General notes about the series
Closing moment
is the arithmetic sum of the individual moment applied to each jaw.
Finger length
is measured from the reference surface as the distance P in direction to the main axis.
Repeat accuracy
is defined as a distribution of the end Position for 100 consecutive strokes.
Workpiece weight
is calculated for force-fit gripping with a coefficient of static friction of 0.1 and a safety factor of 2 against workpiece slippage at acceleration due to gravity g. For form-fit or capture gripping, there are significantly higher permissible workpiece weights.
Closing and opening times
are movement times of the base jaws only, without application-specific gripper fingers. Valve switching times, hose fill times, or PLC reaction times are not included, and are to be considered when cycle times are calculated.
