Pneumatic Gripping Unit (Parallel Gripping Unit PGM)
As our gripping units are made of high-strength aluminum (hard anodized), matched with grinded stainless steel guiding-elements, we deliver a resistant robust construction. We do achieve a repeat accuracy of +/- 0.02 mm. The variety of gripping units allows to cover a wide range of strokes from 4 to 30 mm (2 – 15 mm each jaw) and includes small units. Jaw positions of PGM can be monitored witch inductive proximity switches and (from series PGM-60 onwards) also with magnetic field sensors. Centering rings are included with our gripping units PGM for easy, precise and clearance free connections.
Yes! All our units do work inbetween a range of 4 and 8 bar. Stated technical data are valid at 6 bar. PGM–Grippers even work at 2 up to 8 bar.
These types of PGM-gripper are available in variants N (normal), Ö (high opening force) and S (high closing force). PGM-Models Ö or S cover application-jobs if higher forces are needed for clamping or retention – also see gripper-brochure.
