Seismic Isolation

THK Seismic Isolation Systems protect your property

A company's business continuity is often called into question. Many believe that business continuity requires an enormous amount of effort, but there are some things that can be done without major difficulty, such as installing seismic isolators that protect the valuable property of a company from earthquakes.

Linear guide CLB

 

Linear re-circulating guide CLB

The linear re-circulating guide CLB is a seismic isolation system that accommodatesa heavy sustained load with extremely low frictional force, since the balls in the LM guide rotate on raceways cut into the LM rail while circulating through the block. Since the LM block is equipped with an LM rail and balls, the bearings can also accept a pulling load.Contact THK for detail


Viscous damping system RDT

 

Viscous damping system RDT

This system absorbs earthquake force transmitted to the building with the resistance offered by a viscous substance. The viscous damping system RDT has a structure in which linear motion is converted via a ball screw nut into rotary motion. A shearing force is applied to the viscous substance between the inner tube, which connects to the nut, and a fixed outer tube. Contact THK for detail


Recovery system

 

Recovery system

When an earthquake occurs, houses with isolated bases can freely move away from their foundations in any horizontal direction. Therefore, they need to return to their original positions when the earthquake ends. For that purpose they are equipped with this recovery system, which incorporates laminated rubber and other materials.Contact THK for detail
