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 actuator that achieves overwhelming space savings
Zip Chain is a chain developed exclusively by our company that consists of two chains that interlock like a zipper to form a strong rod, enabling pushing and pulling operations.
Zip Chain Actuator is a completely new linear actuator that uses this technology.
Zip Chain can be stored in a compact case, achieving overwhelming space savings compared to conventional linear actuator. It also supports high-speed, high-frequency operation, and uses significantly less power than hydraulic or pneumatic cylinders. Furthermore, it allows for highly accurate multi-point stopping, and can be installed in any direction.
Zip Chain Actuator
Model number ZCA~
Unprecedented high-speed, high-frequency, low-profile, long-life actuator
- ·compact:
The chain case is low, about 1/10 the height of the stroke, so it can be installed in a small space. It can be made even more compact by integrating it with the drive unit such as the gear motor. - ・High-speed driving:
Achieves high speed operation of up to 1000mm/s, surpassing the speed of screw-type, hydraulic, and pneumatic cylinders. - ・ Percentage duty cycle 100%ED:
Using a servo motor allows for highly accurate multi-point stopping and continuous operation. - ・Long life:
It has excellent wear resistance and does not stretch, so it has an expected travel distance of 4000km. - ・Free installation direction:
It can be freely installed in the direction that suits your needs, such as lifting, horizontally, or hanging. - ・A wide range of products:
All sizes are available with Hypoid Motor. The TERVO servo reducer is integrated with the servo motor, enabling high-speed positioning operation in a compact structure. - - We can also handle medium and large sizes with a maximum thrust of 38.2 kN and a maximum stroke of 5000 mm.
