Lead Rubber Bearing

Lead rubber bearing is a bearing in which one or more lead cores are inserted into an ordinary plate rubber bearing to improve its damping performance. The lead rubber bearing bears the weight of the structure and horizontal forces. The lead core absorbs energy through plastic deformation with hysteresis damping, and the rubber provides horizontal restoring force . The cold-deformed lead core recrystallizes at room temperature to maintain the bearing's performance under repeated loads. The lead rubber bearing has high vertical stiffness, providing stable support for the superstructure; moderate horizontal stiffness, accommodating large displacements caused by earthquakes; and excellent damping performance, capable of withstanding large seismic events. This product can be used in bridges, buildings, and any civil engineering structure.

The company's lead rubber bearings have obtained CE certification.

Typical cases of the company's lead rubber bearing applications include:

 Jakarta LRT, Jakarta MRT, Trinidad and Tobago Churchill Roosevelt Expressway, Menghua Railway Sanmenxia Yellow River Bridge, Yunnan Awang Middle School, Yunnan Dongtang Expressway, etc.
