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'.

Tsubaki's linear motion takes full advantage of the features of the Zip chain mechanism and screw mechanism, and each product covers the optimum capacity range. Select the most suitable linear motion mechanism for your equipment.

Zip chain mechanism

It is excellent in compactness and has the features of high speed, high frequency, and durability required for high-tact operation.

What is the zip chain ?

Zip Chain is a chain uniquely developed by Tsubaki for pushing and pulling applications.

Two chains lock each other to form a single column, and is named as Zip Chain because it engages like a zipper.

Features

Ball screw

  • ・Ideal for high-speed, high-frequency applications such as assembly lines.
  • ・Highly efficient and compact drive source
  • ・Predictable operating life

Trapezoidal Screw

  • ・Ideal for low-speed, low-frequency operation such as maintenance applications
  • ・Economical with a simple structure
  • ・It has self-locking property and load retention is possible.

The LiniSpeed Jack is an innovative jack that provides high-speed, high-frequency operations and low-floor specifications. (Refer to the banner above for details.)

Linispeed Jack is an innovative jack optimized for servo motor drive that overturns the common sense of conventional jacks.
High-speed lifting of 200 mm/s and improvement of hourly allowable load ratio achieve maximum 100% ED. Furthermore, the ball nut is built into the gear case has realized a lower floor significantly and reduce the height of entire equipment.

High-performance ball screw has more than twice the service life of selected conventional jacks and can be used in applications such as robot lifting sections, transfer equipment and PCB cleaning equipment, where conventional jacks cannot be used.
In addition to standard type, travel nut type is also available in which does not require a pit installation, and the nut moves up and down by rotating the screw.

Realizes unprecedented high-speed and high-frequency operation that can make full use of servo motors.

  • ・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 :
    Provides high-frequency operation beyond what you believe jacks are capable of. :Linispeed Jacks achieve the maximum of 100% ED for allowable load hourly rate, and provide continuous operation.
  • ・Low-floor / Compactness :
    Even if the operating speed is increased, it can be accommodated in a smaller size than the conventional jack, and the newly developed structure with the ball nut built into the gear case has realized a lower floor.
  • ・Longevity :
    In addition to achieving ultra-high speed and high-frequency operation, we have achieved a much longer running life than before by using a high-performance ball screw.
  • ・User friendly :
    Linispeed Jacks have the same easy installation and ease of synchronized operation while enabling high-speed, high-frequency operations and lower height.
