Airtac ACQD Double Acting Compact Cylinder ACQD20X45S
The AirTAC ACQD Double Acting Compact Cylinder ACQD20X45S is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø20mm bore and 45mm 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 ACQD20X45S
The AirTAC ACQD20X45S is a double-acting JIS compact cylinder featuring twin Ø10mm rods exiting both ends. Because a rod occupies each chamber, the annular area is identical in both directions, yielding equal push and pull forces of 117.8N at 0.5MPa and 164.9N at 0.7MPa. The 45mm stroke operates at speeds between 30-500mm/s within a riveted C-clip body.
This symmetrical force output enables perfectly balanced advance and retract cycles. The dual rods inherently resist rotation and provide an extended guide length, eliminating the need for an external anti-rotation block while allowing the second rod end to drive a sensor flag or secondary tool. Fixed TPU bumpers absorb end-of-stroke impact, and the -S piston magnet interfaces with reed or solid-state switches via the body grooves.
Airtac ACQD Double Acting Compact Cylinder ACQD20X45S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD20X45S |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø20 mm |
| Stroke | 45 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 ACQD20X45S Is Used
Symmetric Transfer Pusher
Drives a dual-sided conveyor diverter where equal 117.8N push and pull forces keep the transfer arm perfectly balanced during product sorting.
Twin-Guided Stamping Tool
Mounts a small stamping head on a CNC press, using the inherent anti-rotation of the double rods to maintain tool alignment without an external guide.
Dual-Station Actuator
Powers a two-station clamping fixture on an automated assembly machine, using the second rod end to trigger a reed sensor flag for cycle confirmation.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD20X45S the Right Cylinder?
Select this 20mm bore for symmetric 117.8N cycles; stepping down to the 16mm bore drops force to 75.4N, while the 25mm bore raises it to 188.9N. Choose a single-rod ACQ if push force must exceed pull force, or a guided TACQ when lateral loads exceed the twin rods' capacity. Confirm the 45mm stroke, M5x0.8 port, female M5x0.8 rod thread, and the -S magnet option when ordering.
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 ACQD20X45S FAQ
It delivers equal push and pull forces of 117.8N at 0.5MPa and 164.9N at 0.7MPa, with a maximum capacity of 24kgf at 1.0MPa. Push equals pull because the twin rods create identical annular areas on both sides. The 45mm stroke is within the 100mm maximum standard stroke limit for this 20mm bore.
It uses fixed TPU bumpers at both ends to absorb impact, not adjustable air cushions. For high energy cycles, add an external shock absorber. A plain ACQD does not hold position on air loss; for fail-safe holding, install an external rod lock or pilot-operated check valve.
