Airtac ACQD Double Acting Compact Cylinder ACQD20X50
The AirTAC ACQD Double Acting Compact Cylinder ACQD20X50 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø20mm bore and 50mm 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 ACQD20X50
The AirTAC ACQD20X50 is a double-acting JIS compact cylinder featuring a twin-rod design where a piston extends from both ends. Because a rod occupies each chamber, the annular area remains identical on both sides, yielding exactly 117.8N of force at 0.5MPa and 164.9N at 0.7MPa in either direction without push-pull disparity. The Ø10mm rods resist torsion and lengthen guide support, eliminating the need for an external anti-rotation bracket.
This 20mm bore unit includes fixed TPU elastomer bumpers at both ends to absorb impact energy rather than relying on adjustable air cushions. The body retains magnetic-switch grooves for tracking, though this specific configuration ships without a magnet. Operating at speeds of 30-500mm/s within a -20 to +70°C range, it uses M5x0.8 porting and a standard PT thread form.
Airtac ACQD Double Acting Compact Cylinder ACQD20X50 Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD20X50 |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø20 mm |
| Stroke | 50 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 ACQD20X50 Is Used
Symmetric Transfer
Drives a dual-sided pick-and-place arm in electronics assembly, using the equal push and pull to maintain balanced cycle times.
Twin-Guided Pusher
Pushes small cartons on a packaging conveyor without twisting, relying on the two rods to resist rotational torque.
Dual-Station Actuation
Actuates two separate clamps simultaneously on a test fixture, using both rod ends to drive independent loads.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD20X50 the Right Cylinder?
Providing a maximum 24kgf at 1.0MPa, this 50mm stroke model is sized between the smaller ACQD16 (75.4N at 0.5MPa) and the larger ACQD25 (188.9N at 0.5MPa). If your application only requires unidirectional thrust where pull force can be lower, a single-rod ACQ20 cylinder saves space. For heavier lateral loads requiring a longer guide bushing, a guided TACQ cylinder provides superior torsional rigidity. Confirm you need the default female M5x0.8 rod-end thread and standard PT porting 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 ACQD20X50 FAQ
It delivers an equal push and pull force of 117.8N at 0.5MPa and 164.9N at 0.7MPa, with a maximum capacity of 24kgf 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 for this 20mm bore is 100mm.
It uses fixed TPU elastomer bumpers at both ends to decelerate the piston, not adjustable air cushions. A plain ACQD does not hold its load if air pressure is lost; the rod will drift. For fail-safe load holding, an external rod lock or pilot-operated check valve is required.
