Technical Description: Koganei AFDPG-8-JB
The Koganei AFDPG-8-JB is a premium, 8mm bore flat-type parallel air hand designed for precision industrial gripping. This model is distinguished by the «-JB» suffix, which denotes a closed-side stroke adjustment mechanism. This mechanical end-stop allows the operator to control exactly how far the fingers close, which is essential for handling fragile or soft workpieces that could be damaged by full-force compression. By limiting the stroke, you ensure a consistent, safe grip every time.
Precision Linear Guide and Performance
The AFDPG-8-JB incorporates a high-accuracy linear guide system that eliminates finger deflection and ensures high repeatability. The parallel gripping action is synchronized by an internal rack-and-pinion mechanism, providing perfectly balanced movement. Despite its thin 18mm height, the double-piston design allows it to generate a gripping force of 26 N, making it a powerful solution for robotic end-of-arm tooling (EOAT) in the electronics and semiconductor industries.

System Reliability and Speed
Weighing under 100 grams, the AFDPG-8-JB minimizes the payload on high-speed robotic systems, allowing for higher accelerations. The unit features integrated slots for mounting proximity sensors on either side of the body. The hard-anodized finish protects the aluminum body against the rigors of high-cycle industrial operation, while the stainless steel guide rails ensure that the gripper maintains its ±0.07mm repeatability over millions of cycles.

Maintenance Insights
The AFDPG-8-JB is designed for low-maintenance operation. However, in environments with high particulate counts, it is recommended to inspect the linear guide periodically for debris. Using 5-micron filtered air is essential to protect the internal seals and maintain the high-speed response time of the double-piston assembly.
