SCHUNK  (www.schunk.com) has expanded its portfolio of modular long-stroke electric grippers with the addition of the LEG 400. Equipped with a servo motor, this weight reduced gripper offers a variable stroke ranging from zero to 103 mm and a gripping force of up to 1050 N, making it suitable for automotive and metal cutting industry.

The new LEG gripper features a design based on the modular principle. With only one motor, the gripper weighs 6.5 kg and can be fitted with an electric and pneumatic drive. The gripper also allows users to choose their preferred servo motor. Thus, robot manufacturers can utilize their own motors, enabling them to control the gripper with similar set of commands featured in a robot. Moreover, the applicable forces can be controlled and measured with servo-electric drives. When operated with one servo motor, the gripper’s fingers move synchronously while both its drive spindles are coupled. On the other hand, operating the LEG with two motors allows the fingers to move freely and independently within the gripping range.

With the slides and guided slides, as well as the connecting components and supporting lateral cheeks offered in different versions and sizes, the LEG gripper can be adapted economically to its corresponding load and task. Its optional image or sensors processing system makes the gripper a sensitive tool in the assembly, production and packaging processes. Its change system can be utilized to alter the fingers automatically or manually offers the user with added flexibility. The reduced weight of the gripper allows it to deliver excellent acceleration and remarkable speeds, resulting to higher overall power and shorter cycle times.
