Product Description

Product Description

Spherical Bridge Bearing – Low Friction and Excellent Accommodation Feature

Spherical bridge bearing, also called spherical bearing, spherical bearing pad, is designed to ensure vertical and horizontal forces transferring under control which is a connection devices between superstructures and substructures. It consists of steel plate enclosed with edge sliding guide and stainless steel panel for sliding controlling, under the stainless steel panel is a PTFE sheet, which is recessed into the steel to a depth and contains a special lubricant to ensure permanent lubrication of the sliding surfaces. Then there is a stainless steel panel with a convex bottom face to facilitate rotations. The bottom component is concave steel plate that covered with a recessed PTFE sheet to transfer whether horizontal or vertical forces safely.

Classification

The spherical bridge bearings are classified into three types according to different sliding direction.

    *Fixed type. Provide rotations capacity from any direction only.
    *Guided type (Uni-directional sliding). Rotation plus movement in one direction.
    *Free sliding (multi-directional sliding). Rotation plus movement in all directions.

Function

*Effective Seismic Isolation: Extends the structural period to avoid the predominant seismic period, significantly reducing the seismic response of the upper structure.
*Energy Absorption: Efficiently dissipates seismic energy through hysteretic deformation (plastic deformation of the lead core or internal friction of high-damping rubber).
*Load Support: Provides high vertical load-bearing capacity and stiffness to stably support the weight of the upper structure.
*Displacement Adaptation: Allows significant horizontal shear deformation to accommodate movements caused by temperature changes, shrinkage, and other factors.

Product Features

*High Damping Performance: HDR and LRB bearings can achieve an equivalent damping ratio of 10% to 20% or higher, offering remarkable energy dissipation.

*Self-Centering Capability: Exhibits excellent elastic recovery after earthquakes, minimizing residual structural deformation.

*Strong Durability: The product is resistant to aging, fatigue, and harsh weather conditions, with a long design service life comparable to that of the building structure.

*Eco-Friendly Design: HDR bearings do not use lead, avoiding heavy metal pollution and aligning with green building principles.
