VFDB40N identifies a Vacuforce 40mm double bellows cup. The material designation -N refers to nitrile rubber (NBR). General-purpose NBR for industrial handling. Select according to surface, temperature, oil exposure and application conditions.

The current product data identifies NBR material but does not specify a reliable standard colour; confirm colour against the ordered product.

Typical uses include General industrial pick-and-place, Handling suitable cartons, glass, plastics and formed parts. Confirm surface sealing, process conditions, cycle rate and handling orientation by testing.

The listed cup diameter is 40mm (1.575in). Match the fitting to the Vacuforce cup series and mounting bore; a shared nominal size is not proof of mounting compatibility.

At the page calculation condition of approximately 24inHg (80% vacuum), the existing estimate is 10.1kg / 22.9lb before any safety factor. This assumes ideal sealing and must not be treated as a certified working load.

No. Compare actual lip diameter, bellows geometry, mounting interface, material and working conditions before selecting a fit-form-function alternative. Confirm performance by application testing.

No. -N identifies general-purpose nitrile rubber. Metal-detectable grades use -SMI/-STMI and standard FDA-compliant silicone grades use -S/-ST; select material based on the application.

Yes. Use an appropriate engineering safety factor; Vacuforce normally recommends at least 8:1 for vertical lifting. Account for leakage, part acceleration, load orientation and surface condition, and validate safe working load in the application.
