Schunk KGG 80-30 Pneumatic Gripper 0303060:
$300.00

The gripper is pneumatically actuated and operates over a pressure range of approximately 2.5 to 8 bar, with 6 bar nominal operating pressure commonly specified. Its compact pneumatic design provides fast actuation, with published opening and closing times of approximately 0.05 seconds, making the unit well suited to high-cycle automated machinery.

These specifications are consistent with SCHUNK’s published KGG documentation and current product listings for part 0303060.

Mechanical performance

A notable feature of the KGG 80-30 is its combination of compact size and relatively high gripping force. The gripper weighs only about 250 g, while providing up to 130 N of closing force under the specified conditions. This makes it appropriate for robotic end-of-arm tooling and automated fixtures where minimizing moving mass is important.

The maximum recommended finger length is 80 mm. Longer or heavier fingers can increase the bending moments acting on the gripper and may reduce performance or service life. SCHUNK documentation specifies maximum permissible moments of 2 Nm about Mx, 5.5 Nm about My, and 6.3 Nm about Mz, with a maximum axial force of 300 N.

Accuracy and operating environment

The KGG 80-30 has a specified repeat accuracy of 0.02 mm, which makes it suitable for applications requiring consistent positioning of repeatedly handled components. The published specifications give an IP40 protection rating. Temperature specifications vary slightly between historical documentation and reseller listings; SCHUNK\'s older catalog documentation specifies an operating range of approximately -10°C to +90°C, while some current listings give a narrower minimum of +5°C. For an engineering application, the applicable SCHUNK datasheet for the specific production revision should therefore be used.

The unit also appears in SCHUNK documentation with a cleanroom classification of ISO 14644-1 Class 7, although this should be verified against the exact configuration and application requirements before specifying it for a controlled-environment installation.

Typical applications

The SCHUNK KGG 80-30 is particularly suited to:

Robotic pick-and-place systems
Automated assembly machines
Small-part handling
Machine tending
Packaging and sorting equipment
Component loading and unloading
Transfer systems
Automated production fixtures
General pneumatic gripping applications

Because it is a parallel gripper, the jaws move linearly toward and away from one another. This makes it useful when the workpiece must be positioned accurately and held along defined gripping surfaces. Interchangeable or application-specific fingers can be attached to the base jaws to accommodate the geometry of the workpiece.

Overall description

In summary, the SCHUNK KGG 80-30, 0303060 is a compact, high-speed, two-finger pneumatic parallel gripper for small-component automation. Its 15 mm stroke per jaw, 130 N closing force, 0.02 mm repeat accuracy, and approximately 50 ms opening/closing time make it a practical choice for fast and repeatable industrial handling operations. Its small 80 × 26 × 41.3 mm envelope and 0.25 kg weight are particularly advantageous when it is mounted on a robot or compact automated mechanism.

Part identification: SCHUNK KGG 80-30, OEM part number 0303060. SCHUNK\'s own CAD catalog lists 0303060 as the KGG 80-30 model.
