Airtac ACQD Double Acting Compact Cylinder ACQD50X300S
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X300S is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm bore and 300mm 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 ACQD50X300S
The ACQD50X300S is a double-acting JIS compact cylinder featuring a 50mm bore and an extended 300mm stroke. Because twin Ø20mm rods protrude from both ends, the annular piston area is identical in each direction. This geometry yields perfectly equal push and pull forces of 824.6N at 0.5MPa and 1154.5N at 0.7MPa, enabling perfectly symmetric cycling without force drop-off.
This made-to-order long-stroke variant utilizes a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. The integrated -S piston magnet pairs with reed or solid-state electronic switches via the body's sensor grooves. Operating pressure spans 0.15-1.0MPa, and the PT1/4 porting ensures robust pneumatic supply delivery.
Airtac ACQD Double Acting Compact Cylinder ACQD50X300S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD50X300S |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 300 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 ACQD50X300S Is Used
Symmetric Transfer Conveyor
Drives a dual-sided pusher on a packaging conveyor, using the equal bidirectional force to move cartons smoothly in both directions without momentum spikes.
Twin-Guided Pick & Place
Actuates a small tooling platform on an electronics assembly machine, relying on the two rods to prevent rotational drift during vertical component insertion.
Dual-Station Actuation
Powers a secondary sensor flag or clamp on a woodworking indexer using the rear rod end, saving space by driving two functions from one compact body.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X300S the Right Cylinder?
When sizing this 50mm bore unit, a smaller Ø40 version provides 527.8N at 0.5MPa, while stepping up to Ø63 yields 1401.5N at 0.5MPa. Choose this 300mm configuration only when extended travel is mandatory, as it exceeds the 100mm standard maximum. If your mechanism requires heavy lateral load support beyond what the twin rods offer, an external guided TACQ unit fits better. Confirm the female M10x1.5 rod-end thread and PT1/4 ports when finalizing your BOM.
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 ACQD50X300S FAQ
This 50mm bore cylinder provides equal push and pull forces of 824.6N at 0.5MPa and 1154.5N at 0.7MPa, with a maximum capacity of 168kgf at 1.0MPa. The 300mm stroke is a made-to-order long-stroke variant exceeding the 100mm standard maximum for this bore size.
No, a plain ACQD does not hold position on air loss. The fixed NBR bumper only decelerates the piston near stroke end, so the rod will drift. For fail-safe load holding, you must add an external rod lock or a pilot-operated check valve.
