VFBL30-2N | 30mm multi-bellows Vacuforce suction cup — nitrile rubber (NBR)

Name: VFBL30-2N
Brand: Vacuforce
Price: 9.10 USD
Availability: InStock

Vacuforce VFBL30-2N is a 30mm multi bellows suction cup made from nitrile rubber (NBR). Its multi-bellows profile is intended for industrial vacuum pick-and-place; selection depends on the part surface, cup geometry, available vacuum and mounting connection.

This page includes calculated theoretical lifting force at 24"Hg / 80% vacuum using both metric and imperial engineering methods.

Estimated Lifting Force at 24"Hg

Lifting force is calculated from the suction cup diameter and adjusted to 80% vacuum. At sea level, atmospheric pressure is approximately 14.7 PSI. At 80% vacuum, the effective pressure is 14.7 x 0.8 = 11.76 PSI.

Lifting Force Calculation

Calculation Step	Metric	Imperial
Diameter	30mm / 3.00cm	1.181"
Area	π x 1.50² = 7.1 cm²	π x 0.591² = 1.10 in²
Vacuum Level	80% vacuum	24"Hg / 80% vacuum
Effective Pressure	Area x 0.8	14.7 PSI x 0.8 = 11.76 PSI
Estimated Lifting Force	7.1 x 0.8 = 5.7 kg	1.10 × 11.76 = 12.9 lb

Important: Calculated lifting force is theoretical and should not be used as the final working load without applying the correct safety factor. Actual performance depends on surface condition, porosity, acceleration, cup orientation, leakage, vacuum level and application conditions.

Typical Applications

General industrial pick-and-place
Handling suitable cartons, glass, plastics and formed parts
Vacuum tooling and assembly automation
Additional bellows compliance for varying part elevations

Why Choose This Cup Style?

Multiple Bellows suction cups are selected according to product shape, surface condition, required height compensation and cycle speed. Bellows styles provide more compliance and height compensation, while flat cups are generally preferred where low internal volume and fast release are important.

Material and colour — VFBL30-2N

General-purpose NBR for industrial handling. Select according to surface, temperature, oil exposure and application conditions.

Cup selection and fit considerations

Compare cup diameter, bellows profile, lip geometry, mounting bore, material and vacuum performance when selecting a functional alternative. A similar appearance or nominal model size does not by itself guarantee interchangeability.

Frequently Asked Questions

What does VFBL30-2N mean, including its material suffix?

VFBL30-2N identifies a Vacuforce 30mm multi 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.

What colour is the VFBL30-2N suction cup?

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

What applications suit this multi-bellows suction cup?

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.

What is the cup size and how should I select a fitting?

The listed cup diameter is 30mm (1.181in). Match the fitting to the Vacuforce cup series and mounting bore; a shared nominal size is not proof of mounting compatibility.

How much theoretical lifting force does VFBL30-2N provide?

At the page calculation condition of approximately 24inHg (80% vacuum), the existing estimate is 5.7kg / 12.9lb before any safety factor. This assumes ideal sealing and must not be treated as a certified working load.

Does a similarly shaped cup automatically fit another brand of tooling?

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.

Is this NBR cup metal-detectable or food-contact silicone?

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.

Is a safety factor required for vertical lifting?

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.
