Gripper| Parallel 2 jaws |CH73-DO

Parallel type Small Gripper, stroke from 6 to 10mm

This thin type gripper has synchronized fingers for opening and closing operations thanks to a cam guided by a roller. Consequently, these grippers allow accurate operations even when long attachments are mounted.

They can be mounted with the available tappered holes or with a dedicated mounting support allowing easy adjustment and positionning.

Our wide range of 2-jaws parallel grippers can be used for chucking extremely small parts to biggest ones. Indeed, NKE 2-jaws grippers are available in various sizes, gripping forces and strokes.
