Nano Force Fatigue Test System BI-7000
The BI-7000 Nano Force Fatigue Testing Machine is a compact, high-performance servo-hydraulic test system designed for material fatigue testing under cyclic loading. Engineered for testing small to medium-sized specimens, it delivers up to 25 kN dynamic force capacity and supports a broad range of mechanical tests including tensile, compressive, flexural, fracture, and crack propagation.
Built with a compact single or dual-column load frame, the system integrates a high-resolution digital controller, servo-hydraulic actuator, and a plug-and-play Hydraulic Power Unit (HPU). The BI-7000 is optimized for low-cycle and high-cycle fatigue testing of materials such as metals, polymers, elastomers, composites, and aerospace alloys. It features high-speed data acquisition, exceptional control accuracy, and a modular fixture interface — making it ideal for R&D labs, quality assurance departments, and material development centers.
