Welcome to Hengshui Ruibin New Materials LLC – your trusted manufacturer of high-performance elastomeric bearings. Our PTFE Sliding Elastomeric Bearing Pad with Natural Rubber Shock Absorption is engineered to deliver exceptional durability, low friction, and superior vibration isolation for demanding structural applications. Combining a premium PTFE sliding surface with a resilient natural rubber core, this bearing pad effectively accommodates thermal expansion, seismic movement, and dynamic loads while protecting the superstructure from fatigue and damage. Whether you are designing a highway bridge, a high-rise building, or an industrial plant, our bearing pads ensure long-term service life and minimal maintenance.
Key Features & Technical Specifications
- PTFE Sliding Surface: Ultra-low coefficient of friction (typically 0.04–0.08) allows smooth horizontal movement under high compressive loads, reducing stress on substructures.
- Natural Rubber Elastomer Core: Excellent elasticity and energy absorption capacity, providing effective shock and vibration damping for bridges and buildings.
- Reinforced Construction: Internal steel laminates (optional) increase vertical load capacity and prevent lateral bulging, ensuring dimensional stability under heavy loads.
- Weather & Chemical Resistance: Natural rubber compound formulated with antioxidants and anti-ozonants to resist aging, UV exposure, and mild chemical attack.
- Customizable Dimensions: Available in various thicknesses, widths, and lengths to fit specific project requirements. Sizes up to 1000mm × 1000mm available.
- Easy Installation: Pre-drilled holes or adhesive bonding options simplify placement on concrete or steel substructures.

Advantages & Customer Benefits
- Extended Structure Lifespan: By absorbing seismic and thermal movements, our bearing pad reduces stress concentrations in concrete and steel elements, preventing cracks and fatigue failures.
- Low Maintenance: The PTFE layer resists wear and requires no lubrication under normal conditions, cutting long-term operating costs.
- High Load Capacity: Reinforced designs can support vertical loads up to 5000 kN, suitable for medium to large span bridges.
- Noise and Vibration Reduction: Natural rubber's inherent damping properties significantly lower transmitted vibrations and structure-borne noise, improving occupant comfort in buildings.
- Flexible Design: We can adjust the rubber thickness, PTFE layer, and internal steel plates to meet specific deflection, rotation, and sliding requirements.
- Global Compatibility: Our pads comply with international standards (AASHTO, BS EN, etc.) and have been exported to over 30 countries.

Frequently Asked Questions (FAQ)
-
What is the difference between a PTFE sliding elastomeric bearing and a standard elastomeric bearing?
Standard elastomeric bearings rely solely on rubber deformation to accommodate movement, while PTFE sliding bearings incorporate a low-friction PTFE layer that allows larger horizontal displacements with minimal resistance. This is essential for long-span bridges and structures with high thermal expansion. -
How long is the service life of this bearing pad?
Under normal environmental conditions (temperature range, UV exposure), our bearing pads are designed for a service life of 20–30 years. The natural rubber compound includes anti-aging additives, and the PTFE surface is highly resistant to wear. Periodic inspection is recommended every 5–10 years. -
Can I get custom sizes and shapes?
Yes, we offer custom sizes, thicknesses, and shapes to fit your specific project needs. Please provide your design drawings or load requirements, and our engineers will recommend the optimal configuration. -
What is the maximum load capacity of these pads?
Standard pads can support compressive loads up to 15 MPa (approx. 1500 kN for a 300×300 mm pad). With reinforced internal steel plates, capacities can exceed 5000 kN. We can customize for even higher loads. -
Are these bearings suitable for seismic zones?
Yes, the natural rubber elastomer provides excellent energy dissipation, reducing seismic forces transmitted to the structure. Combined with PTFE sliding capability, they effectively accommodate ground motion displacements. For high-seismic applications, we can also add lead-core or high-damping rubber options. -
How do I install the bearing pad?
Installation typically involves placing the pad on a clean, level concrete or steel surface. For sliding applications, the PTFE side should face the moving part. The pad can be bonded with epoxy adhesive or fixed using mechanical anchors. Detailed installation instructions are provided with each order. -
What is the minimum order quantity (MOQ)?
For standard sizes, MOQ is 50 pieces. For custom designs, MOQ may be higher depending on tooling and production setup. We also accept small trial orders for testing purposes. -
Do you provide third-party testing reports?
Yes, we can arrange testing by accredited laboratories for compressive strength, friction coefficient, hardness, and aging resistance upon request. Additional costs may apply.
