Bearing is an important component used to support and fix building structures, playing a crucial role in bearing and transferring loads. There are many important product classifications of bearings, mainly based on their purpose and material. Below is a detailed introduction to the important product classifications of bearings.

Firstly, according to the purpose of the bearing, bearings can be classified into bridge bearings, building bearings, and mechanical bearings, etc. Bridge bearings are mainly used in bridge structures to support the beams of the bridge and bear the loads of the bridge. Building bearings are mainly used in building structures to support the columns and walls of the building, bearing the loads of the building. Mechanical bearings are mainly used in mechanical equipment to support the base of the mechanical equipment and bear the weight and vibration of the mechanical equipment.

Secondly, according to the material of the bearing, bearings can be classified into rubber bearings, steel bearings, concrete bearings, and composite bearings, etc. Rubber bearings are mainly made of rubber materials, with good shock absorption and sound insulation effects, suitable for bridge and building structures. Steel bearings are mainly made of steel materials, with high load-bearing capacity and durability, suitable for large bridges and building structures. Concrete bearings are mainly made of concrete materials, with high compressive and seismic resistance, suitable for large building structures. Composite bearings are composed of multiple materials, with various advantages, suitable for special engineering requirements.

In addition, according to the structural form of the bearing, bearings can be classified into fixed bearings, sliding bearings, and rotating bearings, etc. Fixed bearings are a basic form of bearings, used to fix the columns and walls of building structures, without moving function. Sliding bearings are a special form of bearings, with certain sliding function, used to withstand the deformation and vibration of building structures. Rotating bearings are a special form of bearings, with certain rotating function, used to withstand the rotation and deformation of building structures.

In summary, bearings are important building structure components with various product classifications. Depending on the purpose, material, and structural form of the bearing, bearings can be classified into bridge bearings, building bearings, and mechanical bearings, rubber bearings, steel bearings, concrete bearings, and composite bearings, fixed bearings, sliding bearings, and rotating bearings, etc. Different types of bearings have different application values in different engineering projects, providing important support and protection for the safety and stability of building structures.
