Airtac ACQD Double Acting Compact Cylinder ACQD25X45B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD25X45B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø25mm 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 ACQD25X45B
The AirTAC ACQD25X45B is a double-acting JIS compact cylinder where a Ø12mm piston rod protrudes from both ends. Because a rod occupies each working chamber, the effective annular area is identical in both directions. This yields equal push and pull forces of 188.9N at 0.5MPa and 264.5N at 0.7MPa, enabling perfectly symmetric cycle movements.
The twin rods resist torsional load and provide a longer guide length, eliminating the need for a separate external anti-rotation guide. It features a fixed TPU elastomer bumper at each end for end-of-stroke deceleration. This B-option variant includes a male M10x1.25 rod-end thread for direct load coupling, while the body retains magnetic-switch grooves for future sensor addition.
Airtac ACQD Double Acting Compact Cylinder ACQD25X45B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD25X45B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø25 mm |
| Stroke | 45 mm |
| Acting type | Double acting, double rod |
| Port size | M5×0.8 |
| Rod end thread | M6×1.0 female / M10×1.25 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 (Ø25mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 189 N | 189 N |
| 0.7 MPa | 264 N | 264 N |
| Max (@1.0 MPa) | 39 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 ACQD25X45B Is Used
Symmetric Transfer Pusher
Drives a twin-guided pusher on a packaging line, using the equal push and pull forces to maintain consistent indexing without momentum drift.
Dual-Station Actuation
Powers a dual-station clamping fixture on a CNC machine, using the second protruding rod end to drive a secondary stop or sensor flag.
Anti-Rotation Gripper
Actuates a pick-and-place gripper in electronics assembly, relying on the torsional resistance of the dual rods to keep the tool platform perfectly level.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD25X45B the Right Cylinder?
Providing 188.9N of force at 0.5MPa, this 25mm bore sits between the 20mm option (117.8N) and the 32mm option (301.6N) for sizing bidirectional loads. The 45mm stroke is well within the 100mm maximum standard for this bore. If your mechanism only requires a single extending rod or demands a guided slide, a standard ACQ or TACQ series fits better. Confirm your build needs the male M10x1.25 thread, M5x0.8 port, and note this unit lacks a sensor magnet.
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 ACQD25X45B FAQ
It delivers an equal push and pull force of 188.9N at 0.5MPa and 264.5N at 0.7MPa, with a maximum holding force of 39kgf at 1.0MPa. Push and pull forces are identical because the twin rods create the same annular area in both chambers. The maximum standard stroke for a 25mm bore is 100mm.
It uses fixed TPU elastomer bumpers at both ends to absorb impact, not adjustable air cushions. It does not hold its load if air pressure is lost; the rod drifts and the bumper only decelerates near the stroke end. For fail-safe holding, an external rod lock or pilot-operated check valve is required.
