1. Classification of the rotary cylinder (rotary actuator)
Rotary cylinder: An apparatus that transforms the energy of pressurized air into rotational movement
1) Vane type
The vane type is operated by the air pressure that operates on the hydraulic area of the fixed
wall installed on the cylinder.
Single vane: 270 to 300 , Double vane; 70 to 120 , Triple vane; below 60
Structurally, it's difficult to shut air completely.
2) Rack & pinion type
When the center that is geared to the rack gear linked directly to the piston, torque is acquired.
The type is most efficient among rotary cylinders. It's easy to install cushions. Also, component
forces are generated at the pressure angle of the rack gear. Also, friction increases because
horizontal thrust on the backside of the gear or piston occurs, but efficiency of 80 to 90 could
be obtained.
3) Screw type
When the stroke is enlarged as the straight movement changes to the rotational movement with the
screw on the thrust axis in the middle, the rotational angle could be great, but the exterior should
become larger. The efficiency ratio is about 80%.
4) Crank type
The linear movement changes to rotational movement by the crank. The angle of movement is
limited to 110 structurally, and the rotational force changes according to the angle of movement.
5) Wheel gear & chain type (hydro type)
The chain linked to the cylinder piston arranged in parallel is geared to the wheel gear.
With built-in oil on the part linked to the wheel gear, the type is used in processes that
require quiet rotation. Greater than 90% efficiency is possible.

2. Process of selecting rotary cylinder
1) Review of the size of the load
(1) Required torque when static power is required;
Ts = F x I (Nm) [ F:The force which is demanded(n), I:From load center distance until in rotary center (m) ]
(2) When the load changes
a) Calculation of the resistance torque
- When there is no change in load (horizontal use) K=2
- When there is change to the load (vertical use) K=5
b) Calculation of the acceleration torque
2 -2
(i) Acceleration torque Ta = 5 x I x ( /t ) x 10 / 10,000(Nm) [I : Inertial moment (Nm)]
: rotary actuator angle (rad), 90 = 1.5708(rad), 180 = 3.1416(rad), 270 = 4.7124(rad)
(ii) The inertial momentum is calculated according to the shape and weight of the load.
(iii) Each acceleration is calculated.
2
= /t(rad/s ) : rotary actuator angle (rad), t : rotary actuator time
c) Calculation of the required torque
Tt = TR + TL
In the angular rotational cylinder torque table, select the model that satisfies the equation .
2) Review of allowed energy
a) Calculation of the angular velocity
2
= /t(rad/s ) : rotary actuator angle (rad), t : rotary actuator time
b) Calculation of the inertial energy of the load
2 -1
E = 0.5 x I x x 10 (mj) / 10,000 [I : Inertial moment (Nm)]
When the inertial energy of the load exceeds the allowable energy of the rotary cylinder type,
a mechanism to absorb the impact is required.

is suitable
Finger attachable 90 swivel unit
Intake flange
Shock absorber
for connection to application specific
adapter plate adjustable end rotary
driving absorbency
Drive Kinetic
double acting pneumatic pinion/toothed rack system for low tolerance
cylinder Body transmission of drive power in one rotation
movement
high-tensile aluminum body with
lightest possible because of
hard anodizing
