While it varies depending on usage conditions and calculation standards, generally speaking, Linipower Jack jacks operate with approximately one-third the power of hydraulic jacks.
This is because, while a linear power jack's motor only operates (consumes power) when the screw shaft extends or retracts, Linipower Jack system requires continuous oil supply to maintain the load even when the screw shaft is not extending or retracting.
In other words, because the hydraulic pump is running continuously, the power consumption increases.
Furthermore, since Linipower Jack Jack saves energy and significantly reduces carbon dioxide emissions, it can be considered an environmentally friendly product.

With the exception of some motor-equipped products, we are able to comply with the European RoHS Directive. Please contact us for more information.

In the standard specifications, if the shaft end is fixed or there is a mechanism to receive rotational force, the screw shaft will rise and fall without rotating, but if the screw shaft rotates, it will not rise and fall, so it is necessary to prevent the screw shaft of the jack from rotating.
There are two ways to stop the rotation: drilling a key groove into the screw and using a key to stop the rotation, or attaching a nut to the end of the screw and using the screw cover and nut to stop the rotation.

With the standard and anti-rotation specifications, the screw shaft rises and falls by rotating the nut, but with the traveling nut specification, the nut rises and falls by rotating the screw shaft.
No space is required for the screw shaft to move up and down, which saves space in the direction of movement.

Linipower Jack can be used when the jack surface temperature is between -15°C and 80°C during operation.

Outdoor protection measures such as painting and sealing are possible, but if the product is in an environment where it will be exposed to direct water, please take measures such as providing a cover yourself.

When a normal motor is used to stop by pressing, an impact occurs during pressing, which can cause a malfunction.
However, if you use a servo motor or similar to manage torque and operate the jack with a force below its basic capacity, it is possible to stop it by pushing.

Yes, it can be used. However, please be careful when using it as the allowable buckling load and allowable input rotation speed are limited.
Please check the technical data in the catalog "Power Cylinder / Linipower Jack" for details.

No. In case of linked operation, be sure to provide a guide.
By providing a guide, rotational force is prevented from being generated in the jack itself.

It can be used horizontally.
However, care must be taken when using a long stroke or with bellows, so please contact us if you have any requests.

Since multiple Linipower Jack will be used, please be careful to level the jacks, such as by adjusting the center height and input shaft height of multiple jacks.
Also, even when operating in a linked manner, be sure to provide a guide to prevent lateral loads.

By using an I-shaped bracket at the tip and attaching it with a clevis bracket or trunnion bracket (optional), oscillating operation is possible.

The clevis support on both ends is the optimum installation for oscillating operation. Please use it for oscillating operation.

We can make suggestions after thoroughly checking your usage environment.
Please let us know the ambient temperature, load conditions, operating speed, operating frequency, etc.
* Percentage duty cycle is the percentage of operation time per 30 minutes, based on a 30-minute period.
In this case, it means that there will be more than 9 minutes of driving time in 30 minutes.

We can provide special-shaped products. We have a proven track record, so please contact us for more information.

The backlash of the screw itself and the backlash of the worm gear become backlash on the input shaft.
This varies depending on the model and size, so please contact us.

For JWM (Trapezoidal Screw type), JWB (Ball screw type), and JWH (High lead ball screw type), it is possible to manufacture them with optional motors or Gear Motor.
Depending on the model number and motor capacity, products will be available as standard items, items with short delivery, or made-to-order items.
For details, please refer to the catalog "Power Cylinder / Linipower Jack".

A manual handle is available as an option. It can be used with a self-locking Trapezoidal Screw type.

Servo motors are suitable for applications requiring high-speed and high-frequency movement.
The jack limits the input rotational speed, so please pay close attention to the servo motor's rotational speed.
For high-frequency operation, please select either the JWB (Ball screw type) or JWH (High lead ball screw type).

It can be manufactured as a special-shaped product.
If you require oil lubrication specifications, please contact us.

For frame numbers 025 and above, we have established guidelines for lubrication cycles based on the frequency of daily use.
For frequent use, we recommend refueling once every three months.
Additionally, for JWB (Ball screw type) and JWH (High lead ball screw type) bearings, lubricate the upper bearing every six months.

Remove the hexagon socket plug and add grease until the grease poured into the grease nipple overflows from the hole in the removed hexagon socket plug.
After adding grease, re-wrap the sealing tape around the hexagon socket plug and tighten it securely to prevent grease leakage.

While the JWM (Trapezoidal Screw type) theoretically has a self-locking mechanism, the self-locking mechanism may not function due to vibration, shock, etc.
In such cases, a braking system is required.

In the standard specifications, the JWB (Ball screw type) and JWH (High lead ball screw type) have stoppers on the screws, so they will not fall out. However, the JWM (Trapezoidal Screw type) may have screws that fall out.
In that case, mechanical and electrical control will be necessary to ensure that it is used within the stroke limit.
*The stopper is designed to prevent the screw from coming loose, but if a greater force is applied, the screw may still come out.

The screw lead is larger than that of a standard JWB (Ball screw type), making it suitable for high-speed operation.
At the same speed, compared to a standard JWB, the input rotational speed of the drive source and reduction gear can be lowered, which is also effective in reducing noise from the jack.

While the JWB (Ball screw type) cannot withstand lateral loads, the JWM (Trapezoidal Screw type) can withstand a certain degree of lateral load, but only when stationary.
For details, please refer to the catalog "Power Cylinder / Linipower Jack".

The JWH (High lead ball screw type) is designed for high-speed operation, and therefore requires an air vent to quickly release air from inside the bellows, making it a special specification.

The traveling nut specification is designed so that the nut moves on the screw shaft, so the length of the bellows is determined by the stroke of movement, and the diameter of the bellows is determined by the installation direction of the nut.
Therefore, the selection of the bellows must be made on a case-by-case basis, and the method of attaching the bellows to the equipment also differs.

The table-shaped End fitting is coated with adhesive to prevent loosening of the screws and screwed onto the end of the screw shaft.
It is secured in place with set screws in two places to prevent it from loosening.
If you try to remove it forcibly, you may damage the end of the screw shaft. If you remove it, please return it to us.
If you intend to remove it yourself, please contact us.

We can also manufacture products with a spigot. The spigot is a convex part with tolerances, which is suitable for improving reproducibility and installation accuracy when disassembly and assembly of equipment is required. We can also accommodate customer requests for spigot diameter and dimensional tolerances, so please contact us.
For positioning, we can manufacture not only inlays but also those with positioning pin holes, so please contact us for detailed specifications.
