Gripping or clamping device

摘要

A gripping or tensioning device (10) for gripping or tensioning articles, has an electric drive (2), the drive driving a pinion (28) mounted on an output shaft (26) and jaws (12,14) which are coupled for movement with the pinion (28) and can be displaced along a base (18) by means of a jaw guide (80). The jaw guide (80) has bearing rollers (42) in the region between the jaws (12, 14) in such a manner that the rotational axes of the bearing rollers run parallel to the pinion rotational axis (84).
