2. Transportation
1. Jacks that range under the standard capacity of 49.0kN (5tf) are provided with screw covers made of
hard vinyl chloride pipe. Never suspend or carry a jack by its cover.
2. If the Jack has a hanger, use the hanger to lift it. Before lifting, check the packaging, outline drawing or
catalog to confirm the weight of the jack. After the jack has been installed, avoid using the hanger to lift
it and the equipment that is connected to. This may damage the bolts, causing injury or equipment
damage if the equipment drops or the jack turns over.
3. The packaged product has uneven distribution of weight in the longitudinal direction. Be careful when
you carry the product.
3. Installation
1. Location of installation and atmosphere
Location
Indoor (No rain/water exposure)
Atmosphere ※
Dust level should be that of a

Operating
Temperature Range
－15℃to 80℃
Relative Humidity
85% max.
※In case of special specification, please confirm the final drawing because use conditions such a use
environment or ambient temperature might be different.
2. Do not place any obstacles that might prevent ventilation around the Jack. They can hinder cooling
resulting in a fire caused by abnormal overheating.
3. Never step or hang on the Jack. This may result in injury.
4. A stopper is not provided on the screw shaft of JWM. If the stroke capacity is exceeded, the shaft may
disengage from the unit or fail to function.
Screw shafts of JWB (Ball Screw Type) and JWH (High Lead Ball Screw Type) rotate and drop by its
own weight. The same is true for the traveling nut of JWB and JWH Travel nut type. Provide
anti-rotation measure to prevent the screw shaft and traveling nut from rotating at the time of
installation.
5. For JWB (Ball Screw Type) and JWH, (High Lead Ball Screw Type), do not operate input shaft
manually while loaded. Load pressure will rotate the shaft.
6. 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.
7. When installing a motor and reducer unit in addition to the jack body, prepare a robust counter making
allowance for a safety factor to prevent alignment accuracy at installation from being reduced even if
the maximum load is applied. Make sure that the transmission shaft connected to the input shaft is
aligned accurately (Fig.1).
Fig. 1
8. Using a floating shaft may result in malfunction due to vibration depending on rotation speed,
therefore, sufficiently consider rigidity of the shaft and backlash of the coupling.
※Operating temperature range refers to the
surface temperature of the jack during operation.
To check, measure the surface temperature of the
input shaft unit or travel nut (if used). Be sure all
the rotating parts have completely stopped before
proceeding to
measure.
★

9. To install a screw shaft or cover to the base, avoid drilling large holes so as not to reduce the surface
area of contact between the jack and the base.
10. See table 1 for bolt sizes to fasten the jack. Strength class 8.8 or above bolts are usually used for
mounting. Use 10.9 or above when load applies directly to the mounting bolts as in Fig.2.
Table 1. Bolt Sizes
11. Attach shaft end by applying an adhesive agent to its set screw. it is possible for the shaft end to
become detached by the rotational torque applied to the shaft. To avoid this, use one of the following
adhesives:
Provide a locking mechanism to the shaft end when an end fitting is attached . The screw shaft
receives a rotational torque and cause the end fitting to drop. Follow the instructions below to avoid
drop of the end fitting.
1) Apply an adhesive agent. Use the following brands or their equivalent. Read instructions and
safety precautions provided with each product before applying.
2) After tightening the end fitting, fix with the attached set screw (cone point or cut point) as a
locking device. For set screw sizes, refer to the end fitting configuration (dimensional drawing).
3) In atmospheres with a lot of vibration or temperatures higher than the operating temperature
range use dowel pins instead of set screws.
12. The jack’s thrusting force may cause the screw shaft (nut in the case of travel nut type) to rotate, in
which case a rotation prevention is required. When operating with the shaft end unconnected or
pulling the rope, use the rotation prevention type.
13. Do not use mechanical stops. This will cause major internal damage.
14. Apply load in the same direction as that of the screw shaft.
Load from inappropriate angles can bend the shaft (Fig.3).
For side load, make sure to use guides so the load or bending
momentum do not apply directly to the jack.
15. Be certain that the jack rating exceed the maximum possible stroke.
If the stroke capacity is exceeded, the shaft may disengage from the
unit or fail to function.
16. Consider maximum possible inertia before setting the limit switch.
This means calculating the maximum coasting distance affected

