Airtac ACQD Double Acting Compact Cylinder ACQD63X45SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X45SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø63mm 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 ACQD63X45SB
The AirTAC ACQD63X45SB is a double-acting JIS compact cylinder with two Ø20mm piston rods extending from both ends. Because a rod occupies each chamber, the effective annular area is identical in both directions, yielding equal push and pull forces of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa. The twin rods inherently resist rotation and provide a longer guide length, allowing a tool platform to be carried directly without needing an external anti-rotation guide.
This 63mm bore variant features a PT1/4 port and a male M18x1.5 rod-end thread (-B) that couples directly to your load. It includes the -S magnet for position sensing, compatible with reed or solid-state switches. Deceleration is handled by fixed NBR elastomer bumpers at both ends. Note that a standard ACQD does not hold position on air loss; an external rod lock or pilot check valve is required for fail-safe holding.
Airtac ACQD Double Acting Compact Cylinder ACQD63X45SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X45SB |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 45 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 ACQD63X45SB Is Used
Twin-Guided Tool Platform
Drives a machining fixture on a CNC lathe, using the dual rods to maintain precise alignment and resist rotational torque during clamping.
Symmetric Transfer Pusher
Indexes cartons on a packaging line where equal push and pull forces ensure consistent forward placement and rearward retraction without drift.
Dual-Station Actuation
Simultaneously operates two separate pneumatic presses in an electronics assembly tester, using both rod ends to drive independent loads.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X45SB the Right Cylinder?
For sizing, the neighbouring 50mm bore yields 824.6N at 0.5MPa, while the 80mm bore provides 2267.8N at 0.5MPa. This 63mm unit delivers 1401.5N at 0.5MPa, making it the right fit when the smaller bore lacks thrust. If your application only needs one-sided actuation and higher forward force, a single-rod ACQ cylinder might be better, but for symmetric cycles and anti-rotation, this ACQD is ideal. The 45mm stroke is a non-standard length but remains within the 100mm maximum standard stroke limit. Confirm the male M18x1.5 thread and PT1/4 port 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 ACQD63X45SB 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 rod occupies both chambers, creating identical annular areas. The 45mm stroke is within the 100mm maximum standard stroke limit for this 63mm bore.
No, a plain ACQD does not hold position when air is lost or a valve is centered; the rod will drift. The fixed NBR bumpers only decelerate the piston near stroke ends. For fail-safe holding, you must add an external rod lock or a pilot-operated check valve.
