Product Info Linear actuator
Tsubaki's Linear Actuator includes electric cylinders and jacks that use high-quality in-house screws, and our original Zip Chain-driven Zip Chain Actuators.
Both the screw mechanism and the Zip Chain mechanism can be used in a wide range of applications such as high-speed and high-frequency operation and operation that requires high accuracy by making the best use of the features of the product.
※Zip Chain mechanism is our original technology in which two chains interlock like a zipper to form a single, strong column that can be used by 'pushing and pulling'.

Zip chain mechanism
- High speed
- high-frequency
- High durability
- Compact
This mechanism uses Tsubaki original “Zip Chain” technology.
It is excellent in compactness and has the features of high speed, high frequency, and durability required for high-tact operation.
Two chains are interlocked to form a single column, enabling push-pull operation.
It is named Zip Chain as it engages like a zipper.

Ball screw mechanism, trapezoidal screw mechanism
- high-frequency
- Large allowable load
- Low noise
Ball screw mechanism
This mechanism is designed to operate at high efficiency by placing a steel ball between the screw shaft and nut to create rolling friction.
Compared to trapezoidal screw mechanisms, it is suitable for high-speed and high-frequency applications, making it suitable for assembly lines and other applications where productivity is required.
In addition, its high efficiency allows the drive source to be made compact.
The use of highly reliable internally manufactured ball screws makes it possible to predict operating life.
A ball screw with a longer lead per revolution is called a high-lead ball screw, which can achieve higher speeds at the same input rotation speed as a normal ball screw.
Trapezoidal screw mechanism
This mechanism operates by sliding friction between the screw shaft and nut, and is suitable for low-speed, low-frequency operation such as maintenance applications.
It has self-locking features not found in ball screw mechanisms, enabling load retention.
It is also economical due to its simple structure.

Innovative drive unit for high-speed, high-frequency operation and low floor space
Linispeed Jack is an innovative ball screw units optimized for servo motor drive.
Normally, a lifting mechanism using ball screws requires the arrangement and assembly of related parts such as reducers and ball screws.
With Linispeed Jack, all of these components are unitized, greatly reducing the time and effort required for selection and installation.
We also have a large number of experience in replacing hydraulic and pneumatic cylinders.
Linispeed Jack
Model No. SJ~
Ball screw lifting unit that maximizes the performance of servo motors
- ・Reduction of man-hours for selection and installation :
The ball screw and reduction gear are compactly integrated into a unit, which reduces the number of components and saves time and effort in selection and design. The optional servo motor flange eliminates the need for a servo motor coupling. In addition, the small number of components means that few adjustments are required, and installation is easy. - ・Ultra-high Speed :
Linispeed Jacks provide a rated thrust that can convey large loads in 200mm/s high-speed operations with no increase in size. - ・Continuous operation :
High frequency operation of up to 100% ED is possible.
(*%ED: Percentage of operating time within a given operating cycle. Therefore, 100%ED=continuous operation possible) - ・Low-floor / Compactness :
Low floor is achieved by incorporating the ball nut into the gear case. - ・Longevity :
The high-performance ball screw achieves a much longer running life than before.
