Airtac ACQD Double Acting Compact Cylinder ACQD50X90B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X90B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm 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 ACQD50X90B
The AirTAC ACQD50X90B is a double-acting JIS compact cylinder featuring twin rods that exit both ends of the body. Because a rod occupies each chamber, the annular area is identical in both directions, yielding equal push and pull forces of 824.6N at 0.5MPa and 1154.5N at 0.7MPa. This symmetric thrust is ideal for balanced actuation cycles. The extended guide length resists torsional deflection without needing an external guide rail.
This 50mm bore unit integrates a fixed NBR elastomer bumper at each end to soften end-of-stroke impacts, distinct from adjustable air cushions. It includes a male M18x1.5 piston rod end for direct load coupling. The body retains magnetic-switch grooves for position sensing, though this specific configuration ships without the internal magnet. Operating pressure spans 0.15-1.0MPa, and the PT1/4 port handles standard pneumatic supply.
Airtac ACQD Double Acting Compact Cylinder ACQD50X90B Technical Specifications

|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 90 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 (Ø50mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 825 N | 825 N |
| 0.7 MPa | 1155 N | 1155 N |
| Max (@1.0 MPa) | 168 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 ACQD50X90B Is Used
Symmetric Transfer Pusher
Drives a dual-sided conveyor diverter in packaging lines, utilizing the equal push and pull forces to reliably shuttle products in both directions without asymmetric speed drift.
Twin-Guided Tool Platform
Positions a small machining head on an automated assembly station, where the twin rods provide the necessary torsional resistance to prevent deflection during downward clamping.
Dual-Station Actuation
Actuates a secondary mechanism via the opposing rod end in a textile machine, simultaneously tensioning fabric while the primary side drives the main forming die.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X90B the Right Cylinder?
Selecting this 90mm stroke model provides 824.6N of thrust at 0.5MPa. If your application requires less force, the 40mm bore variant offers 527.8N; stepping up to the 63mm bore provides 1401.5N. Choose this twin-rod architecture when a load demands built-in anti-rotation support or a second rod end is needed to mount a sensor flag. A single-rod ACQ cylinder is preferable if you only need standard unidirectional thrust and want a lighter footprint. This variant includes the -B male M18x1.5 thread for straightforward mechanical attachment.
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 ACQD50X90B FAQ
This cylinder provides equal push and pull forces of 824.6N at 0.5MPa and 1154.5N at 0.7MPa, with a maximum load capacity of 168kgf at 1.0MPa. The push and pull forces are identical because the twin-rod design creates the same annular piston area in both chambers. It has a 90mm stroke (max standard stroke is 100mm), a 50mm bore, and features a male M18x1.5 rod-end thread.
No, a plain ACQD cylinder will drift if air pressure is lost or the valve is centered; an external rod lock or pilot-operated check valve is required for fail-safe load holding. For stopping, it uses fixed NBR elastomer bumpers at both ends to absorb end-of-stroke energy. It is not equipped with adjustable air cushions, so external shock absorbers are recommended for high-speed or high-energy loads.
