Isolation System

Natural Rubber Bearing(NRB)

Crafted from natural rubber, the laminated rubber exhibits outstanding restoring force

Features

  • Low attenuation, with an equivalent attenuation constant of 2-3%
  • Excellent linearity and stable restoring force
  • High design flexibility for various damper types and attenuation adjustments
  • Minimal dependency on changes in axial force and displacement history
  • Maintains stable rigidity despite large deformation22

Isolation System

Lead Rubber Bearing(LRB)

As it uses lead plugs with high attenuation, it possesses both attenuation and restoring force at the same time.

Features

  • It uses lead plugs with high attenuation
  • The natural laminated rubber fuctions as a spring, and the lead functions as a damper.
  • It is easy to install without a separate damper.
  • It is possible to adjust damping amount by controlling the number and size of lead.

Isolation System

High Damping Rubber Bearing(HDRB)

As it is laminated rubber made of specially mixed high damping rubber, the rubber itself has damping capacity.

Features

  • It is laminated rubber with high damping rubber
  • Rubber materials play the functions of both springs and damping materials themselves.
  • It is easy to install without a separate damper.
  • Its hysteresis curve remains relatively smooth.
