Gripper Sizing — Flat Vacuum Cups (Horizontal Lift)
Holding-force and sizing math for a flat vacuum cups (horizontal lift) including acceleration and safety factor.
Cup-down lifting is vacuum's easy case — the pad fights weight directly. The trap is the acceleration term: a 'gentle' 1 g stop doubles the needed force, which is why catalogs derate cups to half their static rating for dynamic handling.
Formula
Note: Planning-level engineering estimate — final robot selection, guarding layout and risk assessment must follow the integrator's calculations and a documented ISO 12100/10218 risk assessment.

About Gripper Sizing — Flat Vacuum Cups (Horizontal Lift)
Gripper Sizing — Flat Vacuum Cups (Horizontal Lift) computes the governing relationship F = m(g+a)·SF/n · D = 2√(F/(ΔP·π)) live as you type. Cup-down lifting is vacuum's easy case — the pad fights weight directly. The trap is the acceleration term: a 'gentle' 1 g stop doubles the needed force, which is why catalogs derate cups to half their static rating for dynamic handling. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Gripper Sizing — Flat Vacuum Cups (Horizontal Lift)
- 1Enter your values — Part mass, Peak acceleration, Vacuum level, Number of cups and more (sensible defaults are pre-filled).
- 2Read the live results: Force needed per cup, Min cup diameter.
- 3Check the "with your numbers" line to see F = m(g+a)·SF/n · D = 2√(F/(ΔP·π)) substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Gripper Sizing — Flat Vacuum Cups (Horizontal Lift)?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula F = m(g+a)·SF/n · D = 2√(F/(ΔP·π)) with authoritative sources cited on the page (Schmalz — Vacuum handling calculation basics; Monkman et al., Robot Grippers (Wiley-VCH))
- ✓Cup-down lifting is vacuum's easy case — the pad fights weight directly.
- ✓SI ⇄ Imperial toggle converts your inputs in place, so you can work in the units your drawings use
Frequently asked questions
What formula does the gripper sizing — flat vacuum cups (horizontal lift) use?+
It evaluates F = m(g+a)·SF/n · D = 2√(F/(ΔP·π)), exactly as published. Sources: Schmalz — Vacuum handling calculation basics; Monkman et al., Robot Grippers (Wiley-VCH). The substituted worked example on the page lets you verify every step against the textbook.
How should I read the result — and how far can I trust it?+
Cup-down lifting is vacuum's easy case — the pad fights weight directly. Planning-level engineering estimate — final robot selection, guarding layout and risk assessment must follow the integrator's calculations and a documented ISO 12100/10218 risk assessment.
When is this calculator the right tool for the job?+
Holding-force and sizing math for a flat vacuum cups (horizontal lift) including acceleration and safety factor. A free industrial robot kinematics & cell design tool. The trap is the acceleration term: a 'gentle' 1 g stop doubles the needed force, which is why catalogs derate cups to half their static rating for dynamic handling. For neighbouring scenarios, the related tools below cover the same engine with different presets.
Does it support both metric and imperial units?+
Yes — the SI ⇄ Imperial toggle converts the values already in the fields, preserving the physical quantity, so you can flip mid-calculation without re-entering anything.
