Two jaws parallel stroke grippers VRG
The VRG range of parallel grippers has the ability to clamp the work piece both internally and externally and offer the following advantages :
°
Five dimensions with three versions of stroke for each model.
°
They allow for gripping heavy weights and variably sized parts.
°
The double piston construction results in a high gripping force with reduced dimensions.
°
Finger motion synchronization by a rack- and pinion mechanism.
°
Shaft equipped with self lubricated bearings and with dirt protected seals.
°
Grooves in the body allow the proximity switches introduction.
