VFB40CSG | 43mm single-bellows Vacuforce suction cup — bright-green conductive silicone

Vacuforce VFB40CSG is a 43mm single bellows suction cup made from bright-green conductive silicone. Its single-bellows profile is intended for industrial vacuum pick-and-place; selection depends on the part surface, cup geometry, available vacuum and mounting connection. The bright-green conductive silicone targets electronics handling; electrical performance requires application validation.

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.

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

  • Electronic components and sensitive assembly handling
  • Automated transfer of suitable electronic housings and components
  • Vacuum end-of-arm tooling with validated electrical controls
  • Height compensation over modest part variation

Why Choose This Cup Style?

Single 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 — VFB40CSG

The -CSG material is bright-green conductive silicone designed for handling electronic components. Electrical resistance and suitability for an ESD control programme must be verified for the actual assembly.

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 VFB40CSG mean, including its material suffix?

VFB40CSG identifies a Vacuforce 43mm single bellows cup. The material designation -CSG refers to bright-green conductive silicone. The -CSG material is bright-green conductive silicone designed for handling electronic components. Electrical resistance and suitability for an ESD control programme must be verified for the actual assembly.

What colour is the VFB40CSG suction cup?

This model is supplied in bright green.

What applications suit this single-bellows suction cup?

Typical uses include Electronic components and sensitive assembly handling, Automated transfer of suitable electronic housings and components. 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 43mm (1.693in). 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 VFB40CSG provide?

At the page calculation condition of approximately 24inHg (80% vacuum), the existing estimate is 11.6kg / 26.5lb 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 the conductive silicone independently certified ESD-safe?

This cup uses conductive silicone for electronic-component handling; no surface-resistance or ESD certification figure is stated in this listing. Verify electrical properties, grounding and ESD process requirements before use.

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.
