The SF1390 is a motor-driven spring testing system designed to perform testing on tension and compression springs and other spring-type products. The system has a floor-standing design with two lead screws and two precision guide columns for maximum stiffness. A servo drive controls the frame’s loading crosshead for fully automatic load testing with speeds up to 1,000 millimeters per minute. The system is available in two frame capacities: 50 kilonewtons and 100 kilonewtons. The spring testing load cells incorporate mechanical overload stops and at least 300% overload capacity, minimizing the chance of load cell damage during overload conditions.
