Rectangular Laminated Elastomeric Bearing Pads

Rectangular Laminated Elastomeric Bearing Pads are essential components in bridge and structural engineering, designed to support vertical loads while accommodating horizontal movement and rotational deflection. These bearing pads are constructed by alternating layers of high-strength natural or chloroprene rubber and steel plates, which are vulcanized together to form a durable, flexible unit. The laminated structure allows the pad to effectively distribute loads, absorb vibrations, and adapt to movements caused by thermal expansion, traffic loads, or seismic activity. Ideal for use in straight-span bridges, viaducts, flyovers, and buildings, rectangular laminated elastomeric bearing pads provide long-term performance, excellent weather resistance, and are commonly specified for structures requiring precise load transfer and movement control.

Aohong manufactures high-performance Rectangular Laminated Elastomeric Bearing Pads for bridge and structural applications. These bearing pads are composed of alternating layers of natural rubber (NR) or chloroprene rubber (CR) and internal steel plates, all vulcanized together to form a durable, load-bearing elastomeric system. Engineered to absorb vibrations, accommodate structural movements, and provide stable vertical load transfer, these bearing pads ensure long-lasting bridge and building performance.

Rubber Material Options and Temperature Range

Rectangular Laminated Elastomeric Bearing Pads are available in two standard rubber materials:

• Chloroprene Rubber (CR): Suitable for working temperatures from -25°C to +60°C.

• Natural Rubber (NR): Ideal for colder climates, with a temperature range from -40°C to +60°C.

Reinforced Structural Design with Steel Layers

Each pad consists of multiple layers of rubber bonded with steel plates (typically 2 to 5 layers), ensuring:

• High vertical load capacity

• Enhanced shear resistance

• Reliable rotation accommodation at beam ends

•
