Product Info: Linear Actuator
Tsubaki's linear actuator include a lineup of electric cylinders and jacks that use high-quality screws manufactured in-house, as well as our proprietary Zip Chain Zip Chain Actuator.
Both the screw mechanism and Zip Chain mechanism make the most of the product's features and can be used for a wide range of applications, including high-speed, high-frequency operation and operation requiring high precision.
* Zip Chain mechanism is our proprietary technology in which two chains interlock like a zipper to form a single, strong pillar that can be used for both pushing and pulling.

Zip Chain Mechanism
- High speed
- High frequency
- High durability
- compact
This mechanism uses Tsubaki's proprietary technology, "Zip Chain."
It is highly compact and has the high speed, high frequency and durability required for high tact operation.
By interlocking two chains together to form one rod, it is possible to push and pull.
It was named Zip Chain because it interlocks like a zipper.

Ball screw mechanism/ Trapezoidal Screw mechanism
- High frequency
- Maximum allowable load
- Quietness
Ball screw mechanism
This mechanism uses steel balls placed between the screw shaft and nut to create rolling friction, allowing for highly efficient operation.
Compared to Trapezoidal Screw mechanisms, it is suitable for high-speed, high-frequency applications, making it suitable for assembly lines where productivity is required.
In addition, its high efficiency allows the drive source to be made smaller.
As we use highly reliable Ball screw manufactured in-house, it is possible to predict the running life.
Ball screw screw with a longer lead per rotation than a regular Ball screw is called a high-lead Ball screw, and can achieve higher speeds even with the same input rotation speed as a regular Ball screw.
Trapezoidal Screw mechanism
This mechanism works by the sliding friction between the screw shaft and nut, and is suitable for low-speed, low-frequency operation such as for maintenance purposes.
It has a self-locking property that Ball screw mechanisms do not have, making it possible to hold loads.
In addition, its simple structure makes it economical.

Linear Actuator Product List
An innovative drive unit that achieves high-speed, high-frequency operation and low profiles
Linispeed Jack is an innovative Ball screw unit optimized for servo motor drive.
Normally, lifting mechanisms using Ball screw require the separate procurement and assembly of related parts such as reducers and Ball screw.
With Linispeed Jack, all of these components are unitized, which greatly reduces the effort required for selection and installation.
We also have a proven track record of replacing hydraulic and pneumatic cylinders.

Ball screw lift unit that maximizes servo motor performance
- ・Reduction of selection and installation man-hours:
Ball screw and reduction unit are compactly unitized, which means fewer components and less time is required for selection and design. If the optional servo motor flange is used, a servo motor coupling is not required. Also, with fewer components, fewer areas require adjustment, making installation easier. - ・Super high speed:
A "constant thrust" has been achieved that allows heavy loads to be transported at high speeds of 200 mm/s without increasing the size. - ・High frequency operation:
High frequency operation of up to 100% ED is now possible.
(*%ED: Percentage of operating time within a certain operating cycle. Therefore, 100%ED = continuous operation possible) - ・Low profile and compact size:
A low profile has been achieved by incorporating the ball nut into the gear case. - ・Long life:
The high-performance Ball screw achieves a much longer running life than conventional products.
