Hengshui Ruibin New Materials LLC, a professional manufacturer founded in 2019, offers high-quality Basin Type Pot Bearing Elastomeric Pad Support for Bridge Construction. Our factory spans 1,000–3,000 square meters and employs 101–200 skilled workers, with an annual export value of US$2.5–5 million. This product is engineered to deliver exceptional load-bearing capacity, rotational flexibility, and long-term durability for modern bridge projects. Combining a robust steel basin with a high-performance elastomeric pad, it effectively absorbs vibrations, accommodates thermal movements, and ensures structural stability under heavy traffic loads.
The basin type pot bearing system is widely recognized for its ability to handle large vertical and horizontal forces while allowing controlled rotation and translation. The elastomeric pad component further enhances performance by providing uniform stress distribution and reducing noise. Designed for use in highway bridges, railways, and viaducts, this bearing is available in customizable sizes and load capacities to meet specific project requirements. Our products are manufactured under strict ISO9001 and ISO9000 quality management systems, ensuring consistent reliability and safety.
Key Features & Technical Specifications
- High Load Capacity: Supports vertical loads from 1000 kN up to 50000 kN, with options for higher capacities upon request.
- Rotational Flexibility: Allows rotation of 0.02 to 0.05 radians (standard), accommodating bridge deck deformations.
- Horizontal Displacement: Can be designed for horizontal movement up to ±100 mm (customizable).
- Durable Construction: Steel basin is made from high-strength structural steel with anti-corrosion coating; elastomeric pad uses natural rubber or neoprene with excellent aging resistance.
- Temperature Resistance: Operates effectively from -40°C to +60°C, suitable for extreme climates.
- Low Maintenance: Sealed design prevents dirt and moisture ingress, reducing inspection frequency.
- Easy Installation: Pre-assembled units with anchor bolts and grouting templates simplify on-site work.
- Customizable Options: Different pad hardness, steel grades, and surface finishes available.

Frequently Asked Questions (FAQ)
Q1: What is the difference between a basin type pot bearing and a standard elastomeric bearing?
A: A basin type pot bearing combines a steel basin with a confined elastomeric pad, providing higher load capacity and rotational capability compared to a plain elastomeric bearing. It is ideal for large bridges where significant movement and forces are expected.
Q2: Can the bearing accommodate thermal expansion and contraction?
A: Yes, the elastomeric pad allows for both rotation and horizontal translation, effectively accommodating thermal movements and creep of the bridge deck.
Q3: What is the typical lifespan of this bearing?
A: Under normal conditions, the design life is 20–30 years. Regular inspection every 5 years is recommended to ensure optimal performance.
Q4: Do you provide custom sizes and load ratings?
A: Absolutely. We can customize dimensions, load capacity, rotation angle, and horizontal displacement based on your bridge design drawings. Contact us with your requirements.
Q5: What certifications are available?
A: Our products are manufactured under ISO9001 and ISO9000 certified systems. We can also provide test reports for material properties and performance upon request.
Q6: How are the bearings packaged for shipping?
A: Each bearing is individually wrapped with waterproof plastic, secured on wooden pallets, and covered with steel strapping. Export-quality packaging ensures safe transportation via sea or land.
Q7: What is the lead time for mass production?
A: Typically 30–45 days after order confirmation and design approval. For urgent projects, we can expedite within 20 days, subject to production capacity.
Q8: Do you offer installation support?
A: Yes, we provide detailed installation manuals and optional on-site technical guidance by our engineers. We also offer training videos for your team.
