Hengshui Ruibin New Materials LLC, a professional manufacturer established in 2019 with a factory of 1,000–3,000 square meters and 101–200 skilled employees, presents our Rectangle and Round Basin Type Seismic Isolation Rubber Elastomeric Pot Bridge Bearing. This advanced bearing is designed to provide superior seismic protection, rotational flexibility, and horizontal displacement for various bridge types. With ISO9001 and ISO9000 certified production processes, we ensure every unit meets the highest quality standards, making it a reliable choice for infrastructure projects worldwide.
Our pot bearing combines a robust steel pot, a natural rubber elastomeric pad, and a durable sealing system to accommodate large loads while maintaining low friction. The rectangle and round basin configurations allow for easy installation and optimal performance in both straight and curved bridge decks. Whether you need standard sizes or customized solutions, our engineering team can tailor the bearing to your specific load, rotation, and displacement requirements.
Key Features & Technical Specifications
Seismic Isolation: The rubber elastomeric core absorbs and dissipates seismic energy, reducing structural damage during earthquakes.
High Load Capacity: Supports vertical loads from 500kN up to 50,000kN, suitable for small to large-span bridges.
Rotation Capability: Allows rotation up to 0.02 rad (or more upon request) to accommodate deck deformations.
Horizontal Displacement: Provides ±50mm to ±200mm horizontal movement, adaptable to thermal expansion and contraction.
Low Maintenance: Sealed design prevents dust and moisture ingress, extending service life.
Customizable Dimensions: Both rectangle and round basin shapes available, with custom sizes per project drawings.
Durable Materials: High-quality natural rubber and structural steel, resistant to aging and corrosion.

Frequently Asked Questions
Q1: What is the maximum load capacity of your pot bearing?
A: Our standard range covers 500kN to 50,000kN. For larger loads, we can design custom solutions based on your project specifications.
Q2: Can the bearing accommodate both rectangle and round basin shapes?
A: Yes, we offer both rectangle and round basin types. The shape can be selected according to the bridge deck geometry and structural requirements.
Q3: What is the expected service life of the bearing?
A: With proper installation and maintenance, the bearing can last 50 years or more. The rubber elastomeric pad is formulated for long-term durability under various environmental conditions.
Q4: Do you provide horizontal displacement customization?
A: Absolutely. The horizontal displacement can be customized from ±50mm to ±200mm, or even larger if needed, to match thermal movements and seismic demands.
Q5: Is the bearing suitable for high seismic zones?
A: Yes, the seismic isolation rubber elastomeric design is specifically engineered to absorb and dissipate seismic energy, making it ideal for earthquake-prone areas.
Q6: What materials are used in the bearing?
A: The main components are natural rubber (or chloroprene rubber) for the elastomeric pad, high-strength structural steel for the pot and piston, and a stainless steel sliding surface for low friction.
Q7: How do you ensure quality control?
A: We follow ISO9001 and ISO9000 certified procedures. Each bearing undergoes load testing, rotation testing, and sealing inspection before shipment. Third-party inspection is also available upon request.
Q8: What are the shipping ports and delivery time?
A: We ship from Port of Tianjin or Port of Qingdao. Typical delivery time is 30–45 days after order confirmation, depending on quantity and customization.
