The 5000Nmm Spiral Torsion Spring Torsion Tester is mainly used for torsion spring, scroll spings,and other elastic torque components to do torsion test, torque test, torsional angle test etc. The5000Nmm Spiral Torsion Spring Torsion Tester also can  test  the torque at  a certain torsional angle, or test the torisonal angle at a certain torque. And  The 5000Nmm Spiral Torsion Spring Torsion Tester can also be used for the torsion performance test of other elastic elements and the friction mechanism.
