Although it depends on the usage conditions and calculation criteria, the Lini Power Jacks operate using about one-third of the power when compared with typical hydraulic type jacks.
This is because the Lini Power Jack operates the motor (consumes power) only when the screw shaft extends or retracts, while a hydraulic jack needs to feed oil continuously to keep the load even when the screw shaft does not extend or retract.
Such continuous operation of a hydraulic pump leads to much power consumption.
Moreover, the Lini Power Jack allows significant reduction of carbon dioxide emission as well as energy savings. It can be called an environmentally friendly product.

With some exceptions of jacks with a motor, we can provide products that conform to the RoHS Directive. Make an inquiry with us for details.

With a standard model, when the shaft end has been fastened or a rotation receiving mechanism is provided, the screw shaft does not rotate during lifting and lowering. If the screw shaft rotates, lifting and lowering is disabled, so that you need to prevent the rotation of the screw shaft of the jack.
Two methods are available: One is to machine a keyway in the screw to stop rotation with a key, and the other is to attach a nut at the end of the screw and stop rotation with the screw cover and the nut.

In the standard package and the rod rotation-prevention package, the screw shaft moves up and down by rotating the nut. On the other hand, the mechanism of the travel nut package works to move the nut up and down by rotating the screw shaft.
The travel nut type does not require lifting/lowering space for the screw shaft, which saves space in the direction of movement.

The Linipower jack can operate in a state in which the jack surface temperature is in the range of -15 to 80℃.  

We can provide some measures to adapt it for outdoor use, such as painting or sealing. In an environment where water splashes directly on the equipment, you need to furnish a cover or similar protection.

When a mechanical stop is applied to ordinary motor drives, the stop creates shock, which can result in product breakdown.
A mechanical stop can be used only when the jack is operating below its basic capacity while controlling the torque with servo motors, etc.

Yes, you can. Since, however, the allowable buckling load and allowable input rotation speed will be limited, pay due attention while using the equipment.
Refer to the technical data in the catalog "POWER CYLINDER LINIPOWER JACK" for details.

No, they don't need it. Note, however, that you must provide guides when using multiple jacks in conjunction.
The jack is designed not to generate a rotation force when a guide is provided.

Yes, the Linipower Jack can be used for horizontal applications.
However, certain considerations are needed for applications that involve bellows or long strokes, so in such cases, consult with us before use.

Multiple Lini Power Jacks are used in this application, so please take due care in leveling the jacks and ensuring their alignment, specifically for the jacks' core height and input shaft height.
You must install guides to tolerate side loads even for interlocked operation.

Linipower Jack can provide oscillation by using the I-shaped fitting for the end part and mounting it with a clevis mounting adapter or trunnion bracket (optional).  

Clevis mounting on both ends is the best installation to employ for oscillation operation. Use for oscillation operations.

We can propose a relevant product solution once we have a full understanding of the environment in which you are intending to use our products.
Please let us know your operating conditions, including ambient temperature, load conditions, operating speed, and frequency.
* Percentage duty cycle means the percentage of operating time per 30 minutes.
In this case, there is an operating time of 9 minutes or more in a 30 minute unit.

We can provide customized shafts as a special order. We have a wide variety of experience in delivering numerous customized products. Contact us for specific information.

The backlash at the input shaft is caused by the clearance of screws and worm gears.
Thus, it depends on the model and size. Contact us for specific information.

Models with a motor or geared motor are optionally available for the JWM (trapezoidal screw type), JWB (ball screw type), and JWH (high lead ball screw type).
There are standard products, quick delivery products, and made-to-order products depending on the model number and motor capacity.
Refer to the catalog "POWER CYLINDER LINIPOWER JACK" for details.

A manual handle is offered as an option. It can be used with a trapezoidal screw type that has a self-locking function.

A servomotor is suitable for the applications which require high speed/high frequency operation.
There is a limit on the input rotation speed of the jack. Be extremely careful about the rotation speed of the servomotor.
For high frequency operation, select the JWB (ball screw type) or JWH (high lead ball screw type).

We can provide this as a special order.
When ordering the oil lubrication type, contact us for specific information.

For frame sizes 025 and over, standard greasing intervals are set as follows according to the frequency of daily use.
In the case of high-frequency operation, it is recommended that grease is added once in three months.
For JWB models (ball screw type) and JWH models (high lead ball screw type), the upper bearing should also be greased every six months.

Remove the hexagonal socket plug and pour in grease from the grease nipple until the grease overflows from the hexagon socket plug hole.
After supplying grease, wrap the seal tape around the hexagonal socket plug and tighten it so that there is no grease leakage.

The JWM model trapezoidal screw type) has self-locking properties in theory, but it may not work when there is vibration or shock.
In such cases, a brake system is required.

With the standard specifications of the JWB (ball screw type) and JWH (high lead ball screw type), the screw is equipped with a stopper so that it does not fall off. With the JWM (trapezoidal screw type), however, the screw may possibly fall off.
In such a case, some mechanical/electrical control is required to ensure that the jack will be used within the stroke range.
* Note that the stopper is a simple preventive measure. The screw may fall off if any larger force is applied.

The screw lead is larger than the normal JWB models (ball screw type) and is suitable for high-speed operation.
When used at the same speed, the JWH operates at lower input rotation speed of the driving source/reducer than that of the JWB, which is effective for reducing the noise from the jack.

The JWB (ball screw type) cannot accept side load. The JWM (trapezoidal screw type) can withstand side load to a certain degree as long as it is stationary.
Refer to the catalog "POWER CYLINDER LINIPOWER JACK" for details.

The JWH model (high lead ball screw type) is intended for high-speed operation. An air hole is provided to quickly release the air from the bellows, which makes the model a special package.

The Travel Nut Package features a structure in which the nut moves along the screw shaft. The travel stroke determines the length of the bellows, and the nut mounting direction determines the bellows' diameter.
For this reason, the bellows is selected accordingly. Similarly, how the bellows is mounted on the equipment can vary.

The table-shaped end fitting is fixed until screw end with glue.
It is fixed with two screws to prevent untighten.
It might be broken the product if you remove the table-shaped end fitting forcebly.Please return products to us if necessery.
Please ask us when you would like to disassemble the fitting.

Inlet can also be manufactured. The inlet is a convex dimensional section with tolerances, suitable for improving reproducibility and installation accuracy when equipment needs to be disassembled and reassembled. Inlet diameter and dimensional tolerances are available to meet customer requirements, please contact us.
For positioning, we can manufacture not only inlets, but also those with positioning pin holes.
