wSpeed control is possible with meter-in and meter-out styles of speed
controllers. However, smooth acceleration and deceleration may not be
obtained by these speed controllers.
ML2B
eFor installation other than horizontal mounting, it is recommended to use
a system with reduced pressure supply circuit on the downward side.
(This system is also effective for a start delay at rise and air reduction.)
ML1C
Cushion adjustment
REC
REA
Cushion adjustment mechanism is not designed.
Cushion adjustment is not necessary because the model can perform
smooth acceleration and deceleration in a wide range of strokes without
an adjusting cushion.
RHC
MTS
Relieving port
CC
In general specifications, relieving port is blocked with a hexagon socket
set screw. This screw should not be removed, because dust may enter
inside through the relieving port. Hexagon socket set screw is not
prepared for clean room specifications, and use it as relieving port
accordingly.
Cycle time
Due to the nature of its construction, this cylinder starts and stops
gradually. Therefore, the length of time for the stroke could be longer
than that of ordinary cylinders.

Operation Principles
1. In-rush
4. Deceleration
Actuating air passes from cylinder head and enters the right chamber of the cylinder
from space between cushion seal and U-shaped groove on the outer surface of
cushion spear. Air in the left chamber of the cylinder passes through space between
cushion seal and piston rod, and is released to the cylinder port on rod side.
When cushion spear on rod side meets cushion packing, air in cushion chamber on
rod side flows through space between cushion spear groove and cushion seal. Since
the space is reduced as a SINE function, the cylinder rod decelerates smoothly.
2. In-rush / acceleration
5. Stop
Differential pressure (theoretical thrust) generated on the left and right sides of piston
becomes larger than starting resistance, and piston starts to actuate. With the
actuation, U-shaped groove on the cushion spear outer surface gradually becomes
deeper, air flow necessary for piston enters the right chamber of the cylinder, and
piston accelerates. This acceleration process can be achieved smoothly (as a SINE
function) by using a cushion spear on which a U-shaped groove is machined.
The piston stops at the stroke end on rod side with smooth cushioning. Air flow which
is switched by solenoid valve is reversed from the one indicated in the above "1 Inrush".
3. Acceleration
6. Reset
When piston starts to actuate, air can go in and out freely because cushion spear on
head side is released from cushion seal. With this actuation, piston speed accelerates
(or maintains the same speed).
Air enters left chamber of piston from cylinder port on rod side through space between
cushion packing and U-shaped groove on outer surface of cushion seal. Also, air in
right chamber of piston is exhausted from cylinder port. As U-shaped groove on the
cushion spear outer surface gradually becomes deeper, the cylinder accelerates.
