SWG 20

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.

Operating principle
double-acting, guided kinematics

Housing material
Aluminum alloy, anodized

Base jaw material
Aluminum alloy, anodized
