Technical Description: Koganei AFDPG-18
The Koganei AFDPG-18 is the high-power flagship of the flat-type parallel air hand series. Featuring an 18mm bore size, this unit is engineered for applications that require substantial gripping force while demanding a compact, low-profile actuator. It is widely utilized in heavy-duty automated sorting, automotive part handling, and industrial pick-and-place tasks where reliability and mechanical strength are the primary requirements.
Maximum Gripping Force and Rigidity
The AFDPG-18 employs a double-piston architecture that maximizes the effective pressure area. At 0.5 MPa, this gripper generates a powerful theoretical gripping force of 113 N, making it the most capable model in the standard flat series. To manage this force, Koganei has integrated a heavy-duty linear guide system that provides superior resistance to pitch, yaw, and roll moments. This ensures that the parallel fingers remain perfectly aligned even when handling off-center or heavy workpieces.
Key Characteristics
- Model: AFDPG-18.
- Bore Diameter: 18 mm x 2 (Double piston).
- Action: Double Acting Parallel.
- Gripping Force: 113 N (at 0.5 MPa).
- Standard Opening Stroke: 40 mm [1.575 in].

Operational Efficiency and Safety
Despite its power, the AFDPG-18 maintains a slim 30mm height profile. The use of high-grade NBR seals and an aluminum alloy body ensures a service life of several million cycles under standard operating conditions. The unit includes integrated mounting slots for proximity sensors on both sides, enabling the control system to confirm part acquisition with millimetric precision. Its robust construction makes it suitable for high-vibration industrial environments.

Maintenance Insights
The AFDPG-18 is factory-lubricated for life. For optimal performance, ensure the air supply is filtered to 5 microns and moisture-free. In high-cycle applications, the linear guide should be inspected for grease integrity to prevent friction-related wear and maintain the high-speed response characteristic of the series.
