What is Zip Chain ?
- High-speed, high-frequency operations
- Multi-point stopping function
- Save overall space
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 has been developed as a linear actuator products using this chain.
Compared to conventional pneumatic / hydraulic cylinders, this has many features including environmental considerations such as space saving, high-speed / high-frequency operation, multi-point stop function, high stopping accuracy, and free mounting direction. Widely used from small actuators to large lifters.

Tsubaki Zip Master ZME Series
Features
Overwhelmingly higher-speed/frequency operation than other drive systems.
The Zip Master realizes superior high-speed/frequency operation over other drive systems by using Zip Chains, which can provide continuous operation.
- ・High speed ：Max. 1000mm/s
- ・high-frequency ：300 strokes / hour is also possible
- ・Longevity ：More than one million lifting strokes
A self-standing type that offers excellent rigidity even over long strokes.
The Zip Master uses a highly rigid column with a compact design. This structure allows it to withstand overhang load even over long strokes thanks to its built-in linear guide.
- ・High lifting ：2,000mm or more strokes are also available.
- ・High rigidity ：Adopts the same linear guide as the Lift Master.
Plug and play type reduces labor for assembly thanks to its easy installation.
The plug and play type has an integrated structure that includes Zip Chains, liner guides, and motors.
The Zip Master can be used immediately, unlike conventional lifting devices that require labor for design/assembly.
＊ Can also be used as a vertical conveyer.
Realized multi-point stopping/multi-level positioning.
Easily realizes multi-point stopping/multi-level positioning thanks to its simple control structure.
Structure and cpmparison with other lifting methods
■ Unique inside structure
Comparison with drop lifters
Conventional vertical transfer lifters require on-site equipment assembly as well as scaffolding on the top for installing and inspecting the drive section.
ZIP MASTER’s integrated structure simpli es assembly and installation. In addition, the drive section is located on the bottom, enabling safe and simple inspection and maintenance.

Cautions for ZIP MASTER Selection
- ・ZIP MASTER achieves high-speed operation, and inverter drives are essential. Please make sure to operate with sufficient acceleration and deceleration time.
Rapid acceleration and quick stop may affect stopping accuracy or cause workpiece vibration.
When ZIP MASTER shakes depending on the table or arm rigidity or the load condition, take a longer acceleration and deceleration time when starting or stopping the operation.
Consider fixing the upper end of ZIP MASTER to reduce workpiece vibration.
- ・The nominal speed of ZIP MASTER is the maximum speed.
Make sure to consider the acceleration/deceleration time when calculating lifting/lowering time.
- ・Using a servomotor drive is recommended when faster lifting time, higher-frequency operation, multi-point positioning, or synchronized operation are required.
Contact a Tsubaki representative for more information.
- ・Provide an inverter regenerative resistor with sufficient capacity according to the operating conditions to handle the large regenerative current generated during lowering.
Consult the inverter manufacturer for regenerative resistor capacity.
- ・Use of an inverter with a capacity larger than that of the motor is recommended.
- ・Set up a sequence for activating the brake in the event the inverter trips.
- ・ZIP MASTER is driven by an induction motor with brake.
When a servomotor is prepared by the customer, make sure to select a brake type with a keyway on theshaft.
Also prepare a fall prevention mechanism to protect against falls.
Fall prevention pins are available upon request.
