Airtac ACQD Double Acting Compact Cylinder ACQD63X15SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X15SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø63mm 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 ACQD63X15SB
The AirTAC ACQD63X15SB is a double-acting JIS compact cylinder featuring a piston rod extending from both ends. Because a rod occupies each chamber, the annular area is identical in both directions, yielding perfectly equal push and pull forces of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa. This symmetry is ideal for applications requiring consistent bi-directional thrust without force imbalance.
The twin 20mm rods resist rotation and provide an extended guide length, allowing you to carry a tooling platform directly without needing a separate external guide. This specific configuration includes a built-in magnet (-S) for use with reed or solid-state switches, and male M18x1.5 rod-end threads (-B) for direct mounting. Deceleration is handled by fixed NBR elastomer bumpers at both ends, keeping the overall body compact.
Airtac ACQD Double Acting Compact Cylinder ACQD63X15SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X15SB |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 15 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 ACQD63X15SB Is Used
Symmetric Transfer Pusher
Drives a packaging carton transfer head on a 15mm stroke, utilizing the equal push and pull forces to accelerate and retract loads with identical momentum on a conveyor line.
Twin-Guided Part Lifter
Lifts small machined components out of a CNC fixture, relying on the dual 20mm rods to prevent jaw rotation without adding a bulky external linear guide.
Dual-Station Actuation
Uses the second protruding rod end to trigger a mechanical flag on an assembly machine, confirming stroke completion while the primary side drives the main workpiece.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X15SB the Right Cylinder?
Selecting this 63mm bore involves comparing its 1401.5N force at 0.5MPa against adjacent sizes: a 50mm bore provides 824.6N, while an 80mm bore yields 2267.8N. This makes the ACQD63X15SB the right choice when your application demands roughly 1.4kN of symmetric thrust within a compact footprint. If your mechanism only requires unidirectional push force and lacks a rigid guide, a single-rod ACQ cylinder might suffice. Conversely, if your load demands high lateral rigidity, a guided TACQ series could be more appropriate. Confirm your ordering essentials: 15mm stroke, PT1/4 port, male M18x1.5 rod threads, and the integrated magnet.
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 ACQD63X15SB FAQ
It delivers equal push and pull forces of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa, with a maximum capacity of 286kgf at 1.0MPa. Push equals pull because the double-rod design creates the same annular piston area in both directions. The maximum standard stroke available for this 63mm bore is 100mm.
It uses fixed NBR elastomer bumpers at both ends for end-of-stroke damping, which are not adjustable; for high kinetic energy loads, add an external shock absorber. A plain ACQD does not hold position when air pressure is lost, so for fail-safe load holding, you must install an external rod lock or pilot-operated check valve.
