General notes about the series

Gripping force
is the arithmetic sum of the individual force applied to each jaw at distance P (see illustration).

Finger length
is measured from the reference surface as the distance P in direction to the main axis.

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.

Repeat accuracy
is defined as a distribution of the end Position for 100 consecutive strokes.

Closing, opening and swiveling times
Closing and opening times are movement times of the base jaws only, without application-specific gripper fingers. Swivel times are the pure movement timesof the rotating part. Valve switching times, hose fill times, or PLC reaction times are not included, and are to be considered when cycle times are calculated.

Middle attached load
intended to represent a typical load. It is defined as the half of the max. possible mass moment of inertia that can be swiveled without restriction, bouncing or hitting, with a centric load and a vertical rotating axis.

Operating principle
Combined rotor and piston drive

Base jaw material
Steel

Actuation
pneumatic, with filtered compressed air as per ISO 8573-1:2010 [7:4:4].

Warranty
24 months

Scope of delivery
Centering sleeves, O-rings for direct connection, screws for lateral fastening, steel balls for adjustment of the swiveling angle, assembly and operation manual with declaration of incorporation

Gripping force maintenance
possible by using the version with mechanical gripping force maintenance or pressure maintenance valve SDV-P
