Tips: How to select a pneumatic rotary actuator
- Determine the following working conditions of a pneumatic rotary actuator according to the actual situation:
1.1 Rotation angle θ: The actual rotation angle must be within the maximum allowed range of rotation angle of cylinder.
1.2 Rotation time t: The rotation time must be within the maximum allowed range of rotation time of cylinder.
1.3 Installation position of cylinder: Allow enough installation space, so as to ensure leaving adequate space for rotation of cylinder and workpieces.
1.4 Determination of loading mass and loading shape. - Calculation of necessary torque needed when loading rotation (T(N.m))
Calculate the necessary moment required for loading rotation according to the formula below, and combine with the torque diagram of actual effect, to choose the pneumatic rotary actuator with suitable torque output.

2. compared with m, disregard if m is extremely tiny.
3. calculate K according to the shape of concentrated loading row by row. For example, when the loading is spheroid, K=2r²/5Note:
1. horizontal installation.
2. pay attention to the change of
movement time in case of vertical
installation. - Calculation of maximum movement energy E(max, J):
Calculate the maximum movement energy according to the formula below, and make sure that the maximum movement energy is within allowed energy range of the chosen pneumatic cylinder as excessively large movement energy would lead to damage of inner parts, please choose rotation cylinder attached with shock absorber when the movement energy is fairly large.
- Calculation of loading rate
Calculate the loading rate according to the formula below, and the loading rate must not be more than 1.
- Determination method
It could be used only when the chosen pneumatic rotary actuator must meet the requirements of article 2, 3 and 4 simultaneously.
