Airtac ACQD Double Acting Compact Cylinder ACQD50X175
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X175 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm bore and 175mm 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 ACQD50X175
The AirTAC ACQD50X175 is a double-acting JIS compact cylinder featuring twin rods that exit from both ends. Because a rod occupies each chamber, the effective annular area is identical in both directions, delivering equal push and pull forces of 824.6N at 0.5MPa and 1154.5N at 0.7MPa. This 175mm stroke is a made-to-order long-stroke variant, extending past the 100mm standard maximum for this 50mm bore.
The symmetrical rod layout resists rotation and provides a longer guide length, allowing you to carry a tool platform without needing an external anti-rotation guide. The second rod end can drive a sensor flag or a secondary load. It uses fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions. This specific configuration ships without a magnet, uses a PT1/4 port, and features a female M10x1.5 rod-end thread.
Airtac ACQD Double Acting Compact Cylinder ACQD50X175 Technical Specifications

| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 175 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 ACQD50X175 Is Used
Symmetric Transfer Conveyor
Drives a dual-sided pick-and-place head on a packaging line, utilizing the equal push and pull forces to move products consistently in both directions without thrust imbalance.
Twin-Guided Part Pusher
Ejects machined components from a CNC mill using the twin rods to prevent platform rotation over the extended 175mm travel, eliminating the need for a separate external guide rail.
Dual-Station Actuation
Powers a secondary mechanism via the rear rod end on an assembly machine, allowing one cylinder to simultaneously index a part fixture and trigger a downstream sensor flag.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X175 the Right Cylinder?
When sizing this 50mm bore, note the 824.6N force applies equally in both directions. If your application requires less force, stepping down to a 40mm bore yields 527.8N at 0.5MPa; if you need more thrust, the 63mm bore provides 1401.5N. Remember this 175mm unit is a nonstandard long-stroke variant exceeding the 100mm standard maximum. If load holding is required during air loss, a plain ACQD will drift, so you must integrate an external rod lock or pilot-operated check valve. For high-velocity cycles, add an external shock absorber since the fixed bumpers only decelerate near the stroke ends.
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 ACQD50X175 FAQ
The push and pull forces are equal at 824.6N @0.5MPa and 1154.5N @0.7MPa, with a maximum of 168kgf @1.0MPa. Push equals pull because the double-rod design creates the same annular area in both chambers. The 175mm stroke is a made-to-order long-stroke variant, exceeding the 100mm standard maximum for a 50mm bore.
Twin rods exiting both ends resist rotation and provide a longer guide length for tool platforms. Deceleration is handled by fixed NBR elastomer bumpers at each end, not adjustable air cushions; for high-energy cycles, add an external shock absorber. This model ships without a sensor magnet, though the body retains switch grooves for adding reed or solid-state sensors.
