Product Q&A
Q:What is a lead core rubber bearing and how does it work?
A:
A laminated rubber bearing with a central lead plug that provides hysteretic energy dissipation during earthquakes while supporting vertical loads.
Q:Q2: What vertical load and displacement can your LRB support?
A:
Vertical loads up to 30,000 kN; design displacement up to 400 mm, fully tested per EN 15129 and AASHTO standards.
Q:Q3: What is the damping performance of the lead core?
A:
Equivalent viscous damping of 25-30%, reducing seismic forces by effectively absorbing earthquake energy through lead plastic deformation.
Q:Q4: What makes LRB different from conventional elastomeric bearings?
A:
The lead core adds high damping without external devices-- one unit combines load bearing, isolation, and energy dissipation.
Q:Q5: What certifications and test reports do you provide?
A:
ISO 9001/14001/45001, CE (EN 15129:2018, ICR/VC/HE240505), and CNAS-accredited type inspection (Report A34915F202510476).
