GBZY450*84 Circular Plate Bridge Bearing Price Rubber Bearing Production

Plate rubber bearings are a type of bridge bearing product made by embedding, bonding, and vulcanizing multiple layers of natural rubber with thin steel plates. This type of rubber bearing has sufficient vertical stiffness to withstand vertical loads and can reliably transfer the pressure from the superstructure to the piers. It also possesses good elasticity to accommodate rotation at the beam ends and significant shear deformation to meet the horizontal displacement requirements of the superstructure.

I. Rectangular (Circular) Plate Rubber Bearings

(1) Performance: They have sufficient vertical stiffness to withstand vertical loads and good elasticityGBZY450*84 Circular Plate Bridge Bearing Price Rubber Bearing Manufacturer to accommodate rotation at the beam ends, as well as significant shear deformation to meet the horizontal displacement of the superstructure.

(2) Features: This product is widely used in bridge construction, hydropower engineering, and building seismic facilities. Compared to traditional steel bearings, it offers simple construction, easy installation, steel savings, low cost,GBZY450*84 Circular Plate Bridge Bearing Price Rubber Bearing Manufacturer simple maintenance, and easy replacement. Additionally, it has a low building height, which is beneficial for bridge design and cost reduction. It also provides excellent seismic isolation, reducing the impact of live loads and seismic forces on structures.

II. Polytetrafluoroethylene (PTFE) Sliding Plate Rubber Bearings

(1) Features: This product is made by bonding a 1.5-3mm thick polytetrafluoroethylene plate onto an ordinary plate rubber bearing. In addition to possessing the vertical stiffness and elastic deformation of ordinary plate rubber bearingsGBZY450*84 Circular Plate Bridge Bearing Price Rubber Bearing Manufacturer, enabling it to withstand vertical loads and accommodate beam end rotation, the low friction coefficient (μ≤0.03) between the PTFE and the stainless steel plate at the beam bottom allows unlimited horizontal displacement of the bridge superstructure.
