in diameter.

High Load Capacity: Manufactured capacities of up to 3000 tons for structural support and seismic isolation.

Precision Manufacturing: Shims cut by laser and steel plates machined by CNC for high accuracy and production throughput.

Multiple Certifications: Products hold CCC, CE, and ISO certifications, meeting standards like JT/T4-2004 and BS5400.

Durable Materials: Made from Neoprene or Natural Rubber with high tensile strength and ozone resistance.

Fast Lead Time: Off-season lead time is within 15 workdays, ensuring timely delivery for projects.

AI-Powered supplier vetting

SummaryHaider shows documented customization and product development activity, with products reportedly used in highways, railway bridges, and public buildings. It claims ISO9001:2008 and ISO14001:2004 certification, advanced production and testing equipment, 200 staff, and a professional installation and after-sales team. However, the supplier is also identified as a trading company, and key operational evidence is mixed: no in-stock capacity, overseas warehouse, overseas showroom, overseas agents or branches, or overseas-service countries are reported. Quality assurance and traceability statuses are unknown, while the stated quantity and size of quality-control test equipment is zero. Financial-capacity entries provide years rather than assessable financial results, so financial credibility cannot be confirmed. Supplier service procedures and complaint/CAPA records are documented, but the approved-supplier list lacks approval signatures or dates.

CertificationsThe company states that it has passed ISO9001:2008 quality-system certification and ISO14001:2004 environmental-management certification. The slices do not provide certificate validity dates or verification details, but they do explicitly report certification holding.

After-Sales capabilityThe company reports a professional installation team and perfect after-sales service, while service records show clear procedures for corrective/preventive actions and customer complaints. However, supplier-service evidence also shows no overseas agents or branches and no overseas-service countries, limiting demonstrated international coverage.

R&D capabilityThe supplier reports new products during the past year, design and manufacturing capability, and products holding new practical patents in China and high-tech-product recognition in Jiangsu Province. It does not provide an available SDK and does not offer ODM service, but those limitations do not negate the documented product-development evidence.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. These listed services directly demonstrate broad customization coverage.

Client casesThe company states that its products have been widely used in highways, railway bridges, and public buildings. These are explicit application references, although no named customers, project names, or independently verifiable case details are provided.
