Use the Moment of Inertia Calculator for Pneumatic Motion to calculate combined inertia of common load shapes for rotary actuator sizing. The calculator uses Mass elements (kg, radius m) — one per line and reports individual/combined inertia; center-of-gravity support values.
Read the result in the context of the selected units and pressure basis. For this tool, the primary outputs are individual/combined inertia; center-of-gravity support values. Change one input at a time when comparing scenarios so the effect of each variable remains clear.
PneumaForge applies this verified method: Standard rigid-body inertia + parallel-axis theorem. The functional engine is shared with related tools in the inertia family, while this page solves the specific intent represented by pneumatic moment of inertia calculator.
Standard rigid-body inertia + parallel-axis theoremReproducible example: start with the calculator's default values (Mass elements (kg, radius m) — one per line = 2,0.5\n1,0.2) and calculate the result. Then change the variable most relevant to your application and compare the new individual/combined inertia; center-of-gravity support values against the baseline.

It is designed to calculate combined inertia of common load shapes for rotary actuator sizing. The reported outputs are individual/combined inertia; center-of-gravity support values.
The calculator uses Mass elements (kg, radius m) — one per line. Only use values that represent the same operating condition or design case.
The calculation follows: Standard rigid-body inertia + parallel-axis theorem. The page also states the assumptions that define where the method is valid.

Yes. PneumaForge converts supported units through canonical engineering units. For compressed-air reference flows and pressure bases, the reference pressure and temperature must also remain consistent.
