Jaw

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.
