Product Description

Product Description

Pot Bearing with Large Load Capacity and Large Horizontal Displacement
The Pot Bearing is a critical structural component that connects the superstructure and substructure of a bridge, utilizing a combination of a steel pot and rubber to transfer loads and accommodate movements. It transmits massive vertical forces through a rubber disc constrained within the steel pot while allowing necessary rotations and horizontal displacements of the structure. As an advanced bearing solution for long-span and heavy-load bridges, it provides reliable, efficient, and economical foundational support for modern complex bridge engineering with its ultra-high load capacity, flexible displacement accommodation, and excellent multi-dimensional rotation capability.

Functions

*Strong adhesion: Initial tack ≥15N/cm, long-lasting bonding

*Excellent weather resistance: UV resistant, anti-aging

*Temperature resistance: -30℃ to +80℃ without brittleness or flowing

*Easy application: Peel and stick, no tools needed

*Eco-friendly: Solvent-free, safe and non-toxic

Product Advantages

Quick application: 5-minute repair, ready to use

Low cost: Only 3-5 yuan per meter

Wide compatibility: Bonds to metal, concrete, plastic and wood

Long service life: 5+ years outdoor use

Customizable: Flexible width, length and thickness options

Fast delivery: Regular specifications in stock, same-day shipment

Working Principle

    There is an elastomeric pad in the pot of the pot bearing, it has fluid properties when it in the state of three-phase stressed, making use of this feature can achieve large rotation of the bearing. In addition, when a relative motion occurs between the PTFE plate which placed on the piston and the stainless steel plate, horizontal displacement can be achieved. Pot bearing can meet the requirements of large end reaction, large horizontal displacement and large rotation, it is suitable for the bridge with large span and large end reaction.
