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.

Chain Meshing Type Actuators

Zip Chain is a chain uniquely developed by Tsubaki. Two chains interlock like a zipper to form a single, strong column for pushing and pulling applications.
Zip Chain Actuator is an entirely new linear actuator that employs this mechanism.

Zip chain can be stored in a compact case, saving a large amount of space compared to conventional linear actuators.
With support for high-speed, high-frequency operation, Zip Chain Actuators consume significantly less power than hydraulic/pneumatic cylinders. High-precision multi-point stopping is possible, and the mounting direction is also free.

The zip chain actuator has been developed as a linear actuator products using a zip chain.

  • ・Compact :
    The height of the chain case is about 1/10 lower than the stroke, and with its drive-integrated structure this compact unit can be installed in narrow spaces.
  • ・High-speed operation :
    Achieves a maximum speed of 1,000mm/sec during high speed operation, which far outstrips the speeds seen in screw type cylinders and hydraulic/pneumatic cylinders.
  • ・Hourly load rate 100% ED :
    Servo motors enable high precision multi-point stopping and continuous operation.
  • ・Longevity :
    Features superb wear resistance and less chain elongation, which gives it an expected travel distance of 4,000km.
  • ・Mounts in any direction :
    Can be freely installed in any direction to meet any customer need, such as lifting, horizontal movement, and hanging.
  • ・Rich lineup :
    All sizes are available with hypoid motor. The reducer TERVO integrated with a servomotor can achieve high-speed positioning operation in a compact configuration.
  • ・Medium and large sizes with a maximum thrust of 38.2 kN / maximum stroke of 5000 mm are also available.
