Hengshui Ruibin New Materials LLC, a professional manufacturer established in 2019 with a 1,000–3,000 sqm factory and 101–200 employees, proudly presents our Elastomeric Bearing. This product carries a 5-year warranty, includes a Mill Test Report for every batch, and is engineered to order to meet your exact structural requirements. With an annual export value of US$2.5–5 million and shipments via Tianjin and Qingdao ports, we serve markets across North America, South America, Europe, Asia, Africa, and Oceania.
Our elastomeric bearings are designed to accommodate movements and rotations in bridges, buildings, and other civil structures while transferring loads safely. The rubber compound is carefully selected and tested to ensure long-term durability under temperature extremes, UV exposure, and dynamic loads. Each bearing is manufactured under strict ISO 9001 quality control, and the Mill Test Report provides full traceability of material properties.
Key Features & Technical Specifications
- High-Quality Rubber Compound: Natural rubber or neoprene with excellent elasticity and fatigue resistance.
- Steel Reinforcement Layers: Internal steel plates (mild steel or stainless steel available) ensure vertical load capacity while allowing horizontal deformation.
- Customizable Dimensions: Length, width, thickness, and number of layers designed per your structural specifications.
- Mill Test Report Included: Each bearing batch is tested for tensile strength, elongation, hardness, compression set, and bond strength. Reports are provided with shipment.
- 5-Year Warranty: Covers material defects and workmanship under normal service conditions.
- Engineered to Order: Our engineering team works with your drawings to produce bearings that match exact load, rotation, and movement requirements.
- Low Maintenance: No moving parts, no lubrication needed – suitable for harsh environments.
| Parameter | Value / Range | Notes |
|---|---|---|
| Hardness (Shore A) | 50–70 | Customizable per request |
| Tensile Strength | ≥ 15 MPa | Tested per ASTM D412 |
| Elongation at Break | ≥ 400% | Ensures flexibility |
| Compression Modulus | 1.5–5.0 MPa | Depends on shape factor |
| Operating Temperature | -40°C to +70°C | Special compounds available for wider range |
| Maximum Rotation | Up to 0.05 rad | Depends on design |
| Maximum Horizontal Movement | Up to 50 mm | Can be increased with sliding layer |
Applications & Benefits
- Highway & Railway Bridges: Accommodates thermal expansion, traffic loads, and seismic movements.
- Building Isolation: Reduces vibration transmission in structures near railways or industrial zones.
- Offshore & Marine Structures: Resistant to saltwater corrosion when using neoprene.
- Cost-Effective: Lower initial cost compared to pot bearings or spherical bearings, with minimal maintenance.
- Fast Delivery: As a manufacturing company with 101–200 employees, we can produce large quantities efficiently. Lead times are typically 15–30 days depending on complexity.

Frequently Asked Questions
Q1: What is the typical lead time for custom elastomeric bearings?
A: Lead time is typically 15–30 working days after drawing approval, depending on quantity and complexity. Rush orders are available upon request.
Q2: Can you provide a sample for testing before mass production?
A: Yes, we can produce samples for evaluation. Sample cost is negotiable, and we can arrange shipping via express courier.
Q3: What certifications do your bearings have?
A: Our factory is ISO 9001 and ISO 9000 certified. Individual bearings are tested per relevant standards (e.g., AASHTO, BS, EN). We can also provide third-party testing if required.
Q4: How do you ensure the quality of the rubber compound?
A: We perform incoming raw material inspection, in-process control, and final product testing. The Mill Test Report included with each batch covers tensile strength, elongation, hardness, and compression set.
Q5: What is the maximum size or load capacity you can produce?
A: There is no fixed limit – we can design bearings for capacities up to 5000 kN or more. Please provide your load and movement requirements for a tailored solution.
Q6: Do you offer bearings with a slip surface (PTFE) for larger horizontal movements?
A: Yes, we can combine elastomeric bearings with a PTFE sliding layer to accommodate movements beyond the standard rubber shear limit. This is an optional customization.
Q7: What is the warranty coverage?
A: The 5-year warranty covers defects in material and workmanship under normal service conditions. It does not cover damage due to improper installation, overloading, or extreme environmental conditions beyond design specifications.
Q8: How do I place an order for engineered-to-order bearings?
A: Please send us your structural drawings, load data, movement requirements, and any special requests. Our engineering team will review and provide a detailed proposal including drawings, calculations, and pricing.
