Series 809 Axial/Torsional Test Systems
Apply simultaneous axial and torsional loads and displacements to a wide array of specimens. This highly versatile test system is capable of everything from static testing to multiaxial fatigue characterization and offers superior stiffness for increased accuracy.
Applications
Static Testing
Dynamic Testing
Test Specimens
Metals
Composites
Plastics
Key Product Features
High Performance
Large diameter hollow columns increase stiffness and resonant frequency offering better performance
Accurate
Adjustable, widely spaced cam follower bearings minimize backlash and crosstalk between the load and torque axes
Innovative Technology
Proprietary transducer design provides high stiffness and sensitivity with low crosstalk
Precise
Patented axial/torsional coupler enables precise concentric and angular alignment
