Quick answer: use the ZHR-EC Series when you need a compact 12V brushless servo electric cylinder for 8-10mm stroke, 80-120N maximum push/pull force, RS232 communication, and 0.02mm repeatability in a small robot end effector, fixture or precision push/pull mechanism.

What Is a Servo Electric Cylinder?
A servo electric cylinder is a linear actuator designed for controlled push/pull motion. General linear actuators create motion in a straight line, while servo systems add feedback-based control of position, velocity or acceleration. In practical robotics language, a servo electric cylinder is the linear-motion counterpart to a compact servo joint: it turns electrical control into repeatable mechanical displacement.
ZHR-EC focuses on short travel rather than long-stroke industrial axis motion. The current models are compact 12V brushless servo electric cylinders with RS232 communication, 10mm/s running speed, and downloadable mechanical files for fast fixture evaluation.
When ZHR-EC Is the Right Fit
Choose a ZHR-EC servo electric cylinder when the mechanism needs a small controlled extension and retraction movement. Typical design situations include a miniature clamp, latch, probe, dispenser, gripper assist, compact slide, inspection fixture, or a small automation module where rotary joint packaging would create unnecessary linkage complexity.
- Use ZHR-EC for 8-10mm controlled linear stroke and 80-120N maximum push/pull force.
- Use ZHR-P when the axis needs rotary torque, shock tolerance, and planetary integrated joint behavior.
- Use ZHR-H when the rotary joint needs compact zero-backlash strain-wave precision.
If you are choosing across all ZHR product lines, start with the Product Selector, then open the ZHR-EC product page when the axis is clearly a short-stroke linear mechanism.
ZHR-EC Model Comparison
| Model | Stroke | Max Push/Pull Force | Stall Force | Voltage | Interface |
|---|---|---|---|---|---|
| ZHREC-T120-S10-BF | 10mm | 120N | 150N | 12V | RS232 |
| ZHREC-T120-S10-SF | 10mm | 120N | 150N | 12V | RS232 |
| ZHREC-T100-S08-SF | 8mm | 80N | 100N | 12V | RS232 |
All three models share 10mm/s running speed, 0.02mm repeatability, 1.2A peak current, and -10C to 80C operating temperature in the available catalog data. The main choice is therefore mechanical envelope, mounting style, stroke and force requirement.
Electric Cylinder vs Pneumatic Cylinder in Small Robotics
Pneumatic cylinders are simple and fast, but they need compressed air, valves and tubing. For a compact robot, mobile platform, desktop test fixture or small end effector, those support systems can be larger than the mechanism itself. A compact electric cylinder keeps the actuation electric and easier to package with other mechatronic components.
The decision is not that electric is always better. Pneumatics can still be attractive for high cycle speed and simple end-stop motion. ZHR-EC is stronger when the design calls for electrical integration, compact wiring, controlled short stroke, repeatable movement and downloadable CAD-style files during evaluation.
Selection Checklist for a Brushless Servo Electric Cylinder
- Confirm stroke first. ZHR-EC currently covers 8mm and 10mm catalog stroke options.
- Calculate required force with margin. Use 80N or 120N maximum push/pull force as the selection boundary, then check stall force separately.
- Check voltage and current budget. The series uses 12V with 1.2A peak current in the catalog data.
- Validate communication. Current listed models use RS232, so confirm controller compatibility before mechanical design freeze.
- Download the drawing package early. Use the ZHR-EC Spec Sheets and 3D files to verify mounting and clearance before sample ordering.

For a full motion system, treat ZHR-EC as the linear-motion member of the ZHR family. Use ZHR-H harmonic reducer joint motors for compact precision rotary joints, ZHR-P planetary integrated servo joint modules for high-shock rotary axes, and the integrated servo joint module guide when the axis is rotary instead of linear.
FAQ
What is the primary keyword for this page?
The primary keyword is servo electric cylinder. It captures both the product category and the buyer's intent to find a controlled electric cylinder rather than a generic linear actuator.
Is ZHR-EC a long-stroke linear actuator?
No. ZHR-EC is positioned for compact short-stroke movement. The current catalog data covers 8mm and 10mm stroke options, which is better suited to end effectors, small fixtures and compact mechatronic mechanisms than long travel axes.
Where can I download ZHR-EC drawings?
Open the ZHR-EC Series Spec Sheets for printable model data and use the downloads section on the ZHR-EC product page for available STEP, SLDPRT and PRT files.
