Locking Operation

Locked State(Swing Stroke＋Vertical Stroke 2mm)

(Boosting Stroke 4mm)

① The piston rod rotates while
it descends along the cam.
② After swing completion,
the piston rod descends vertically
until the lever clamps the workpiece.

No Hydraulic Use

The piston rod descends andthe boosting piston activates.
Exerts strong clamping force
and holding force with the wedge
mechanism.

Holding Force

Washing fixture system with high-power pneumatic clamps exerting
equivalent force to hydraulic clamps needs no hydraulic pressure.

Powerful
Clamping Force

Minimal clamping force and powerful holding force minimize workpiece
deformation. Mechanical locking allows holding force to exert 3 times
the clamping force at most.

Notes：※1. F ： Clamping Force (kN), Fk：Holding Force (kN), P ： Supply Air Pressure (MPa),F

L ：Distance between the piston center and the clamping point (mm).
※2. The specification value of cylinder force, clamping force, holding force and swing completion position repeatability is fulfilled
only when clamping within the lock stroke range.
(Please refer to "The specification value is not fulfilled when clamping out of the lock stroke range." on P.25.）※3. Minimum pressure to operate the clamp without load.
The clamp may stop in the middle of swing action depending on the lever shape. (Refer to "Notes on Lever Design" on P.25.)

Notes：※1. F : Clamping Force (kN), P : Supply Air Pressure (MPa), L : Lever Length (mm).
1. Tables and graphs shown are the relationship between the clamping force (kN) and supply air pressure (MPa).
2. Cylinder force (When L=0) cannot be calculated from the calculation formula of clamping force.
3. Clamping force shown in the below tables and graphs is the value when clamping within the lock stroke range.
(Please refer to "The specification value is not fulfilled when clamping out of the lock stroke range." on P.25.)
4. The clamping force is shown with lever in the locked position.
5. The clamping force varies as per the lever length. Please use it with supply pneumatic pressure suitable for lever length.
6. Operation in the non-usable range can damage the clamp and lead to fluid leakage.

Notes：※2. Holding force shows the force which can counter to reaction force in the clamping state, and differ from clamping force.
Moreover, keep in mind that it may produce displacement depending on lever rigidity even if it is the reaction force below holding force.
(When slight displacement is also not allowed, please keep the reaction force beyond clamping force from being added.)※3. Fk : Holding Force (kN) , P : Supply Air Pressure (MPa) , L : Lever Length (mm).
When holding force calculated value exceeds the value of a limit line, holding force is a value of a limit line.
1. This table and the graph show the relation between holding force (kN) and lever length (mm).
2. Holding force shown in the below tables and graphs is the value when clamping within the lock stroke range.
(Please refer to "The specification value is not fulfilled when clamping out of the lock stroke range." on P.25.)
3. Holding force indicates the value when the lever locks a workpiece in horizontal position.
4. Holding force varies depending on the lever length. Set the supply air pressure suitable to the lever length.
5. Using in the non-usable range may damage the clamp and lead to fluid leakage.

The graph shows allowable swing time against lever inertia moment.
Please make sure that an operation time is more than the operation(Total Operation Time)(Vertical Stroke)time shown in the graph.
Excessive action speed can reduce stopping accuracy anddamage internal parts.

Notes：※1. For any lever inertia moment, minimum 90°swing time should be 0.2 sec.
1. There may be no lever swing action with large inertia depending on supply
air pressure, flow and lever mounting position.
2. For speed adjustment of clamp lever, please use meter-out flow control valve.
In case of meter-in control, the clamp lever may be accelerated by its own
weight during swinging motion (clamp mounted horizontally) or the piston
rod may be moving too fast. (Please refer to P.25 for speed adjustment.)
3. Please contact us if operational conditions differ from those shown on
the graphs.

Cautions

Cautions● Notes for Design1）Check Speciﬁcations7）Notes for Lever Design● Please use each product according to the speciﬁcations.

● Please design the lever as light as possible, and it should be
no larger than necessary.

2）Notes for Circuit Design

The clamp may not function depending on supplying air pressure,● Ensure there is no possibility of supplying air pressure to the lockmounting position and shape of the lever. If using a large lever withand release ports simultaneously. Improper circuit design may leadthe mounting position shown below, it may stop in the middle of

swing action. Please use a lever with (Lever Weight W) × (Gravity
Center S) lighter than shown in the below list.

3）Swing lever should be designed so that the inertia moment is small.
● Large inertia moment will degrade the lever's stopping accuracySand cause undue wear to the clamp.
Additionally, the clamp may not function, depending on supplied
air pressure and lever mounting position.
● Please set the operating time after the inertia moment is calculated.

Lever

Please make sure that the clamps work within allowable operatingWtime referring to the allowable operating time graph.
● If supplying a large amount of air right after installation, action

4）When clamping on a sloped surface of a workpiece● Make sure the clamping surface and mounting surface of the clamp
are parallel.

8）The speciﬁcation value is not fulﬁlled when clamping out of thelock stroke range.
● The mechanical lock function will not work when clamping within
the range of swing stroke and idle stroke, and the speciﬁcation valueof cylinder force, clamping force, holding force and swing completion

Adjust the speed following "Allowable Swing Time Graph".
● Install a speed control valve (meter-out) and gradually control
the ﬂow rate from the low-speed side (small ﬂow) to the designatedspeed. Controlling from the high-speed side (large ﬂow) causes
