Airtac ACQD Double Acting Compact Cylinder ACQD20X100B
The AirTAC ACQD Double Acting Compact Cylinder ACQD20X100B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø20mm bore and 100mm 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 ACQD20X100B
The AirTAC ACQD20X100B is a double-acting JIS compact cylinder featuring twin rods that exit from both body ends. Because a piston rod occupies each chamber, the effective annular area is identical in both directions, yielding equal push and pull forces of 117.8N at 0.5MPa and 164.9N at 0.7MPa. This symmetry is ideal for applications needing perfectly balanced bidirectional cycles. The Ø10mm twin rods resist rotation and provide a longer guide length, allowing you to carry a small tool platform without needing an external anti-rotation guide.
This specific 20mm bore, 100mm stroke variant includes the -B male piston rod thread (M8x1.25) for direct load coupling. It uses M5x0.8 pneumatic ports and relies on fixed TPU elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions. The body retains integrated magnetic-switch grooves, but note this specific model ships without a magnet. Operating pressure spans 0.15-1.0MPa, with a proof pressure of 1.5MPa and a speed range of 30-500mm/s.
Airtac ACQD Double Acting Compact Cylinder ACQD20X100B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD20X100B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø20 mm |
| Stroke | 100 mm |
| Acting type | Double acting, double rod |
| Port size | M5×0.8 |
| Rod end thread | M5×0.8 female / M8×1.25 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 (Ø20mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 118 N | 118 N |
| 0.7 MPa | 165 N | 165 N |
| Max (@1.0 MPa) | 24 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 ACQD20X100B Is Used
Twin-Guided Pusher
Drives a precision part pusher in electronics assembly, using the dual rods to prevent platform yaw without an external guide rail.
Symmetric Transfer Unit
Powers a symmetric pick-and-place transfer mechanism where equal push and pull forces ensure consistent dynamic motion in both travel directions.
Dual-Station Actuation
Actuates a dual-station packaging clamp, using the second protruding rod end to mechanically trigger a mechanical flag or secondary mechanism simultaneously.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD20X100B the Right Cylinder?
When sizing this 20mm bore, consider the neighboring standard bores. Dropping to a 16mm bore reduces the equal bidirectional force to 75.4N at 0.5MPa, while stepping up to a 25mm bore increases it to 188.9N at 0.5MPa. If your load strictly requires unbalanced push force greater than pull, a single-rod ACQ cylinder is a better choice. For heavier radial loads exceeding the twin rods' guide capacity, a guided TACQ slide cylinder provides superior support. To order, confirm the 100mm stroke, the -B male M8x1.25 rod end, and your required PT port fittings.
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 ACQD20X100B FAQ
It delivers an equal push and pull force of 117.8N at 0.5MPa and 164.9N at 0.7MPa, with a maximum force of 24kgf at 1.0MPa. Push and pull forces are identical because the double-rod design creates the same effective annular area in both chambers. The maximum standard stroke for this 20mm bore is 100mm, and operating pressure is 0.15-1.0MPa.
It uses fixed TPU elastomer bumpers at both ends to absorb impact near stroke completion, meaning there is no adjustable air cushion. For high kinetic energy loads, you should add an external shock absorber or slow the approach speed. Additionally, a plain ACQD does not hold its position if air is lost; for fail-safe holding, an external rod lock or pilot-operated check valve is required.
