SEAM FATIGUE TESTER SPECIFICATIONS
Control of the stroke length:
We have a gage bar that can be set on the moving jaws to set the stroke length of the sample.
Please see the picture below
You can see the measurements on the gage that can be set for the samples that you have. This
gage then rests on two locator pins on top of the machine. The gage is designed to meet the
standard dimensions of our customer’s specifications (GM, Ford, Nissan, and Toyota).
Jaws and jaw width:
You can see from the picture below that there are four jaws. Two are mounted on the center
moving portion of the tester, and they are fixed on those positions. There is one to the left and
one to the right. The width of these jaws is 90 mm to meet the widest requirement of our
customers. Please see the picture below.
You can use all or a portion of the width of these jaws as your test requires. The clamping
mechanism (which works with the knob to compress the sample across the entire width) is easy
to operate with a large knob to give you lots of force to open or tighten the clamp.
Adjustable Shelf Height:
At the ends of the tester are the arms that allow you to raise or lower the shelf height (the
shelves are inside the tester cabinet and not readily visible).
These arms can be lowered to meet the GM test requirement. To lower these arms you will
need to loosen the clam around BOTH of the ends of this handle. To do this, you need to
slightly loosen each of the three screws on each of the handles. DO NOT TAKE THEM OUT OR IT
MAY BE DIFFICULT TO RE-ASSEMBLE. Once you have loosened these clamps, the arm will lower
for the GM test. Reverse the process to return the arms to the upright position. See the photo
below for the set screws .
Set Screws: see above
Mass Weight
The mass of our weight is 3kg. We measure this to +/- 2 grams, so the accuracy is very good.
Also, we have reduced the weight of the clamping mechanism as this could have an impact on
the test results.
