This study presents a simplified design procedure for seismic isolators used for rigid freestanding equipment in Mexico City. The seismic response of non-anchored equipment is evaluated, focusing on stability criteria such as preventing rocking, overturning, and sliding under seismic loads. The proposed methodology calculates the initial dimensions and characteristics of the isolators, ensuring that stability requirements are met. Using governing dynamic equations, the effectiveness of the simplified design is verified, demonstrating that the equipment remains stable without initiating rocking or sliding. This approach provides a reliable framework for designing seismic isolation systems for equipment that can withstand the seismic conditions of Mexico City.
