Airtac ACQD Double Acting Compact Cylinder ACQD63X40S
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X40S is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø63mm bore and 40mm 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 ACQD63X40S
The AirTAC ACQD63X40S is a double-acting JIS compact cylinder featuring twin rods that exit both ends of the body. Because a rod occupies both chambers, the effective annular area is identical in each direction, delivering equal push and pull forces of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa. This symmetry is ideal for applications requiring perfectly balanced bidirectional cycles.
The dual rods inherently resist rotation and provide an extended guide length, allowing you to mount a tool platform directly without adding a separate anti-rotation guide. The second rod end can simultaneously drive a sensor flag or a secondary load. It uses a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion, and the included -S magnet works seamlessly with reed or solid-state switches via the body grooves.
Airtac ACQD Double Acting Compact Cylinder ACQD63X40S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X40S |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 40 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 (Ø63mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | 1962 N |
| Max (@1.0 MPa) | 286 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 ACQD63X40S Is Used
Symmetric Transfer Shuttle
Drives a parts shuttle on an assembly line where equal push and pull forces ensure identical transit times for loading and unloading fixtures.
Twin-Guided Stripper Pusher
Pushes a stripper plate in a stamping press, using the dual rods to prevent platform rotation without needing an external guide pillar.
Dual-Station Actuation
Operates a dual-station clamping mechanism in a machining center, using the second protruding rod end to actuate a secondary position valve.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X40S the Right Cylinder?
At a 63mm bore, this cylinder yields 1401.5N of force both ways at 0.5MPa. If you need less push, the 50mm bore provides 824.6N, or for heavier loads, the 80mm bore offers 2267.8N. Choose this ACQD model when symmetric force and anti-rotation are required; a single-rod ACQ is better for unidirectional tasks, while a guided TACQ fits if you need external load bearing. Confirm your ordering essentials: standard 40mm stroke, PT1/4 port, Ø20 rod with M10x1.5 female rod-end thread, and the -S magnet 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 ACQD63X40S FAQ
It delivers an equal push and pull force of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa, with a maximum holding capacity of 286kgf at 1.0MPa. Push and pull forces are identical because the twin rods create the same annular area in both chambers. The maximum standard stroke available for this 63mm bore is 100mm.
The twin rods resist torsion and extend guide length, eliminating the need for a separate anti-rotation guide. The -S magnet option enables position detection using either reed or electronic solid-state switches in the body grooves. Deceleration is handled by fixed NBR elastomer bumpers at both ends, not adjustable air cushions.
