Hengshui Ruibin New Materials LLC is a professional manufacturer specializing in high-performance elastomeric bearing pads. Since our establishment in 2019, we have focused on producing reliable, durable, and cost-effective solutions for bridge construction, building isolation, and industrial applications. Our Laminated Elastomeric Bearing Pad 300x300x50mm, Neoprene Rubber, 60 Shore A Hardness is engineered to deliver exceptional load transfer, vibration dampening, and structural movement accommodation. With a factory spanning 1,000–3,000 square meters and a skilled team of 101–200 employees, we ensure strict quality control throughout the production process. Our annual export value of US$2.5–5 million reflects our commitment to serving global markets, including North America, South America, Europe, Asia, Africa, and Oceania.
This laminated bearing pad is designed to meet the rigorous demands of modern infrastructure. The combination of neoprene rubber (polychloroprene) and internal steel reinforcement provides excellent compressive strength, flexibility, and resistance to weathering, ozone, and aging. The 60 Shore A durometer ensures optimal stiffness for heavy loads while maintaining sufficient elasticity to accommodate thermal expansion, contraction, and seismic movements. Below are the key features and technical specifications:
- Laminated Construction: Multiple layers of neoprene rubber bonded with internal steel plates (2–3 mm thick) provide enhanced load-bearing capacity and controlled shear deformation.
- Neoprene Rubber Material: Excellent resistance to UV radiation, ozone, oil, grease, and extreme temperatures (-40°C to +80°C), ensuring long service life in outdoor environments.
- Precise Dimensions: 300 mm (length) × 300 mm (width) × 50 mm (thickness) – standard size suitable for many bridge and structural applications, with customization available.
- 60 Shore A Hardness: Balanced hardness provides adequate support for vertical loads while allowing horizontal movements (shear, rotation) without excessive stress.
- Low Compression Set: Maintains shape and performance under sustained compression, minimizing maintenance requirements.
- Easy Installation: Lightweight and handled easily by two workers; no special tools required for placement.
- Compliance with ISO9001/ISO9000: Our manufacturing facility is certified under these quality management systems, ensuring consistent product quality.

Key Benefits for Your Projects:
- Structural Reliability: The laminated design ensures uniform load distribution, reducing stress concentrations on bridge piers and abutments.
- Durability in Harsh Environments: Neoprene rubber resists cracking, embrittlement, and degradation from road salts, chemicals, and UV exposure.
- Cost-Effective Solution: Compared to steel bearings or pot bearings, elastomeric pads offer lower initial cost and minimal maintenance over their lifespan.
- Quick and Simple Installation: No welding or special equipment needed; pads can be placed directly on concrete or steel surfaces.
- Flexible Movement Accommodation: Allows for thermal expansion, contraction, rotation, and horizontal shear without compromising structural integrity.
- Customizable Options: We can adjust dimensions, hardness, number of laminations, or even provide plain (non-laminated) pads upon request.

Frequently Asked Questions (FAQ):
- Q: What is the difference between laminated and plain elastomeric bearing pads? Laminated pads have internal steel plates that increase vertical load capacity and control horizontal deformation. Plain pads are suitable for lighter loads and smaller movements. Our 300x300x50mm pad is laminated for enhanced performance.
- Q: Can this bearing pad be used in seismic zones? Yes, the 60 Shore A hardness and laminated design allow for controlled shear deformation, making it effective for absorbing seismic energy when properly designed into the structure.
- Q: What is the expected service life of this pad? Under normal conditions, neoprene rubber bearing pads can last 30–50 years or more, depending on environmental factors and load history. Our neoprene is formulated for long-term durability.
- Q: Do you provide installation guidelines? Yes, we offer technical datasheets and installation instructions. We also recommend consulting a structural engineer for proper placement and bearing seat design.
- Q: Can I get a different size or hardness? Absolutely. We offer customization on dimensions, hardness (40–80 Shore A), number of laminations, and even material options (e.g., natural rubber). Please contact us with your requirements.
- Q: How do you ensure product quality? Our factory is ISO9001/ISO9000 certified. We test each batch for hardness, compression set, tensile strength, and bond integrity. Random samples undergo accelerated aging tests.
- Q: What is the minimum order quantity (MOQ)? For standard sizes, MOQ is typically 50 pieces. For custom sizes, MOQ may be higher. We can discuss flexible terms for trial orders.
- Q: What are the payment and shipping terms? We accept T/T, L/C, and other common terms. Shipment is usually FOB Tianjin or Qingdao, with delivery times 15–30 days after order confirmation.
