Case Study of the Downsizing of Dispensers (Filling Equipment)
Issue
Reducing Equipment Size
Conventional Equipment
A piece of equipment with a self-made mechanism that uses a stepper motor and ball screw to apply a constant and highly accurate amount of liquid.
- Application
- Dispensing of solutions, paints, adhesives, etc.
Conventional Problems
- There is limited installation space for the application nozzle, and the self-made mechanism can no longer be accommodated
Solution
Compact Electric Cylinder DR Series
Integrated Motor and Ball Screw for Space Saving
The use of the compact electric cylinder DR Series, which integrates a stepper motor and ball screw, allows the overall length of the equipment to be designed shorter than with a self-made mechanism.
Specific Application Examples
28 mm Frame Size Compact Body
Integrates a hollow rotor and ball screw nut, and features a structure that houses the ball screw in the motor section, making the product itself extremely compact.
- *The above structural drawing is an example.
Omits Space Allocated for Connecting Parts
Since connecting parts such as linear guides and couplings are no longer necessary, the equipment as a whole can be made smaller.

Can be Installed According to the Installation Space
The DR Series offers a wide variety of mounting methods. You can select a mounting method that maximizes the use of limited installation space.
When multiple units are used, they can be mounted closely together. It also contributes to space saving in terms of equipment width.

Eliminates Installation Space and Wiring for the Home Sensor
For αSTEP AZ Series Equipped Type*, position information is detected and managed by a mechanical absolute encoder, eliminating the need for a home sensor on the mechanism side. In addition to reducing the installation space for the sensor, sensor wiring can also be omitted.
- *The DR Series contains the αSTEP AZ Series-equipped type, and the PKP Series-equipped type. Please check the product page for details.
