Selection & Application Guidance

Select suction cups according to product shape, surface condition, material, cup geometry, acceleration, orientation and available vacuum. Theoretical holding force should always be reduced by an appropriate engineering safety factor before determining the working load.

Product Features & Existing Technical Details

  • Food and drug packaging
  • FDA compliant silicone compound
  • Single bellows suction cup offering height compensation
  • Cardboard carton and sheet handling
  • Plastic injection molding
  • Glass, stone and ceramic pick and place
  • Small parts vacuum pick and place
  • Simple push on and pull off fitting connection
  • Temperature Range -40C to +250C / -40F to +482F
  • NOTE - Silicone should not be used on surfaces yet to be painted or glass and decorative stone product

Typical Applications

  • Industrial vacuum pick-and-place
  • Packaging and material handling
  • Machine automation and robotic end-of-arm tooling

Important: Product suitability depends on the actual operating conditions. Confirm dimensions, connections, material compatibility, vacuum or pressure requirements, cycle conditions and any required safety factor before final machine integration.

Estimated Lifting Force at 24"Hg

Theoretical lifting force is calculated from the cup's nominal sealing area at approximately 80% vacuum. At sea level, 80% vacuum corresponds to approximately 11.76 PSI differential pressure.

Lifting Force Calculation

Calculation StepMetricImperial
Nominal Areaπ × (2.5cm radius)² = 19.6cm²π × (0.984in radius)² = 3.04in²
Vacuum Level80% vacuum24"Hg / 11.76 PSI differential
Estimated Theoretical Lift19.6 × 0.8 = 15.7kg3.04 × 11.76 = 35.8lb

Important: Lifting force is theoretical and must not be used as the final working load without an appropriate engineering safety factor. Actual holding force depends on vacuum level, surface condition, porosity, cup orientation, acceleration, leakage and dynamic loading.

Frequently Asked Questions

What should I consider when selecting this suction cup?

Consider cup geometry, product shape, surface condition, material, vacuum level, acceleration, orientation and required safety factor.

Is the listed lifting force the safe working load?

No. Any theoretical lifting-force value must be reduced using an appropriate engineering safety factor and validated under actual application conditions.

Can this cup be used on porous materials?

Performance on porous materials depends on leakage and available vacuum flow. Application testing may be required, and a higher-flow vacuum source or a different handling method may be more appropriate.

How should I confirm material compatibility?

Confirm the cup compound against product temperature, surface finish, chemical exposure and any marking or contamination restrictions.
