Airtac ACQD Double Acting Compact Cylinder ACQD25X40SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD25X40SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø25mm bore and 40mm 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 ACQD25X40SB
The AirTAC ACQD25X40SB is a double-acting JIS compact cylinder featuring a twin-rod design where a piston extends from both body ends. Because a rod occupies each chamber, the annular areas match, generating identical 188.9N force at 0.5MPa and 264.5N at 0.7MPa in both directions. This symmetry is ideal for balanced push/pull cycles without force drop.
Twin Ø12mm rods resist rotation and lengthen the guide path, removing the need for an external anti-rotation guide. The second rod end can drive a sensor flag or mount a secondary tool. This SB configuration includes a male M10x1.25 rod thread for direct coupling, a built-in magnet for reed or solid-state switches, and fixed TPU bumpers for end-of-stroke deceleration.
Airtac ACQD Double Acting Compact Cylinder ACQD25X40SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD25X40SB |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø25 mm |
| Stroke | 40 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 ACQD25X40SB Is Used
Symmetric Transfer Arms
Drives a dual-sided pick-and-place arm in electronics assembly, using the second rod end to mirror a parallel gripper without torque twist.
Twin-Guided Pushers
Positions small metal stampings on a CNC machining center, relying on the twin rods to prevent binding during the 40mm extension.
Dual-Station Actuation
Actuates two separate test probes simultaneously from a single compact body in a semiconductor packaging fixture.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD25X40SB the Right Cylinder?
Select this 25mm bore for applications needing 188.9N (0.5MPa) or 264.5N (0.7MPa) of equal bidirectional force over a 40mm stroke. If lower force is acceptable, the 20mm bore yields 117.8N at 0.5MPa; for heavier loads, the 32mm bore provides 301.6N. Choose a single-rod ACQ if rotation is tolerated and only one working end is needed, or a guided TACQ for higher lateral loads. Confirm the male M10x1.25 thread and M5x0.8 port suit your setup.
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 ACQD25X40SB FAQ
It generates equal push and pull forces of 188.9N at 0.5MPa and 264.5N at 0.7MPa, with a maximum capacity of 39kgf at 1.0MPa. Push and pull match because the twin rods create identical annular piston areas. The maximum standard stroke for a 25mm bore is 100mm.
The double-rod structure inherently resists rotation and extends guide length. Fixed TPU bumpers decelerate the piston at both ends, though external shock absorbers are recommended for high-energy cycles. It does not hold position on air loss; use an external rod lock or pilot-operated check valve for fail-safe holding.
