4.7.3 Checking and Adjusting the Belt Tension
[1] Checking the Tension
As a guideline, belt tension is evaluated by the load needed to deflect the belt by 10mm when the
belt is pushed near the stroke center.
The table below lists the appropriate loads needed to achieve a 10mm deflection on each belt used
at different strokes.
If the measured load is less than the applicable value by approx. 20% or more, the belt is loose
and its tension must be adjusted.
