Long Stroke Gripper Offers Efficient Alternative
March 15, 2012
When components of different sizes have to be handled alternately, conventional centric grippers quickly reach their limits. In order to cover the whole spectrum of components, gripper fingers or complete grippers have to be exchanged over and over again. Schunk offers a highly efficient alternative: the innovative Long Stroke Gripper PZH-plus. Its patented multi-tooth guidance and its housing made of high strength aluminum assure a very compact performance. Optionally, the PZH-plus can be reliably monitored via magnetic field sensors or inductive sensors. The large center bore allows the installation of a camera, a feed-through of material, or the gripping of very long workpieces. The Long Stroke Centric Gripper comes in four sizes. At a weight between 1.6 and 33 kg, the maximum stroke per finger amounts between 20 and 75 mm, and the gripping forces between 250 and 3.800 N. The gripper is suitable for ID and OD gripping of workpieces weighing up to 19.3 kg.