by specific load and installation conditions. Also, install a mechanical
stopper within the stroke range in case of emergency.
4. Operation
1. Be sure that the dynamic or static load carried or sustained by jack does not exceed its capacity.
2. Make sure that the surface temperature of the housing does not exceed temperature of -15ºC to 80ºC
during operation. If using a traveling nut type unit, measure the traveling nut surface temperature.
3. The maximum input speed is 1800 rpm as long as the input power dose not exceed the unit’s maximum
allowable input power.
4. Do not operate continuously. Maximum allowable input power ratings are based on a 20% duty cycle per
30 minutes for the JWM (Machine Screw Type) and 30% for the JWB (Ball Screw Type) and JWH (High
Lead Ball Screw Type). Duty cycle (%) per 30 min. can be calculated using the following formula: (30min.
- off time per cycle) / 30 X 100. For operation longer than that mentioned above or for any continuous
operation, the jacks temperature must be monitored and should not exceed 80ºC max. in order to
determine its duty cycle.
5. Be sure that starting torque is 200% or more of required running torque.
6. Be sure that ample driving power is available to drive the jack when using in temperatures below 0ºC.
Low temperatures decrease the jack’s efficiency due to the increased grease viscosity inside the gear
box.
7. Although JWM has self-locking feature, vibration and shock may affect its efficiency, in which case a
brake unit is required. JWB and JWH must have brake units that over power their holding torque because
of their extremely high efficiencies.
8. Never approach or touch the rotary parts (input shaft, etc.) or the screw during operation.
5. Maintenance and inspection
1. The jack is shipped prepacked with grease. Recommended grease brands are shown in Table 3. Under
normal operation, lubrication is required every 6 months, however, this interval may vary as frequency of
use and conditions change. Severe operating conditions will require a self-lubricating system. See Table
4 for the lubrication cycle.
※In case of the made-to order type, confirm with the final drawing, used grease might not be same as
standard.
2. When lubricating the screw, use a brush to spread the grease on the screw after the old grease has been
removed. See Table 5 for the amount of grease to be applied.

3 Reducer units JWM025/JWB025/JWH025 and above are provided with grease nipples and hex socket
plugs. Remove the plugs and pour grease through the nipples until it seeps from the openings. Then
firmly seal the openings with tape.
4Grease upper bearings for JWB (Ball Screw Type) and JWH (High Lead Ball Screw Type) using the
grease nipple set attached to their housings, at 6-month intervals.
Not necessary for jacks JWB010/JWH010 and below.
※In case of the made-to order type, confirm with the final drawing, grease nipple might not be same
as above.
4 Inspect regularly for general backlash and screw unit condition.
Jack life and replacement timing are determined by the following:
• JWM --- Backlash in the direction of screw shaft and nut
hits 1/4 of the screw pitch.
• JWB/JWH --- Visible particles due to wear and tear of the screw unit
• ALL types --- Check for backlash between the worm and worm gear.
Backlash excess of 30˚for H speed and 60˚for L speed
indicates the need to replace the worm and worm gear.
(Angle C in Fig.6)
Generally, continuous use without lubrication at recommended
intervals may cause inefficiency of shaft and failure of travel nut.

8. Options
(1)Counter LS Unit
The Tsubaki counter LS unit for LINIPOWER JACK works like the eyes and ears of the jack. It is a small-sized
stroke adjustment and detection unit that contains a feed cam mechanism and microswitches. The counter LS
unit has two internal microswitches. The unit runs the jack stroke through the gear mechanism, where the
strikers and microswitches detect and adjust the stroke. The display number of the counter LS unit changes by
one with each rotation of the input shaft.
■General Precautions
1. Newly delivered counter LS units have already been tested, but have not been adjusted for stroke.
Therefore, you must carry out stroke adjustment after the unit is installed. Be sure to take into
consideration the inertia of the jack when performing the stroke adjustment. If the travel screw is turned
while the input shaft fixed after adjustment, the adjusted settings will change. Therefore, do not allow the
travel screw to be turned (for traveling nut-types, do not allow the nut to be turned).
2. The counter LS unit contains precision parts and should not be subjected to severe shock or vibration.
■Connection
1. Note: As the wiring length increases, the signal power decreases.
2. Properly ground the main unit and the shielded wiring for the signal wires.
3. Always have the signal conductor and power wires away from each other. A noise filter should be installed
on any nearby devices that generate a lot of noise, signal wires should be shielded. Other necessary
countermeasures to prevent adverse effects should be performed.
4. Use a cable of the same gauge (dia.) as the connector of the counter LS unit. Using a cable that is too
thin or inserting discreet wires will render the waterproof feature of the unit ineffective.
5. If wiring is performed in an area where the counter LS unit may get wet from rain or other sources, make
sure that no water gets inside the unit causing it to malfunction.
■Setting the counter LS unit
1. Temporarily set (at "0" reset) the forward and reverse counter LS units for a short stroke near the stroke
center of the jack. Make sure that the units can move properly.
2. Set the jack at the position where you want it to stop by manual operation, or by inching (the forward limit).
(Check to see which direction the numbers on the display of the counter LS unit are moving. Refer to Figs.
4 through 7.).
3. Push the reset button of the counter LS unit. The display number changes to "00000" and the striker sets.
When the display numbers of the counter LS unit are changing from "00000" to "99999", or vice versa, the
striker activates a microswitch.
4. Do the same for the reverse direction (i.e., after setting the limit for the forward direction, set the limit for
the reverse direction). (Be sure not to allow the screw axis to rotate changing the settings that have been
made. For traveling nut-types, do not allow the nut to rotate)
5. The terminal block sets the contacts for each microswitch. Therefore, take into account the forward limit
and reverse limit when wiring.

