Pneumatic gripper / parallel / 2-jaw
Number of jaws:
The pair of ground, stainless steel guide shafts, are press fit and pinned to each of the gripper jaws. In addition to this, the shafts are normally placed diagonally, spaced far apart, which ensures maximum jaw stability. At the same time, there are only three moving parts, while the jaw units can be linked by the third moving part, which is a rocker arm that can synchronize the jaw motion. Note that the arm does not drive the jaw, which means the wear is minimal.
At the same time, the pistons and shaft of each jaw can pass freely through enlarged holes in its mate. The "C" in the photos points to the opposing piston faces to which pressure is applied for jaw closing. Next, "O" targets the opposing jaw open faces, while the cylinder blocks are symmetrical and the four cylinders are bored in each of the two blocks, connected by internal air passages.
