Airtac ACQD Double Acting Compact Cylinder ACQD20X90B
The AirTAC ACQD Double Acting Compact Cylinder ACQD20X90B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø20mm bore and 90mm 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 ACQD20X90B
The AirTAC ACQD20X90B is a double-acting JIS compact cylinder where a piston rod extends from both ends, providing identical push and pull thrust of 117.8N at 0.5MPa. Because the rod occupies both internal chambers, the annular area stays uniform in either direction, ensuring symmetric cycle forces. This 20mm bore unit runs at speeds from 30-500mm/s and features a 90mm stroke.
Twin rods drastically increase guide length and naturally resist torsion, letting you mount a small tool platform directly without needing an external anti-rotation guide. This variant includes male M8x1.25 rod-end threads (-B) for direct load coupling, M5x0.8 pneumatic ports, and fixed TPU elastomer bumpers at both ends for end-of-stroke deceleration.
Airtac ACQD Double Acting Compact Cylinder ACQD20X90B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD20X90B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø20 mm |
| Stroke | 90 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 ACQD20X90B Is Used
Symmetric Transfer Pusher
Drives a dual-sided pick-and-place head in electronics assembly, using the equal thrust to push and retract components with identical 117.8N force.
Twin-Guided Tool Platform
Carries a small machining fixture on a packaging line, relying on the two protruding rods to prevent torsion without adding a separate external guide rail.
Dual-Station Actuation
Indexes a secondary sensor flag or second load from the opposite rod end on a textile machine, synchronizing two processes from one compact body.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD20X90B the Right Cylinder?
Select this 20mm bore if your mechanism requires 117.8N of bidirectional thrust at 0.5MPa. Stepping down to a 16mm bore drops the equal push/pull force to 75.4N, while moving up to a 25mm bore raises it to 188.9N. If your application only needs standard single-direction actuation, the standard ACQ series is more economical, but choose this ACQD when twin-rod guiding or a secondary rod end is mandatory. Confirm your ordering needs: this 90mm stroke is within the 100mm maximum, and the -B male thread option is specified.
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 ACQD20X90B FAQ
It delivers an equal push and pull force of 117.8N at 0.5MPa and 164.9N at 0.7MPa, with a maximum capacity of 24kgf at 1.0MPa. Push and pull forces are identical because the double-rod design creates the same annular area in both directions. The maximum standard stroke available for this 20mm bore is 100mm.
It uses fixed TPU elastomer bumpers at both ends for impact absorption, not adjustable air cushions. Because it is a standard compact cylinder, it will not hold a load if air pressure is lost; for fail-safe positioning, you must install an external rod lock or pilot-operated check valve.
