Airtac ACQD Double Acting Compact Cylinder ACQD50X45
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X45 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm bore and 45mm 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 ACQD50X45
The AirTAC ACQD50X45 is a double-acting JIS compact cylinder where a Ø20 mm piston rod extends from both body ends. Because a rod occupies each chamber, the annular area is identical in both directions, yielding equal push and pull forces of 824.6 N at 0.5 MPa and 1154.5 N at 0.7 MPa. This 50 mm bore, 45 mm stroke unit uses PT1/4 ports and a default female M10x1.5 rod-end thread.
Twin rods inherently resist rotation and provide a longer guide length, allowing you to carry a small tool platform without adding an external anti-rotation guide. The fixed NBR elastomer bumpers at each end absorb end-of-stroke impact, while the body retains magnetic-switch grooves. Note that this specific configuration ships without a magnet, so position detection requires adding one separately.
Airtac ACQD Double Acting Compact Cylinder ACQD50X45 Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD50X45 |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 45 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 ACQD50X45 Is Used
Symmetric Transfer Pusher
Drives a dual-sided transfer arm on packaging conveyors where matching push and pull thrust prevents load twisting during rapid direction reversals.
Dual-Station Actuation
Simultaneously indexes two small fixture plates on an electronics assembly line using both rod ends to deliver synchronized motion.
Twin-Guided Tool Lift
Raises and lowers a light machining head on a CNC cell; the extra guide length from the second rod stabilizes the platform without external guides.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X45 the Right Cylinder?
At 0.5 MPa this 50 mm bore generates 824.6 N both ways; stepping down to a 40 mm bore yields 527.8 N, while stepping up to a 63 mm bore provides 1401.5 N. Choose this 45 mm stroke model for compact transfer tasks needing symmetric thrust within the 100 mm standard stroke limit. If your application only needs standard unidirectional pushing, a single-rod ACQ saves space, whereas a guided TACQ is better for heavy off-axis loads. Confirm you need the default female M10x1.5 rod thread and PT1/4 porting when ordering.
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 ACQD50X45 FAQ
It delivers equal push and pull forces of 824.6 N at 0.5 MPa and 1154.5 N at 0.7 MPa, with a maximum capacity of 168 kgf at 1.0 MPa. Push equals pull because the double-rod design presents the same annular area in both directions. The maximum standard stroke available for this 50 mm bore is 100 mm.
It uses fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration, which are not adjustable air cushions. A plain ACQD does not hold position if air pressure is lost; for fail-safe load holding, you must install an external rod lock or a pilot-operated check valve.
