Use the Pneumatic Rotary Actuator Torque Calculator to calculate torque from vane/rack-pinion effective area/lever geometry and pressure. The calculator uses Working pressure, Effective displacement per revolution and Efficiency and reports theoretical torque.
Read the result in the context of the selected units and pressure basis. For this tool, the primary outputs are theoretical torque. Change one input at a time when comparing scenarios so the effect of each variable remains clear.
PneumaForge applies this verified method: Pressure × effective displacement/lever relation appropriate to actuator model. The functional engine is shared with related tools in the rotary-torque family, while this page solves the specific intent represented by pneumatic rotary actuator torque calculator.
Pressure × effective displacement/lever relation appropriate to actuator modelReproducible example: start with the calculator's default values (Working pressure = 6; Effective displacement per revolution = 0.2; Efficiency = 80) and calculate the result. Then change the variable most relevant to your application and compare the new theoretical torque against the baseline.
V_d/effective geometry and efficiency come from user/manufacturer data; no universal vane/rack mechanism constant.
It is designed to calculate torque from vane/rack-pinion effective area/lever geometry and pressure. The reported outputs are theoretical torque.
The calculator uses Working pressure, Effective displacement per revolution and Efficiency. Only use values that represent the same operating condition or design case.
The calculation follows: Pressure × effective displacement/lever relation appropriate to actuator model. The page also states the assumptions that define where the method is valid.
V_d/effective geometry and efficiency come from user/manufacturer data; no universal vane/rack mechanism constant.
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.
