Thank you for purchasing TSUBAKI POWER CYLIN ER F-Series.
To make best use of it, proper installation, operation and maintenance is required. This
manual contains such information and should be carefully read in order to maintain the
performance of your Cylinder.
If you have any questions, consult the distributor you purchased the cylinder from or the
Tsubaki sales office nearest you. The cylinder’s type, test number, and drawing number
shown on the nameplate attached to the main body of the cylinder will be required when
contacting your distributor or our sales office.
 Initial Inspection
Be sure the package is right side up before unpacking and then check for the following:
1. Make sure that the “Type”, ”Rated Load”, “Speed”, “C12V or C24V” and
“Stroke” stated on the nameplate conforms to that of your order specifications. Also, confirm
that the accessories enclosed are the same as those you ordered.
2. Check to see that no damage occurred during delivery.
3. Check that the nuts and bolts on the unit have not loosened.
 Consult the distributor you purchased the product from if you encounter a problem.
 Installation
1. Atmosphere of location for installation
Installation Location Indoors or Outdoors with a waterproof
connector
Atmosphere ust level should be that of a normal factory.
Ambient Temperatures -15ºC to 40ºC
Shock Below 1G
Ambient Humidity 85% max. (no condensation)
2. The load direction applied to the cylinder must be on the same line as that of the rod;
otherwise the cylinder will incur inappropriate side force or bending moment that may
result in serious internal damage to the cylinder. If side force or bending moment can
not be avoided, use liner guide to account for it.
3. To connect the cylinder to a mating machine, use the pins of dia. 7.924 to
7.96 at the rod side and clevis side. To prevent wear of hole, use the pins having
smooth surface. It Is better to apply grease to the pins when connecting.

5
4. If the cylinder swings while operating, install the cylinder so that both coupling pins are
arranged parallel with each other at a right angle to the swinging plain. Check that the
front ends of clevis and rod does not interfere with the mount of mating machine.
Fig. 1
5. The mating machine should have ample strength as over 300% of rated thrust, if
overload protection unit by TC.
6. Never step or hang on the cylinder. This may result in injury.
7. The rotating torque at the rod will be occurred while operating, so anti rotating
connection is required at the mating machine. The value of rod rotating torque is as
follows.
LPF010H LPF020M LPF040L
Rod Rotating
Torque 0.14 (N･m) 0.28 (N･m) 0.55 (N･m)
8. When using equipment that must avoid all contact with oil or grease such as food
processing equipment, make sure a protective device such as an oil receiver is
attached to prevent damage from oil leakage resulting from equipment damage or
overuse. o not place any obstacles that might prevent ventilation around the cylinder.
They can hinder cooling resulting in a fire caused by abnormal overheating.
9. The cylinder should be used within the stroke on the drawing. To do that, to use limit
switch (LS) for stroke adjust on the equipment prepared by customer or to use the
optional limit switch by TC. Before adjusting the limit switch, must check each LS at
the end works well with proper direction of motor. When adjusting the limit switch,
should be set with counting additional stroke by inertia after power off.

 Wiring
1. For connection of power supply and cylinder, should follow government law and other
related rules for wiring in each country. In generally, use the wire leads, which have
width of over 2mm
2
and within 3m long. The specified performance of LP cannot be
obtained due to voltage drop. In the case of outdoor use or in the place where it may
be wetted, use the waterproof connector.
When connecting the black wire to “+” and red wire to “-“, the rod goes forward.
Reference Circuit iagram ( ynamic braking)
The above reference circuit diagram shows the condition of dynamic braking is working.
When cylinder forwards, turn the forward relay from “b” to “a”.
2. Power Supply: Use a power source with a sufficient capacity in consideration of the
locked rotor current (see the table above). If power supply is not sufficient, cylinder
malfunctions or operation speed is decreased.
Use the following capacity of the relay
C12V Model : 30A or greater (14V C)
C24V Model : 30A or greater (28V C)

 Optional Units
1. External Limit Switch for stroke adjustment (Option name : “L”)
General Caution, when using External Limit Switch
★ In the case of H speed, there is possibility that the striker runs over contact point
of LS. Therefore, electrical self-hold of LS contact is required at the customer’s
electrical circuit diagram.
★ Coasting: As the cylinder is driven by motor, so that the rod moves by Inertia of
motor even after the power is turn off. Inertia depends on the model and load.
Therefore the limit switch should be set on a little inside of designed stroke in
consideration of coasting. For your reference, below is shown the coasting
distance for each model in rated loaded state. When short coasting distance is
required, dynamic braking diagram is recommended.
2. Potentiometer (Option name : “P”)
Potentiometer is a variable resister to output electrical signals by stroke.
General Caution, when using Potentiometer
★ Resister is preset by model of Power Cylinder before delivery. o not rotate
the actuator rod before installation. It will result the stroke position will be out of
phase with potentiometer

General Caution, when using K2
★ The position of Limit Switch is not preset, when delivery. Before operating,
please set at customer side. o not rotate the actuator rod after set. It will
result the stroke position will be out of phase with K2.
How to set the K2
①. Check the wire connection is right
②. Move the cylinder rod to middle and check the limit switch work correct at both
directions with each cam and each limit switch.
③. The rod coast little after limit switch contact (= motor turn off). Therefore, the cam
should be adjusted with the coasting.
④. The cams are set on the output shaft of gear box with 2 of M4 set-screw. o not
turn the cam without loosen the set-screw. It will result the gear box will be broken.

 Cautions efore operating
1. Verify the wiring connection is correct, especially the relation between rod direction and
Limit Switch at each end. Then, power is turn on and verify the direction by inching
operation. This means to verify that the forward switch is turned on, then rod moves
forward and rod stops by the forward limit switch. o same thing for reverse side.
2. Verify the mechanical connection between the cylinder and equipment.
★ The rod should not be forced by any bending moment at any positions while full
stroke. If any bending force is occurred, the cylinder life will be shorten. Or
unusual sound or any damage will be happened.
 Frequency and ED% at operating
The frequency of starting and E % are limited cause of the temperature rise on motor.
And also, in the case of high frequency of operating, the expected cylinder life should be
considered.
Starting frequency : Two times per minute ( 1 round trip / min.)
Maximum E % : Less 25% (5 min. bases)
Expected life time : 15,000 cycle
* E % = (one operating time) / (one operating time + rest time)
In the case of inching operation, starting frequency should be less than 10 times per
minute.
 General cautions
1. The range of power voltage
The range of power voltage should be within 10-14V for 12v motor and within
20-28V for 12v motor. Otherwise, cylinder cannot be moved or motor temperature
rise. To verify the power voltage at nearest point to motor is very important, if
cylinder characteristic is different from usual.
2. The various loads
The kind of load in below effects the cylinder wrong. The performance of cylinder
is not good and or the cylinder life will be shortened.
★ Bending load to the rod
★ Impact load
★ Overload
★ Locked load
★ Press stopping (Use the option of “overload protection unit”)
