This machine tests the fatigue strength of metals or other materials under bending and rotating conditions.

ModelPQ-6 typically tests the bending fatigue limitδ-1 of metals under the action of a symmetrical repeatedly alternating bending force.

Accordingly the tension-compression fatigue limit δ-1p and torsion fatigue limitτ-1 can be determined by calculation according to experienced formula.

The system has simple structure, easy to operate, stable and reliable liable.

The unit is used in industrial environments and in educational institutions.
