■How to design externalfingers to maximizedust-resistance ability

"Wish the Body Was a Little Thinner..." Is Finally Responded

■Very thin bodyInternal cylinders are located on the side toward workpiece, andwhich makes the motion of the cylinders parallel to jaw. Thesechanges reduces thickness of the gripper by a half for use inconfined spaces.

■Simple structureDirect drive mechanism to minimize hooking problem instead ofworm drive mechanism. Motion failure caused by lack of greasecan be also minimized.
