Position
l A double acting piston is connected by a shaft to a double sided pin wedge.
l The pin wedge slides in a hole located in each of the jaws converting vertical
motion of the wedge into horizontal synchronous motion of the jaws.
l This gripper is suitable for internal or external gripping.
Unit has top manifold ports.
G
Fingers attach to jaws with screws and
locate with dowel pins or by keying.
