Zip Chain Actuator

Zip chain was uniquely developed by Tsubaki.

Two chains lock together like a zipper to form a single, strong column for pushing and pulling applications.

Zip Chain Actuator
Useful Information
【Expanded line-up】 ZCA145 has been added to the Zip Chain Actuator line-up. (2016.10.03)
Some models (ZCA035 has been changed to ZCA135) have been improved. (2015.04.01)

1.Features

Compactness
Achieved 1/4 to 1/5 sizes compared to conventional linear actuators as this product can compactly house the Zip Chain.
Compactness
High-speed performance
Capable of higher-speed operation compared to screw type, hydraulic and pneumatic cylinders.
  • ZCA025, ZCA135: Maximum speed = 1000mm/sec
  • ZCA145: Maximum speed = 500mm/sec
Ecology
Uses less than 1/30th of the power of hydraulic and pneumatic cylinders. Combining dedicated sprockets, delivers high efficiency of nearly 90%.
Multi-point stopping
Multi-point stopping at any desired position is possible by controlling the input rotation.
Free mounting direction

Be sure to always attach a linear guide in the direction of travel. For hanging installations, you will need to check safety.

2.Construction

The interlocked chains form a single column to push and pull. Chains that are not engaged can be compactly housed in the plastic case, allowing for installation in tighter spaces.

  • 1. Bold: stock item
  • 2. Values represent basic capacities with an end fixture attached. Contact a Tsubaki representative regarding any other installation fixture requirements Values are obtained when operated at a maximum 0.35G (upper limit) acceleration. These values are applicable regardless of the type of installation (vartical, horizontal, hanging). However, be adviced that for ZCA025 unuts with input shafts on the opposite side, the basic capacity, allowable input shaft torque, and allowable overhang load will be smaller depending on conditions. See page 8 of the catalog .
  • 3. Use within the stroke range. Always install a linear guide in the direction of travel.
  • 4. Limited torque models. The motor output shaft torque exceeds the generated thrust. Contact us separately for other combinations of generated thrust and speed.
  • 5. ZCA135: Models with 1000mm stroke bellows are limited to a basic capacity of 431N{44.0kgf} or less.
  • 6. ZCA145: Models with 2000mm stroke bellows are limited to a basic capacity of 900N{91.8kgf} or less.

Note: See below regarding models with motors.

ZCA145: Not available with motors. Consider separately installing a motor.
