Miniature Servo Electric Cylinders
Define the complete cylinder, from mounting to fault response
Miniature servo electric cylinders combine a driven linear mechanism with a housing and output interface. For a machine builder, the useful selection boundary is the complete axis: mounting, stroke limits, feedback, drive compatibility, guidance and behavior when power is removed. A thrust figure alone leaves these integration questions open.
Request the applicable drawing / CAD revisionThis is a configuration review, not a stocked SKU listing. Ratings, documentation availability, sample scope and lead time are confirmed for the reviewed design.
The first design decision
Which parts of the axis must arrive integrated, and which remain in your machine design?
Define these boundaries
- A cylindrical housing does not establish an ingress-protection rating or suitability for washdown.
- Holding a vertical load after power loss requires an explicit mechanical and controls review. Self-locking must not be assumed.
Configuration choices and required evidence
Use this matrix to compare candidate configurations. Entries describe decisions to make and evidence to request; they are not unverified product ratings.
| Design input | Options to review | Evidence for the decision |
|---|---|---|
| Supply boundary | Mechanical cylinder, motorized axis or axis with drive | Responsibility matrix for motor, controller, sensors, cables and integration. |
| Output guidance | Rod with external guide or an integrated guided arrangement | Tool mass, side loads, moments and permitted rotation. |
| Travel and sensing | Mechanical limits, home switch and position feedback | Useful stroke, stop clearance, reference recovery and overtravel handling. |
| Power-off state | Permitted movement, holding device or externally supported load | Load direction, safe-state requirement and recovery sequence. |
Agree on prototype acceptance before sampling
- 01
Draw the machine interface
Locate mounting faces, output attachment and the moving tool center. Include the full travel envelope, cable bend allowance and access for replacement.
- 02
Review the axis state sequence
Specify enable, home, move, dwell, stop and fault recovery. State what the host should read and command at each stage.
- 03
Accept a complete working configuration
Test with the selected drive, cable and representative load. Record drawing, firmware and controller settings so the evaluated axis can be reproduced.
Define the inspection and release package before fixing the sample acceptance criteria.

Engineering FAQ
Is a controller included?
The supply scope is defined in the quotation. State whether you need a mechanical cylinder, an assembly with a motor, or a reviewed motor-and-drive combination. Include the host interface and available power supply.
Can the cylinder hold a load without power?
Do not assume that it can. Supply the load direction, permitted drift and required power-loss behavior. A brake, support or other holding arrangement may need separate evaluation.
What defines a repeatable replacement unit?
A controlled mechanical drawing, defined electrical pinout, motor and feedback identification, and applicable controller settings. Include the acceptance procedure and any configuration-specific calibration in the release package.
