Schunk Develops A New Benchmark In The Field Of Grippers

8 July 2015

For many years, the SCHUNK PGN-plus universal gripper has been considered a benchmark for gripping modules. With the new PGN-plus Permanent, SCHUNK, the competence leader for clamping technology and gripping systems is raising the bar.

Its unique permanent lubrication provides a faster and more even distribution of the lubricant, even with short strokes. The complete contour of the patented multi-tooth guidance is equipped with grease pockets, which ensures a continuous supply of lubricant. This princi-ple of the minimal quantity lubrication increases the already great life span of the SCHUNK best sellers.

Consistent supply of lubricant

“SCHUNK PGN-plus Permanent is a robust and perennial gripper, which reduces operating costs and offers a better performance than our current flagship PGN-plus. It ensures an excellent repeat accura-cy of 0.01 mm, and ensures the implementation of particularly effi-cient systems,“ said Dr. Markus Klaiber, CTO at SCHUNK. It is equipped with an oval piston drive like its predecessor to ensure high forces in confined spaces. SCHUNK underlines the extraordinary performance of this universal gripper with a unique 30-year functional warranty, which is second to none on the market.

Fully compatible with the PGN-plus

The SCHUNK PGN-plus Permanent seamlessly integrates into the PGN-plus family. Nearly the whole range of possible automatic appli-cations can be process-reliably controlled with the universal gripper. This covers applications from machine/system loading in the metal cutting industry and foundries to assembly applications in the auto-motive and electrical industry through to delicate handling tasks in the medical and pharmaceutical industry. The PGN-plus family has been successfully used in applications with high temperatures, pollution and aggressive media as well as in clean rooms and explosive environments.

On request, the modules are available with a spring lock for mechanical gripping force maintenance that combines with compensation units for compensating angle errors. Moreover, a broad sensor program comprising of inductive proximity switches, magnetic switches and position sensors is available. Instead of many isolated applications, users reduce their internal coordination efforts by using the universal modular gripping system.
