8874 Axial-Torsion Servohydraulic Fatigue Testing System - 1

8874 Axial-Torsion Servohydraulic Fatigue Testing System The Instron® 8874 is a compact tabletop axial-torsion servohydraulic testing system that meets the challenging demands of various static and dynamic tests. The system carries out axial, torsion, or combined axial-torsion tests. With the actuator in the upper crosshead and a lower t-slot table, the 8874 makes an ideal platform for testing a variety of medical devices, biomaterials, advanced materials, and other components testing. Features • Double-acting servohydraulic actuator with force capacity up to ±25 kN (±5620 lbf) and torque capacity of ±100 Nm (880 in-lb) • Adjustable upper crosshead with hydraulic lifts and manual locks fitted as standard for easy adjustment of daylight • High-stiffness, precision aligned load frame with twin columns and actuator in upper crosshead • Patented1 Dynacell™ load cell technology for faster testing and reduction of inertial errors • 100 mm (4 in) of usable axial stroke and ±130° of rotation • Compact tabletop servohydraulic fatigue testing system – frame requires less than 0.4 m² (4.3 ft²) of space • Designed for both dynamic and static testing on a variety of materials and components • Choice of hydraulic configuration and dynamic performance to suit application • Extra-height frame option for testing longer load strings • Designed to be used with the 3520 Series of Hydraulic Power Units • Compatible with a large range of grips, fixtures, chambers, video extensometers, protective shields, and other accessories Controller & Software The 8874 is supplied with a two-axis digital 8800 controller that provides full system control, including features such as automatic loop tuning, amplitude control specimen protect, 19-bit resolution across the full range of transducers, and adaptive control technology. It also allows access to WaveMatrix™ dynamic testing software, Bluehill® software for axial static tests, and other application specific software, such as the Low Cycle Fatigue or Fracture Mechanics suite.
