Laminated Rubber Bearing
Laminated Elastomeric Bearing Pad
Laminated Bearing Pads for Bridges, Precast & Heavy Structures
What Is a Laminated Bearing Pad?
A laminated bearing pad, also called a laminated elastomeric bearing or steel-reinforced elastomeric bearing, is a bearing assembly made from alternating layers of elastomer and steel reinforcement.
It’s a set of alternating layers of neoprene or natural rubber along with steel plates that are moulded together under heat and pressure also called as vulcanization process that make it single unit. vulcanization process makes rubber and steel to bond together permanently. The final product is called laminated bearing pad. These pads are designed to take more load of bridge or heavy concrete structure compare to plain bearing pads.
How a Steel-Reinforced Elastomeric Bearing Works
Use the supplied section explaining:
- Vertical load transfer
- Horizontal movement
- Rotation
- External elastomer cover
- Internal elastomer layers
- Embedded steel shims
- Vulcanised bond
| Bearing element | Function in assembly | Why it matters |
|---|---|---|
| External elastomer cover | Protects reinforcement and forms bearing faces | Maintains continuous elastomeric envelope |
| Internal elastomer layers | Controlled deformation | Accommodates calculated movement |
| Embedded steel shims | Reinforce elastomer | Limits lateral bulging |
| Vulcanised bond | Joins elastomer and steel | Creates integrated bearing |
Applications
