Gripper Sizing — Robot Tool Changer
Holding-force and sizing math for a robot tool changer including acceleration and safety factor.
Tool changers fail at the moment rating, not the payload line — a light tool with a long CG beats a heavy compact one for abuse. Size against the worst TOOL+PART combination mid-move; the catalog's static kg number is the least informative spec on the page.
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 — Robot Tool Changer
Gripper Sizing — Robot Tool Changer computes the governing relationship M = m(g+a)·SF × d_CG · F_z = m(g+a)·SF live as you type. Tool changers fail at the moment rating, not the payload line — a light tool with a long CG beats a heavy compact one for abuse. Size against the worst TOOL+PART combination mid-move; the catalog's static kg number is the least informative spec on the page. 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 — Robot Tool Changer
- 1Enter your values — Heaviest tool + part, CG offset from flange, Peak acceleration, Safety factor (sensible defaults are pre-filled).
- 2Read the live results: Design moment at changer, Axial design load.
- 3Check the "with your numbers" line to see M = m(g+a)·SF × d_CG · F_z = m(g+a)·SF substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Gripper Sizing — Robot Tool Changer?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula M = m(g+a)·SF × d_CG · F_z = m(g+a)·SF with authoritative sources cited on the page (Schmalz — Vacuum handling calculation basics; Monkman et al., Robot Grippers (Wiley-VCH))
- ✓Tool changers fail at the moment rating, not the payload line — a light tool with a long CG beats a heavy compact one for abuse.
- ✓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 — robot tool changer use?+
It evaluates M = m(g+a)·SF × d_CG · F_z = m(g+a)·SF, 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?+
Tool changers fail at the moment rating, not the payload line — a light tool with a long CG beats a heavy compact one for abuse. 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 robot tool changer including acceleration and safety factor. A free industrial robot kinematics & cell design tool. Size against the worst TOOL+PART combination mid-move; the catalog's static kg number is the least informative spec on the page. 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.
