Bearings and seismic isolation devices are key load transfer and protection components installed between the superstructure and substructure of bridges, buildings and other engineering structures. Their primary functions include transmitting vertical loads, accommodating horizontal displacements and rotational deformations, and dissipating seismic energy. Applications span highway and railway bridges, large public buildings, industrial plants and equipment foundations.

Based on differences in structural type, material composition and working mechanism, bearing products are grouped into multiple categories. Each category offers specific characteristics in load capacity, displacement performance and applicable scenarios, allowing precise selection for different engineering conditions.

Rubber Bearing

Made from materials such as natural rubber or chloroprene rubber, this type utilizes the high elasticity of rubber to accommodate superstructure displacement and rotation while uniformly transferring loads to the substructure. The product range covers laminated rubber bearings and PTFE sliding rubber bearings for bridges, featuring high vertical stiffness and favorable horizontal flexibility, making it a commonly used support solution for small to medium span bridges.

Industrial Rubber Pad

A solid pad product made primarily from rubber, used beneath equipment foundations, machine bases and heavy components to provide vibration damping, load distribution and foundation surface protection. Dimensions and cross sections can be cut or customized according to actual needs, with material hardness and elastic modulus flexibly selected, offering an economical and practical choice for industrial support applications.

Spherical and Pot Bearing

High performance bearings primarily composed of metal components. Spherical bearings achieve multi directional rotation through spherical contact, offering flexible rotation and uniform displacement in all directions, and are suitable for locations with demanding load and displacement requirements in long span bridges and large buildings. Pot bearings utilize the high elastic modulus of confined rubber to transfer vertical loads, featuring high load capacity and compact structure, and demonstrate notable advantages in addressing high bearing capacity and compact space needs in long span and large bridge projects.

Seismic Isolation Rubber Bearing

A high performance rubber support device specifically designed for structural seismic and vibration mitigation. By extending the natural vibration period of the structure and increasing damping energy dissipation, it effectively reduces the dynamic response under earthquake action. Based on functional characteristics, it is divided into natural rubber bearings (LNR), lead rubber bearings (LRB) and high damping rubber bearings (HDRB), widely used in buildings and bridge projects located in high seismic intensity zones.
