The fatigue tester tests a spring under similar working conditions.
The tester has 6 stations in which springs can be tested. The springs are compressed and relaxed with the predefined speed and testlength. If one spring breaks the tester is stopped and the number of cycles is shown on the counter-display.

The maximum number of cycles can be predefined.

Technical data:
max. height of stroke : 120 mm
Motor torque: 150 Ncm
Reduction: 1 : 12
max. cycles: 10.000.000
Speed: max. 12 rps

With the fatigue tester the fatigue durability of a spring can be tested. The tester has 4 positions for springs where 2 springs can be inserted which are stressed until the maximum cycles are reached or the spring got a fatigue fracture. With a presetable counter the maximum cycles are programmed. When one spring is damaged the tester stops and on the counter the reached number of cycles is displaied.
