Zip Chain Actuator

1．Features

Compactness

Achieved 1/4 to 1/5 sizes compared to conventional linear actuators as this product can compactly house the Zip Chain.

High-speed performance

Capable of higher-speed operation compared to screw type, hydraulic and pneumatic cylinders.

ZCA125, 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

Vertical installation

Horizontal installation

Hanging installation

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.

3．Reference Number System

ZCA	1	35	M	050	-	2G	*	*
(1)	(2)	(3)	(4)	(5)		(6)	(7)	(8)

(1) ZCA = Zip Chain Actuator
(2) Model no. : 1 = Frame number 25, 35, 45
(3) Frame number: 25, 35, 45
(4) Motor*: M = With motor (200V class), N = Without motor (Only N: No motor is available for ZCA145)
(5) Stroke:
(Frame number 25) 030 = 300mm, 050＝500mm
(Frame number 35) 050 = 500mm, 075 = 750mm, 100 = 1000mm
(Frame number 45) 100 = 1000mm, 150 = 1500mm, 200 = 2000mm
(6) Motor capacity and reduction ratio: Contact a Tsubaki representative for motor specifications. (Frame number 25 and 35 only.)
(7) Installation direction
(8) Option

400V class motors are made-to-order
Contact a Tsubaki representative for motor specifications.

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).
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. ZCA125: Models with 500mm stroke bellows are limited to a basic capacity of 300N{30.6kgf} or less.
6. ZCA135: Models with 1000mm stroke bellows are limited to a basic capacity of 431N{44.0kgf} or less.
7. ZCA145: Models with 2000mm stroke bellows are limited to a basic capacity of 900N{91.8kgf} or less.
Contact a Tsubaki representative for models with motors.
ZCA145: Not available with motors. Consider separately installing a motor.
