Cast steel bearings: Made of carbon steel or high-quality steel, through molding, sand turning, casting, machining and heat treatment and other processes. This type of bearing has a strong structure, but it has the disadvantages of large size, high steel consumption, easy rust and high maintenance costs
New Steel Bearings Stainless steel or alloy steel bearings: If 30CrMnTi alloy steel is used, it has high strength (tensile strength up to 1105MPa) and high shear strength (585MPa) after quenching and quenching treatment, and can pass 200,000 cyclic load tests, suitable for high-stress parts, and improve seismic resistance and durability
Sliding plate steel bearings: Reduce friction through sliding surfaces and adapt to the horizontal displacement of bridges
Spherical bearing (point bearing): The upper and lower contact surfaces are spherical, adapting to multi-directional rotation, and are often used in occasions where flexibility is required
Reinforced concrete bearings: Such as swing column bearings, reinforced concrete short columns are used instead of traditional rollers, which are suitable for bridges with large spans
Rubber bearings: Including plate rubber bearings and basin rubber bearings, composed of multiple layers of rubber and stiffeners, using the elasticity of rubber to absorb vibration, suitable for scenarios with high shock absorption requirements
