Airtac ACQD Double Acting Compact Cylinder ACQD50X200SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X200SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm bore and 200mm 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 ACQD50X200SB
The AirTAC ACQD50X200SB is a double-acting JIS compact cylinder featuring twin rods that exit both ends of its riveted C-clip body. Because a shaft occupies each chamber, the annular area remains identical in either direction, generating equal push and pull forces of 824.6N at 0.5 MPa and 1154.5N at 0.7 MPa. This symmetric thrust is ideal for balanced transfer cycles, while the dual-shaft geometry resists torsion and extends guide support without needing a separate external anti-rotation bracket.
This 50mm bore unit is configured with a male M18x1.5 rod-end thread for direct load coupling, a built-in piston magnet (-S) for position sensing, and PT1/4 fluid ports. The 200mm stroke is a made-to-order long-stroke variant exceeding the 100mm standard maximum. Deceleration is handled by fixed NBR elastomer bumpers at both ends, and the integrated magnet works seamlessly with reed or solid-state electronic switches.
Airtac ACQD Double Acting Compact Cylinder ACQD50X200SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD50X200SB |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 200 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 ACQD50X200SB Is Used
Symmetric Transfer Shuttle
Drives a packaging shuttle back and forth with equal 824.6N force in both directions, ensuring consistent cycle timing without thrust asymmetry.
Twin-Guided Tooling Platform
Carries a CNC machining fixture on the male M18x1.5 rod end, relying on the second protruding shaft to prevent rotational drift during clamping.
Dual-Station Actuation
Uses both rod ends on an electronics assembly rig to trigger a sensor flag on one side while moving a primary load on the other.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X200SB the Right Cylinder?
Choosing this 50mm bore provides 824.6N of equal bidirectional thrust at 0.5 MPa. If your application requires less force, the neighboring Ø40 bore yields 527.8N, whereas stepping up to the Ø63 bore provides 1401.5N. For tasks needing asymmetric push strength where pull force can be lower, a single-rod ACQ cylinder is more appropriate. If extreme lateral rigidity is needed beyond the dual-shaft guidance, consider a guided TACQ model. Confirm ordering essentials: this ACQD50X200SB specifies a 200mm stroke, -S magnet, and -B male M18x1.5 rod thread.
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 ACQD50X200SB FAQ
It delivers equal push and pull forces of 824.6N at 0.5 MPa and 1154.5N at 0.7 MPa, with a maximum holding capacity of 168kgf at 1.0MPa. Push and pull forces are identical because the twin rods create the same annular area in both chambers. The 200mm stroke is a long-stroke variant exceeding the 100mm standard maximum for this bore. It features a PT1/4 port and a male M18x1.5 piston rod thread.
Deceleration is managed by fixed NBR elastomer bumpers at both ends, which are not adjustable, so external shock absorbers may be needed for high-energy approaches. The -S option includes a piston magnet compatible with reed or electronic solid-state switches. A plain cylinder does not hold its load if air pressure is lost; for fail-safe positioning, an external rod lock or pilot-operated check valve is required.
