Gripper Sizing — 2-Finger Parallel Gripper (Friction Grip)
Holding-force and sizing math for a 2-finger parallel gripper (friction grip) including acceleration and safety factor.
Friction gripping multiplies every sin: smooth jaws at µ=0.25 need 8× the part's apparent weight in grip force once acceleration and safety factor stack. The pad comparison output makes the cheapest upgrade obvious — µ is the lever, not a bigger gripper.
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 — 2-Finger Parallel Gripper (Friction Grip)
Gripper Sizing — 2-Finger Parallel Gripper (Friction Grip) computes the governing relationship F_grip = m(g+a)·SF / (2µ) — two friction surfaces live as you type. Friction gripping multiplies every sin: smooth jaws at µ=0.25 need 8× the part's apparent weight in grip force once acceleration and safety factor stack. The pad comparison output makes the cheapest upgrade obvious — µ is the lever, not a bigger gripper. 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 — 2-Finger Parallel Gripper (Friction Grip)
- 1Enter your values — Part mass, Peak acceleration, Jaw–part friction µ, Safety factor (sensible defaults are pre-filled).
- 2Read the live results: Required grip force, With rubber pads (µ=0.6).
- 3Check the "with your numbers" line to see F_grip = m(g+a)·SF / (2µ) — two friction surfaces substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Gripper Sizing — 2-Finger Parallel Gripper (Friction Grip)?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula F_grip = m(g+a)·SF / (2µ) — two friction surfaces with authoritative sources cited on the page (Schmalz — Vacuum handling calculation basics; Monkman et al., Robot Grippers (Wiley-VCH))
- ✓Friction gripping multiplies every sin: smooth jaws at µ=0.25 need 8× the part's apparent weight in grip force once acceleration and safety factor stack.
- ✓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 — 2-finger parallel gripper (friction grip) use?+
It evaluates F_grip = m(g+a)·SF / (2µ) — two friction surfaces, 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?+
Friction gripping multiplies every sin: smooth jaws at µ=0.25 need 8× the part's apparent weight in grip force once acceleration and safety factor stack. 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 2-finger parallel gripper (friction grip) including acceleration and safety factor. A free industrial robot kinematics & cell design tool. The pad comparison output makes the cheapest upgrade obvious — µ is the lever, not a bigger gripper. 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.
