Airtac ACQD Double Acting Compact Cylinder ACQD12X35B
The AirTAC ACQD Double Acting Compact Cylinder ACQD12X35B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø12mm bore and 35mm 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 ACQD12X35B
The AirTAC ACQD12X35B is a double-acting JIS compact cylinder where a Ø6 mm piston rod protrudes from both ends. Because a rod occupies both internal chambers, the effective annular area is identical in each direction. This yields perfectly equal push and pull forces of 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa, eliminating the force mismatch found in single-rod units.
The twin-rod architecture inherently resists rotation and extends the guide length, letting you mount a small tool platform directly without needing an external anti-rotation guide. This specific variant includes male M5x0.8 rod-end threads for direct coupling, fixed TPU elastomer bumpers for end-of-stroke deceleration, and M5x0.8 pneumatic ports. Note that this unit ships without a magnet, though the body retains sensor grooves for future switch additions.
Airtac ACQD Double Acting Compact Cylinder ACQD12X35B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD12X35B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø12 mm |
| Stroke | 35 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 ACQD12X35B Is Used
Twin-Guided Micro-Pusher
Drives a small electronics pick-and-place head where the second rod prevents platform twist during the 35 mm transfer stroke.
Symmetric Transfer Mechanism
Actuates a delicate 12 mm bore assembly fixture where equal push and pull forces are required to maintain balanced clamping cycles.
Dual-Station Actuation
Uses both rod ends simultaneously to index two separate light-load test stations on a PCB inspection machine.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD12X35B the Right Cylinder?
For this 12 mm bore, the 35 mm stroke fits well within the 50 mm maximum standard limit, delivering 42.4 N of symmetric force at 0.5 MPa. If you need slightly less push/pull capacity, the series lacks a smaller bore, so you would look at a single-rod ACQ12 variant; if you need more force, stepping up to the 16 mm bore raises the output to 75.4 N. Choose this -B male-threaded (M5x0.8) model for direct mechanical attachment, and remember that a plain double-rod cylinder drifts if air pressure is lost, so add an external rod lock for fail-safe holding.
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 ACQD12X35B FAQ
It delivers an equal push and pull force of 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa, with a maximum holding capacity of 9 kgf at 1.0 MPa. The operating pressure is 0.15-1.0 MPa, the stroke is 35 mm, and the maximum standard stroke available for this 12 mm bore is 50 mm. Push equals pull because the rod occupies both chambers, creating the same annular area in both directions.
The twin rods resist rotation and provide a longer guide length so no external guide is needed. It uses fixed TPU elastomer bumpers at both ends for deceleration rather than adjustable air cushions. This -B variant has male M5x0.8 rod threads, and while the body features magnetic-switch grooves, this specific model ships without a magnet, so reed or solid-state switches will not function unless a magnetized piston is installed.
