The SF1491 EMSY Spring Testing System determines detailed force line (load center) information on automotive suspension springs. The SF1491 is a floor standing electromechanical testing machine equipped with Instron
® EMSY load cell system that determines the true response vector of a coil compression spring under load. This information is used by spring manufacturers and suspension design engineers to develop suspensions for automobiles, light trucks, and suvs with better and safer ride characteristics. The system uses nine load cells to accurately determine the center of load position on the upper and lower spring bearing surfaces, as well as all axial and lateral loads and moments generated by the spring.
Range of Models
