FGA Series Double-Layer Vacuum Suction Cups
Double-layer vacuum suction cups and compatible aluminum fittings for industrial automation, robotic handling, and vacuum systems. Available in blue and white silicone or black nitrile rubber, with model-specific product views and dimensional drawings.
- Models: FGA-11 through FGA-78
- Materials: silicone and nitrile rubber
- Compatible aluminum fittings are included as selectable variants
FGA fitting groups by listed cup model
FGA cup options and fitting options are separately selectable. Start with the cup's full size and material label, then use the fitting group shown for that cup.
| Cup group stated on fitting labels | Fitting choices listed |
|---|---|
| FGA-11 to FGA-25 | ZPT2-A5, ZPT2-B5, G1/8-AG or G1/8-IG |
| FGA-33 to FGA-63 | G1/8-AG, G1/4-AG or G1/4-IG |
| FGA-78 | Large G1/4-AG or Large G1/4-IG |
Use the fitting's own drawing to check cup retention and mounting dimensions. A shared G1/4 thread designation does not prove that the standard and Large fittings have the same cup interface.
Applications and Suitable Workpieces
FGA Series Double-Layer Vacuum Suction Cups & Fittings: Bellows suction cups provide vertical stroke, damping and contour adaptation for parts with height variation, curvature or sensitive surfaces.
Recommended applications
- Curved or slightly uneven plastic parts, cartons, packaged goods, formed panels, glass and general industrial components.
- Mold unloading, machine tending, sorting, assembly and robotic pick-and-place where gentle contact is required.
- Multiple-cup grippers handling parts with small differences in height or position.
Model and selection notes
- FGA11 through FGA78 identify diameter. Blue/white silicone and black NBR versions have different material behavior; fittings are selected by cup size and thread.
- More bellows layers provide greater stroke and height compensation but can allow more lateral movement; select the profile for the required stability.
- Use the exact model dimensions and thread configuration shown in the product image when matching an existing holder.
- Holding force depends on sealing area, vacuum level, surface condition, acceleration and safety factor; test the actual workpiece.
