Product Overview: Koganei AFDPG-8-JA
The Koganei AFDPG-8-JA is a high-precision, flat-type parallel air hand designed for high-speed automated systems. This model features an 8mm bore and is part of Koganei’s ultra-thin series, designed to provide maximum gripping force in the smallest possible footprint. The «-JA» version is specifically equipped with an open-side stroke adjustment, allowing users to precisely limit the maximum width of the gripper fingers when in the open position. This is a vital feature for applications where space is constrained and the fingers must avoid contact with surrounding machine components.
High Rigidity and Double Piston Technology
Unlike standard grippers, the AFDPG-8-JA utilizes a double piston architecture. By placing two pistons in parallel, Koganei effectively doubles the effective pressure area, providing a theoretical gripping force of 26 N at 0.5 MPa. This power is supported by an integrated linear guide that ensures smooth, high-precision movement with a centering accuracy of ±0.07 mm. This mechanical rigidity makes it ideal for handling electronic components, medical devices, and precision automotive parts.

Advanced Integration and Industrial Design
The AFDPG-8-JA is constructed from a hard-anodized aluminum alloy, offering superior wear resistance and a lightweight mass of only 85g. This low weight reduces the inertia on robotic arms, facilitating faster cycle times. The unit is designed for versatility, featuring mounting threads on three surfaces and compatibility with Koganei’s miniature solid-state sensor switches for real-time position feedback.
