GRIP GIS Internal Gripper Short Review: Specs, Price and Applications
The GRIP GIS is a shorter variant of the GI internal gripper with a specially designed gripping zone for more demanding applications. Inserted into a bore, it expands a silicone membrane under pneumatic pressure and grips by friction.
Its modified gripping zone lets it reach deeper into a borehole, which is particularly useful for complex or heavier parts.
Quick Verdict
The GI's tougher sibling: compact, yet able to grip deeper and handle heavier parts.
GRIP GIS Internal Gripper Short at a Glance
Specification | Details |
Gripper type | Pneumatic internal gripper, short |
Element | Silicone membrane |
Gripping zone | Modified for deeper bore reach |
Principle | Friction against bore wall |
Applications | Complex or heavier parts |
Price | Request a quote |
Design and Operating Principle
Gripping deeper in a bore gives better leverage against tilting, which matters for heavier or longer parts.
The short body keeps the tool compact and reduces the moment on the robot.
Like the GI, it avoids marking the part by spreading contact over the membrane.
Integration and Selection
Match the gripper to the bore diameter and depth, and test holding force with production parts.
Use GI for shallow bores and GIS for deeper or heavier applications.