(2) Position detection unit (option)
Three types of position detection units can be built in at most.
Micro switch: 4 pieces.
Potentiometer: 1 pc.
Rotary encoder: 1 pc.
Structure
Following shows the unit diagram consisting of micro switch, potentiometer and rotary encoder.
∎Note
1. Newly delivered micro switches have already been tested, but have not been adjusted for stroke.
Therefore, you must carry out stroke adjustment after the unit is installed. Be sure to take into
consideration the inertia of the jack when performing the stroke adjustment. If the travel screw is
turned while the input shaft fixed after adjustment, the adjusted settings will change. Therefore, do
not allow the travel screw to be turned (for traveling nut-types, do not allow the nut to be turned).
2. Position detection unit consists of precision parts. Never apply shock or vibration.
3. Never rotate LS cam strongly after fixing it by the set of screws. Otherwise, built in reducer can
brake.
∎Connection
1. Use the terminal block in the unit for the connection to each detector. Connection of each detector
to terminal block is previously completed.
2. In case of long distance wiring, signal loss can get worse.
3. Make sure to ground the shield wire of the detector unit and signal.
4. Locate the signal and power line separately. Put noise filter, shield the signal line, in case there is
a source of noise. Use shield wire for wiring rotary encoder.
5. Use suitable diameter of cable, which corresponds to the connector of position detection unit. In
case of smaller diameter cable or bulk cable, waterproof is poor.
Applicable cable diameter: SCL14B (12.5 to 14.5 mm dia.)
6. In case of wiring in rain or other wet environment, avoid water from entering the position detection
unit. It will damage the product.

(3) Specification of each position detector
∎Micro switch (Option code: K2 or K4)
※In case of the special specification, confirm the final drawing because model number, specification or the
number might be different.
Setting the internal LS (Option code: K2 or K4)
The position detection unit may contain either two or four microswitches for the internal LSs. The jack
stroke runs the output from the rotation of the input axis through the reducer, and changes the cam
rotation angle. When the cam reaches a specified position, it will activate the microswitch and stop the
jack. Then adjustment of the cam positions should be carried out.
1. Ensure that all connections have been properly made when adjusting the stroke.
2. At approximately the center of the stroke, ensure that (1) the cam is stopped by the operation of the
forward limit microswitch by screw extension and nut progression, and that (2) the cam is stopped
by the reverse limit microswitch by screw contraction and nut reversal.
3. Be aware that the momentum of the jack will prevent it from stopping immediately when the
microswitch is activated and that there will be a slight amount of overrunning. Take this into
consideration and adjust the microswitch activation position to point slightly in front of where you
actually want the jack to stop.
4. The rotary cam is affixed by two hexagonal bolts to the
shaft directly connected to the reducer. Turn and adjust
the cam after loosening these two bolts. Trying to turn the
cam without loosening these bolts may damage the
internal reduction gears. (Note: Use a hexagonal wrench
[2size] for loosening the bolts).
5. Adjust the cams beginning with the one farthest away (if
you start with the nearest cams you may not be able to
move the farthest ones). After adjustment, be sure to
tighten the bolts.

∎Potentiometer (Option code: P)
1. Potentiometer is set at half of the resistance
(500 ohm) at the middle of the stroke, unless
otherwise specified.
2. Never rotate the screw or nut during
transportation or installation, otherwise the
relation between the stroke and resistance
can get out of control. When the resistance
is incorrect, reset 500 ohm at the middle of
stroke.
Potentiometer output the stroke of the Linipower
Jack as the change of the value of resistance.
※In case of the special specification, confirm
the final drawing because model number or
specification might be different.
■Rotary encoder (Option code: R)
※Use with an equipment like sequencer or program controller, which controls the stroke as a digital signal.
1. Standard type has built-in incremental type encoder
2. It is possible to set an accurate home position of the machine in combination with a limit switch because
home position output is read out every 600 pulses.
3. Because the output is open collector type, output signal can be obtained when connected to a pull up
resistor.
Output voltage for signal 1 and 2: “H” is “(supply voltage - 1)V or more”
“L” is “1V or less”.
Reference for pull up resistance: DC 5V: 220Ω / DC12V: 470Ω/ DC24V:1kΩ
4. Rotary encoder is a precision instrument. Never apply vibration or shock.
5. Use shield wire for wiring of rotary encoder.
