Schmalz GmbH PFYN-80-NBR-55-G1 4-AG Suction Cup

PFYN-80-NBR-55-G1/4-AG is a flat, round suction cup from Schmalz designed for automated material handling on smooth to slightly rough surfaces. With an 80 mm diameter, the elastomer is nitrile rubber (NBR) and has a Shore A hardness of 55, delivering durable sealing and reliable grip across a range of parts. The external connection is a G1/4-AG thread, enabling compatibility with standard Schmalz nipple assemblies and many vacuum systems; at this size the unit is delivered unassembled (elastomer element and connection nipple shipped separately). The cup’s internal cavity volume is about 25 cm3 and it can generate a theoretical suction force of 260 N under -0.6 bar vacuum on a dry, smooth surface; a 6 mm hose inner diameter is recommended for the air supply line. The PFYN family is noted for flat, round cups that tolerate slight surface irregularities, and the minimum convex workpiece radius is 150 mm, which informs how curved the surface can be before the cup loses contact. Overall, PFYN-80-NBR-55-G1/4-AG provides a robust, chemically compatible grip for automated handling tasks on production lines where Schmalz vacuum components are employed.
