Airtac ACQD Double Acting Compact Cylinder ACQD63X50SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X50SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø63mm 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 ACQD63X50SB
The AirTAC ACQD63X50SB is a double-acting JIS compact cylinder featuring twin 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. This symmetric thrust is ideal for balanced transfer cycles, while the parallel rods resist rotation and extend guiding length without needing a separate external guide.
Equipped with an S magnet and B male threads, this 63mm bore variant couples directly to your load via an M18x1.5 male rod end. It features a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. The integrated piston magnet works seamlessly with both reed and solid-state electronic switches installed in the body grooves. Note that a plain compact cylinder drifts when air is lost; use an external rod lock or pilot check valve if fail-safe holding is required.
Airtac ACQD Double Acting Compact Cylinder ACQD63X50SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X50SB |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 50 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 ACQD63X50SB Is Used
Symmetric Transfer Shuttle
Drives a packaging line shuttle where the identical push and pull thrust of 1962.2N at 0.7MPa ensures consistent dwell times in both travel directions without momentum variations.
Twin-Guided Tooling Platform
Carries a multi-station machining fixture on the twin rods, utilizing the extended guide length to resist rotational torque without adding a bulky external linear bearing.
Dual-End Actuation
Operates a stamping press feed mechanism where the primary M18x1.5 male rod end drives the press, while the opposite rod end actuates a solid-state sensor flag for timing.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X50SB the Right Cylinder?
For sizing both ways, a 50mm bore ACQD yields 824.6N at 0.5MPa, while an 80mm bore provides 2267.8N at 0.5MPa. This 63mm model provides a robust 1401.5N at 0.5MPa, fitting perfectly between them for medium-duty symmetric actuation. Choose a single-rod ACQ if your application only requires standard unbalanced push force or lacks space for a second rod. If your payload demands heavy lateral support beyond what the twin rods offer, consider a guided TACQ cylinder. To order, confirm the 50mm stroke, PT1/4 port, M10x1.5 female thread, and the M18x1.5 male rod end.
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 ACQD63X50SB FAQ
The ACQD63X50SB 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 twin rods create identical annular areas in both chambers. The maximum standard stroke for a 63mm bore is 100mm. It features a PT1/4 port, an M10x1.5 female rod-end thread, and an M18x1.5 male rod-end thread.
It uses a fixed NBR elastomer bumper at each end to absorb end-of-stroke impact; it is not an adjustable air cushion. The built-in S magnet is compatible with both reed and solid-state electronic switches. A plain compact cylinder does not hold its load if air pressure is lost; for fail-safe position holding, you must install an external rod lock or pilot-operated check valve.
