Key Features & Technical Specifications
- Material Excellence: Made from high-quality natural rubber, providing excellent elasticity, fatigue resistance, and environmental adaptability.
-
Two Configuration Options:
- Plain Bearings: Single-layer rubber block without reinforcement – ideal for small to medium structures where simple vertical load support is needed.
- Laminated Bearings: Multi-layer rubber bonded with steel plates – offers superior shear displacement capacity and rotational flexibility, suitable for large-span bridges and seismic zones.
- Customizable Dimensions: Available in various sizes, thicknesses, and hardness levels to match specific project requirements. Contact us for tailored solutions.
- Load Capacity: Standard models support up to 5000 kN; higher capacities available upon request.
- Temperature Range: Reliable performance from -30°C to +60°C, with optional low-temperature formulations for cold climates.
- Compliance & Certification: Manufactured under ISO 9001:2015 and ISO 9000 quality management systems, ensuring consistent quality and traceability.

Frequently Asked Questions
Q1: What is the difference between plain and laminated natural rubber bridge bearings?
A: Plain bearings consist of a single layer of natural rubber, suitable for simple vertical load support in small to medium bridges. Laminated bearings have multiple rubber layers bonded with steel plates, offering higher shear displacement capacity and rotational flexibility – ideal for large-span bridges and seismic applications.
Q2: What is the typical service life of these bearings?
A: Under normal environmental conditions, natural rubber bearings can last 30–50 years or more. Regular inspection and maintenance can further extend their lifespan.
Q3: How do I choose the right hardness and size for my project?
A: We recommend consulting our technical team. Standard hardness is 60±5 Shore A, but custom hardness (50–70 Shore A) is available. Dimensions are fully customizable based on bridge design loads and movement requirements.
Q4: Are these bearings suitable for cold climates?
A: Yes, natural rubber performs well down to -30°C. We also offer low-temperature compound formulations for extreme cold environments (up to -50°C) upon request.
Q5: Can you provide samples for testing?
A: Absolutely. We can supply small samples for evaluation. Please contact us with your specifications, and we will arrange shipment.
Q6: What certifications do your products hold?
A: Our manufacturing facility is ISO 9001:2015 and ISO 9000 certified. We also comply with international standards such as AASHTO and EN 1337 where required.
Q7: How are the bearings packaged for export?
A: We use sturdy wooden pallets or steel frames with protective wrapping to prevent damage during shipping. Each bearing is individually labeled for easy identification.
Q8: What is the typical lead time for an order?
A: Lead time depends on quantity and customization. Standard products typically ship within 15–25 working days after order confirmation. Custom orders may require 30–45 days.
