A new device for reduction of seismic response of mechanical system is developed. The device is friction bearing which consists of upper and lower plates with spherical concaves and spherical metals. Seismic response is reduced by friction between plates and metals. A console rack is set on the device and shaken by the shaking table. Acceleration response of rack is measured. The maximum values of the response and the excitation, sum of squares and power spectrum are obtained. It is concluded that the repose is significantly reduced.
