8874 Axial-Torsion Servohydraulic Fatigue Testing System

25 kN /100 Nm

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.

• Compact tabletop
t servohydraulic fatigue testing
t system – frame requires less
t than 0.4 m² (4.3 ft²) of space

• Designed for both dynamic
t and static testing on a
t variety of materials
t and components
• Choice of hydraulic
t configuration and dynamic
t performance to suit t
tapplication
• Extra-height frame option for
t testing longer load strings

t range of grips, fixtures,
t chambers, video
textensometers,
t protective shields, and
t 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.
