Airtac ACQD Double Acting Compact Cylinder ACQD12X50SB
The AirTAC ACQD Double Acting Compact Cylinder ACQD12X50SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø12mm 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 ACQD12X50SB
The AirTAC ACQD12X50SB is a double-acting JIS compact cylinder featuring twin rods extending from both ends. Because a rod occupies each internal chamber, the effective annular area is identical on extension and retraction. This yields perfectly equal push and pull forces of 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa, enabling highly symmetric actuation cycles.
The dual-rod architecture inherently resists rotation and provides a longer guide length, allowing the unit to carry a small tool platform without needing an external anti-rotation guide. This 12mm bore model includes a built-in piston magnet for reed or solid-state sensing, and features M5x0.8 male rod-end threads for direct load coupling. Deceleration is handled by fixed TPU elastomer bumpers at each end.
Airtac ACQD Double Acting Compact Cylinder ACQD12X50SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD12X50SB |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø12 mm |
| Stroke | 50 mm |
| Acting type | Double acting, double rod |
| Port size | M5×0.8 |
| Rod end thread | M3×0.5 female / M5×0.8 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 50 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 (Ø12mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 42 N | 42 N |
| 0.7 MPa | 59 N | 59 N |
| Max (@1.0 MPa) | 9 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 ACQD12X50SB Is Used
Twin-Guided Micro Pusher
Drives a delicate electronic component placement head on a PCB assembly machine, using the dual rods to prevent platform yaw during extension.
Symmetric Transfer Unit
Picks and places small medical vials in a packaging line, leveraging the equal push and pull forces to maintain consistent cycle timing in both directions.
Dual-Station Actuation
Actuates a tiny secondary sensor flag on the rear rod end to confirm stroke completion on a semiconductor sorting handler, while the front rod drives the primary gripper.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD12X50SB the Right Cylinder?
This 12mm bore variant reaches the maximum standard stroke of 50mm for its size, generating 9 kgf at 1.0 MPa with equal force both ways. If your application requires less than 42.4N at 0.5MPa, a smaller bore is needed, while heavier loads demand stepping up to the 16mm bore (75.4N @0.5MPa). Choose a single-rod ACQ if you only need unidirectional push force and want to save space. Confirm your order specifies the M5x0.8 port, the -S magnet, and the -B male rod thread.
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 ACQD12X50SB FAQ
It delivers equal push and pull forces of 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa, with a maximum capacity of 9 kgf at 1.0 MPa. The push and pull values are identical because the twin rods create equal annular areas on both sides. This 12mm bore model has a 50mm stroke, which is the maximum standard stroke available for this bore size.
Deceleration is provided by fixed TPU elastomer bumpers at both ends, which are not adjustable. For high impact energies, use an external shock absorber. A plain ACQD does not hold position if air pressure is lost; the rod will drift. For fail-safe load holding, an external rod lock or pilot-operated check valve is required.
