Yunker vibration test according to DIN65151 / DIN25151
There is a Junker vibration test according to the German industrial standard DIN65151 (or DIN25151). It is said to be the world's most rigorous vibration test conducted under the worst conditions for bolt joints. The clamping axial force refers to the force that remains in the fastener after the applied clamping torque has been lost due to friction resistance at the bolt/nut bearing surface and the threaded part; it is the force that the fastener exerts during tightening. This axial force sensor allows the Junker vibration test to determine how much axial force is lost due to vibration and to identify and establish the point at which the axial force is completely lost. We have a demo unit of the J160, so please feel free to contact us.
