Product Description

Product Description

Lead rubber bearing, also called lead core rubber bearing, LNR rubber bearing, has similar structure with high damping rubber bearing. It is an important component of seismic isolation bearing. It is composed of laminated rubber bearing and lead core. The lead core can not only bear the heavy load and horizontal force, but also absorb energy through plastic deformation of hysteresis damping.

Lead rubber bearing can be divided into round and rectangular shapes for different application. Additional, the lead core quantity can be single or multiple to supply maximum flexibility in the bridges or building.

I Type Connector plate connect to top surface plate by bolts
Rubber cover layer bond to internal plate
  Rubber elastomer layer cover all bearing after vulcanization
II Type Connector plate bond to internal elastomer
III Type Bearing connected to connector plate by groove or dowel

Feature

  • Stable vertical stiffness and excellent vertical loading capacity.
  • Suitable horizontal stiffness. Satisfy the earthquake vibration and normal displacement. It can enlarge the vibration cycle to 1.5 to 3 seconds.
  • Excellent damping performance.
  • Good energy dissipation capacity.
  • Adjustable lead core area. It can suit different damping ratio through adjusting wire diameter and sectional area.
  • Excellent durability, cycle fatigue resistance, acid and alkali resistance.
  • Long lifespan. 60-80 years long lifespan for durability.
  • Easy installation and replacement for lower maintenance costs.Lead Rubber Bearing Isolator (LRB) Bridge Bearing

Application

Lead rubber bearing, main branch of seismic isolation system, is widely applied to the large sized structures such as road bridges, rail bridges and nuclear power station to minimize damages from dynamic loads like earthquake.
