The Instron 8850 series system is a floor model biaxial servohydraulic dynamic test system that provides axial and torsional load on a specimen in an integrated biaxial actuator. With a precision aligned, high-stiffness twin-column frame, the 8850 series meets the challenging demands of a varied range of both static and dynamic biaxial testing requirements. For static and fatigue testing, the 8850 series offers axial-torsion systems capable of axial and torsional loading of up to 2000Nm and 250kN, respectively.
