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.
Large diameter hollow columns increase stiffness and resonant frequency offering better performance
Adjustable, widely spaced cam follower bearings minimize backlash and crosstalk between the load and torque axes
Proprietary transducer design provides high stiffness and sensitivity with low crosstalk
Patented axial/torsional coupler enables precise concentric and angular alignment
