Airtac ACQD Double Acting Compact Cylinder ACQD50X20H
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X20H is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm bore and 20mm stroke. The twin rods resist rotation and give equal push and pull force, so it carries and guides a tool platform without a separate anti-rotation guide.

About the Airtac ACQD Double Acting Compact Cylinder ACQD50X20H
The AirTAC ACQD50X20H is a double-acting JIS compact cylinder featuring a 50mm bore and 20mm stroke. A piston rod extends from both ends, creating matching annular areas that yield identical push and pull forces of 824.6N at 0.5MPa. This symmetric thrust is ideal for balanced cycling tasks.
Twin rods supply extended guiding length and high torsional resistance, allowing you to mount a tooling platform directly without needing an external anti-rotation guide. The body incorporates sensor grooves for reed or solid-state switches, though this specific unit ships without a magnet. Deceleration is handled by fixed NBR elastomer bumpers at both ends, and the PT1/4 port ensures adequate airflow for its 30-500mm/s speed range.
Airtac ACQD Double Acting Compact Cylinder ACQD50X20H Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD50X20H |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 20 mm |
| Acting type | Double acting, double rod |
| Port size | PT1/4 |
| Rod end thread | M10×1.5 female / M18×1.5 male (B) |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 500 mm/s |
| Cushion | Bumper (both ends) |
| Max standard stroke | Up to 100 mm |
Specifications follow the official AirTAC ACQD datasheet. A rod exits both ends, so both directions use the same annular area. Confirm against the product label before installation.
Theoretical Output Force (Ø50mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 825 N | 825 N |
| 0.7 MPa | 1155 N | 1155 N |
| Max (@1.0 MPa) | 168 kgf | |
Because a rod occupies both chambers, push and pull forces are EQUAL — the annular area applies in each direction. Actual usable force is lower due to friction; size with a safety margin.

Where the Airtac ACQD Double Acting Compact Cylinder ACQD50X20H Is Used
Symmetric Transfer Pusher
Drives a dual-sided transfer carriage on a packaging line where matching push and pull thrust prevents workpiece skewing during reversal.
Twin-Guided Press Tool
Mounts a small stamping or clamping fixture directly to the twin rods in an electronics assembly jig, utilizing the inherent torsional resistance.
Dual-Station Actuator
Uses the second protruding rod end to trigger a mechanical flag or secondary mechanism on a textile machine while the primary end executes the main work.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X20H the Right Cylinder?
Delivering 824.6N of equal bidirectional force at 0.5MPa, this 50mm bore unit sits comfortably between the 63mm bore (1401.5N) and the 40mm bore (527.8N) options. Choose the ACQD50X20H when your application requires exact symmetric thrust within a compact footprint and a 20mm stroke. If your mechanism only needs force in one direction, a single-rod ACQ series cylinder is more space-efficient. For heavier lateral loads requiring independent external guidance, a guided TACQ cylinder might be preferable. When ordering, confirm the PT1/4 port size and the default female M10x1.5 rod-end threading.
Quick checklist
- ✓ Equal force both ways at your pressure
- ✓ Anti-rotation needed (twin rods)?
- ✓ Both rod ends usable for tooling?
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Both rods share the load — keep force concentric.
- check Twin rods resist rotation but avoid heavy side load.
- check Handle the C-clip carefully; seat it fully in its groove.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACQD Double Acting Compact Cylinder ACQD50X20H FAQ
It provides equal push and pull forces of 824.6N at 0.5MPa and 1154.5N at 0.7MPa, with a maximum capacity of 168kgf at 1.0MPa. Push and pull forces are identical because the double-rod design creates the same annular area in both chambers. The maximum standard stroke available for this 50mm bore is 100mm.
It uses fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration, meaning there are no adjustable air cushions. A plain ACQ-type cylinder does not hold its load if air pressure is lost; the rod will drift. For fail-safe load holding, you must install an external rod lock or a pilot-operated check valve.
