In houses and buildings

It is difficult for people living in an area with frequent earthquakes not to feel at least some anxiety. Our quake-absorbing "seismic isolator" technology is used in many homes to help ease these fears.

To protect life and property from the threat of quakes

There are two main types of anti-earthquake technology: "quake resistance", which refers to strengthened columns, beams and walls designed to be resistant against quakes, and "seismic isolation", structures installed in house foundations to absorb vibrations of the ground. If a house is directly connected to its foundations, it is also directly vulnerable to seismic vibrations. Seismic isolation structures are like a buffer that provides protection for the house. As illustrated, THK's quake-absorbing seismic isolation structures use crossed LM Guides to greatly reduce the amount of vibration transmitted from the ground to the house above.
