AXIAL TORSION SYSTEMS

The best solution for tensile and torsion testing. BV systems are available in a wide range of loads, with torque capacities up to 230 Nm, the compact design requires minimal space and offers a high level of rigidity and alignment. The torsional motor is coupled to every linear actuator series we manufacture, from electromechanical actuators, EA series and all UD, HUD and XUD series based on linear motors.
