Airtac ACQD Double Acting Compact Cylinder ACQD63X40SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X40SB 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 ACQD63X40SB
The AirTAC ACQD63X40SB is a double-acting JIS compact cylinder featuring twin rods that exit both ends of the body. Because a rod occupies each chamber, the annular piston area is identical in both directions, yielding perfectly equal push and pull forces of 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa. This symmetry is ideal for applications requiring consistent bi-directional thrust up to a maximum of 286 kgf.
Equipped with an -S magnet and -B male rod threads (M18x1.5), it couples directly to loads and supports both reed and solid-state switches via its integrated sensor groove. The Ø20mm twin rods provide extended guide length and resist torsion without needing an external guide. Fixed NBR elastomer bumpers absorb end-of-stroke impact, while the PT1/4 port handles pneumatic input.
Airtac ACQD Double Acting Compact Cylinder ACQD63X40SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X40SB |
|---|---|
| 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 ACQD63X40SB Is Used
Symmetric Transfer Arms
Drives a dual-ended pick-and-place arm in packaging machinery, using the equal push and pull thrust to move products smoothly in both directions without momentum bias.
Twin-Guided Pusher
Acts as a rotary-resistant pusher on a CNC machining cell, where the twin Ø20mm rods prevent tool deflection during part ejection.
Dual-Station Actuation
Powers a dual-station clamping fixture in an assembly line, using the second rod end to drive a secondary mechanical flag or load simultaneously.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X40SB the Right Cylinder?
For a 40mm stroke requirement, this 63mm bore delivers 1401.5 N at 0.5 MPa. If less force is needed, the 50mm bore provides 824.6 N, or step up to the 80mm bore for 2267.8 N. Choose a single-rod ACQ if equal push/pull is unnecessary, or a guided TACQ for heavy lateral loads. Order by specifying the ACQD63X40SB model, PT1/4 port, M18x1.5 male rod, and confirm your switch type.
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 ACQD63X40SB FAQ
The ACQD63X40SB generates equal push and pull forces of 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa, with a maximum capacity of 286 kgf. Push and pull are equal because the double-rod design creates identical annular areas on both sides. The standard stroke max for this 63mm bore is 100mm. It features a PT1/4 port and an M18x1.5 male rod end.
The twin rods resist rotation and extend guide length, while the second rod end can drive a sensor flag. The -S magnet works with reed or electronic solid-state switches. For stopping, it uses fixed NBR elastomer bumpers, not adjustable air cushions. Note that a plain ACQD does not hold position on air loss; use an external rod lock or pilot check valve for fail-safe holding.
