PTFE rubber bearings refer to supporting components that support the weight of containers or equipment and fix them in a certain position, while also bearing vibration and seismic loads during operation. There are various types of rubber bearings, including plate type rubber bearings, bowl type rubber bearings, and spherical rubber bearings. Each type of support has its own specifications, such as plate rubber supports, which can be divided into rectangular plate rubber supports, circular plate rubber supports, and PTFE sliding plate rubber supports. It is made up of multiple layers of natural rubber embedded, bonded, and vulcanized with two or more thin steel plates of the same thickness. The naming of rubber bearings is relatively simple, starting with a letter indicating its type. GYZ stands for circular rubber bearings, GJZ stands for rectangular rubber bearings, GPZ stands for basin type rubber bearings, and the following letter codes indicate the size, bearing capacity, sliding condition, rubber type, and other parameters of the bearings. For example, GJZF4400 * 500 * 43 (CR) represents a chlorobutyl rubber plate type rubber bearing with a length of 400mm, a width of 500mm, and a thickness of 43mm.
The performance of rubber bearings: sufficient vertical stiffness to withstand vertical loads, good elasticity to adapt to the rotation of beam ends; There is also significant shear deformation to meet the horizontal displacement of the upper structure.
Characteristics of rubber bearings: This product has been widely used in bridge construction, hydropower engineering, and building seismic facilities. Compared with the original steel bearings, it has the advantages of simple structure, convenient installation, steel saving, low price, easy maintenance, and easy replacement. Moreover, the low building height of this product is beneficial for bridge design and cost reduction; It has a good seismic isolation effect, which can reduce the impact of live loads and seismic forces on buildings.
