Our Pot type bridge bearing is widely used by every bridge and highway in China. Various types can be produced according to the customers' demands. 1. Description of Chinese bridge pot bearing/bridge pot bearing manufacturer The basic elements of a Pot bridge bearing consists of a shallow cylinder, known as pot, an elastomeric pad known as disc, a single or set of sealing rings, piston and sliding surfaces. Masonry plates and base plates are common for the installation of pot bearings, as they allow attachment of the bearings and increase the support area on the pier and abutment. Pot bridge bearings are fixed against all translation unless they are used with a PTFE sliding surface. 2. Performances and Classifications of Chinese bridge pot bearing/bridge pot bearing manufacturer A: Two-way movable Bridge Pot bearing: has vertical rotation, longitudinal and horizontal gliding performances and its serial number is SX; B: One-way movable Bridge Pot bearing: has vertical rotation and one-way gliding performance and its serial number is DX; C: Fixed Bridge Pot bearing: only has vertical rotation performance and its serial number is GD. 3. Features of pot bearing manufacturer 1, Low friction coefficient
2, Good elasticity
3, Easy installation
4. Marine Pot Type Rubber Bearing 4. Advantages of pot bearing manufacturer The design advantages of our Bridge pot bearing make them particularly suitable for medium to long span structures e.g. bridges, pipelines, power stations, off shore platforms etc. The continuous research and development on DACHENG Bridge pot bearings combine simplicity, design efficiency, versatility and economy. They have gained successful track record for its quality and durability throughout the world since its introduction in 1972. 5. Application of pot bearing manufacturer Pot type rubber bridge bearing can be used in steel or concrete structures. These low profiles, compact bearings are particularly useful to transmit large vertical load while accommodating large movements and multi-directional rotation. Separate mechanisms for rotation and translation (where applicable) provide minimum eccentricity of the load and minimum frictional resistance to movement. High side loads can also be accommodated simultaneously. 6. Technical Performance of pot bearing manufacturer A: Vertical rotation angle of the bridge Pot bearing should not be less than 40’; B: Vertical bearing capacity (KN) 1000-50000 of the Bridge Pot bearing is divided into 28 grades.Horizontal bearing capacity of the non-gliding surface is 10% of the vertical. C: Friction coefficient of the Bridge Pot bearing: room temperature μ≤0.04 7. Suitable Temperature Range ( a) Room Temperature type pot bearings Apply to -25°C~ +60°C (b) Cold-resistant Type Apply to -40°C ~ +60°C (marked “F”)
