Isolation System

Natural Rubber Bearing(NRB)

As it is laminated rubber made of natural rubber, it has excellent restoring force.

Features

  • It has low attenuation (the equivalent attenuation constant is 2~3%), excellent linearity and stable restoring force.
  • A design with a high degree of freedom is allowed for types of dampers and adjustment of attenuation.
  • It has almost no dependency on changes in axial force and displacement history.
  • It maintains stable rigidity despite large deformation.

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.
