Some basic issues associated with development of seismic dampers (Rotary Damping series) applied to ball screw for seismic performance enhancement are studies in this paper. RD series are consists of ball screw section and damper section. RD series has 2 types of damper section, RD-tube has a tube type of damper section, RD-disk has a disk type of damper section. RD series have more efficient viscous damping force applied to amplification of ball screw.
