Airtac ACQD Double Acting Compact Cylinder ACQD20X15B
The AirTAC ACQD Double Acting Compact Cylinder ACQD20X15B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø20mm bore and 15mm 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 ACQD20X15B
The AirTAC ACQD20X15B is a double-acting JIS compact cylinder featuring a twin-rod design where a piston rod protrudes from both ends. Because a rod occupies both internal chambers, the effective annular area is identical in each direction, yielding equal push and pull forces of 117.8N at 0.5MPa and 164.9N at 0.7MPa. The dual rods resist rotation and provide a longer guide length, allowing it to carry a small tool platform without needing a separate external guide.
This 20mm bore model has a 15mm stroke and ships with a male-thread piston rod end (M8x1.25) for direct load coupling. It features fixed TPU elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions. The body includes magnetic-switch grooves, although this specific configuration omits the internal magnet. Operating pressure ranges from 0.15-1.0MPa, and the standard PT tapered ports are M5x0.8.
Airtac ACQD Double Acting Compact Cylinder ACQD20X15B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD20X15B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø20 mm |
| Stroke | 15 mm |
| Acting type | Double acting, double rod |
| Port size | M5×0.8 |
| Rod end thread | M5×0.8 female / M8×1.25 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 (Ø20mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 118 N | 118 N |
| 0.7 MPa | 165 N | 165 N |
| Max (@1.0 MPa) | 24 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 ACQD20X15B Is Used
Symmetric Transfer Unit
Drives a parts shuttle in packaging machinery where equal push and pull forces ensure consistent cycle timing in both directions without momentum drift.
Twin-Guided Pusher
Pushes product along a conveyor using the dual-rod structure to prevent platform twisting, eliminating the need for an external linear guide rail.
Dual-Station Actuation
Actuates a secondary mechanism or sensor flag from the rear rod end on an electronics assembly station while the main rod drives the primary tooling.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD20X15B the Right Cylinder?
When sizing this 20mm bore actuator, consider the adjacent bores: the 16mm variant provides 75.4N, while the 25mm offers 188.9N at 0.5MPa. If your application requires unequal extension and retraction forces, a single-rod ACQ cylinder is more appropriate. For loads needing precise anti-rotation over a long stroke, a guided TACQ cylinder might be a better fit. To order, confirm the 20mm bore, 15mm stroke, and the -B male rod thread option.
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 ACQD20X15B FAQ
This cylinder exerts equal push and pull forces of 117.8N at 0.5MPa and 164.9N at 0.7MPa, with a maximum force of 24kgf at 1.0MPa. Push and pull forces are equal because the twin rods create the same annular piston area in both chambers. The maximum standard stroke available for this 20mm bore is 100mm.
No, a plain ACQD does not hold position when air is lost. The rod will drift and the fixed TPU elastomer bumper only decelerates the load near the stroke end. For fail-safe load holding, you must install an external rod lock or a pilot-operated check valve.
