Gripper Sizing — Vacuum Cups in Shear (Vertical Panel)
Holding-force and sizing math for a vacuum cups in shear (vertical panel) including acceleration and safety factor.
Carrying glass or sheet vertically, the cup holds by friction alone — needed force jumps 1/µ-fold and the standard safety factor doubles to 4. This is why window-handling rigs look absurdly over-cupped to anyone who only sized horizontal picks.
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 — Vacuum Cups in Shear (Vertical Panel)
Gripper Sizing — Vacuum Cups in Shear (Vertical Panel) computes the governing relationship F_normal = m(g+a)·SF/(n·µ) — the cup holds by friction only live as you type. Carrying glass or sheet vertically, the cup holds by friction alone — needed force jumps 1/µ-fold and the standard safety factor doubles to 4. This is why window-handling rigs look absurdly over-cupped to anyone who only sized horizontal picks. 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 — Vacuum Cups in Shear (Vertical Panel)
- 1Enter your values — Panel mass, Peak acceleration, Vacuum level, Number of cups and more (sensible defaults are pre-filled).
- 2Read the live results: Normal force per cup, Min cup diameter.
- 3Check the "with your numbers" line to see F_normal = m(g+a)·SF/(n·µ) — the cup holds by friction only substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Gripper Sizing — Vacuum Cups in Shear (Vertical Panel)?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula F_normal = m(g+a)·SF/(n·µ) — the cup holds by friction only with authoritative sources cited on the page (Schmalz — Vacuum handling calculation basics; Monkman et al., Robot Grippers (Wiley-VCH))
- ✓Carrying glass or sheet vertically, the cup holds by friction alone — needed force jumps 1/µ-fold and the standard safety factor doubles to 4.
- ✓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 — vacuum cups in shear (vertical panel) use?+
It evaluates F_normal = m(g+a)·SF/(n·µ) — the cup holds by friction only, 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?+
Carrying glass or sheet vertically, the cup holds by friction alone — needed force jumps 1/µ-fold and the standard safety factor doubles to 4. 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 vacuum cups in shear (vertical panel) including acceleration and safety factor. A free industrial robot kinematics & cell design tool. This is why window-handling rigs look absurdly over-cupped to anyone who only sized horizontal picks. 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.
