Airtac B01-ACQD Special Cylinder B01-ACQD20X40
The AirTAC Airtac B01-ACQD Special Cylinder B01-ACQD20X40 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø20mm 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 B01-ACQD Special Cylinder B01-ACQD20X40
The B01-ACQD20X40 is an AirTAC JIS compact double-acting cylinder where a piston rod protrudes from both ends. Because a rod occupies each chamber, the annular area is identical in both directions, yielding perfectly equal push and pull forces of 117.8N at 0.5MPa and 164.9N at 0.7MPa. The B01- prefix denotes an application-dedicated variant of the base ACQD20X40, retaining identical mechanical specifications and dimensions.
Twin rods resist rotation and provide a longer guide length, allowing you to carry a small tool platform without needing an external anti-rotation guide. The second rod end can drive a sensor flag or a secondary load. It features a fixed TPU elastomer bumper at each end for end-of-stroke deceleration and operates at speeds from 30-500mm/s. The body includes magnetic-switch grooves, though this specific SKU ships without a magnet installed.
Airtac B01-ACQD Special Cylinder B01-ACQD20X40 Technical Specifications
| Model | Airtac B01-ACQD Special Cylinder B01-ACQD20X40 |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø20 mm |
| Stroke | 40 mm |
| Acting type | Double acting, double rod |
| Port size | M5×0.8 |
| Rod end thread | M5×0.8 female / M8×1.25 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 (Ø20mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 118 N | 118 N |
| 0.7 MPa | 165 N | 165 N |
| Max (@1.0 MPa) | 24 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 B01-ACQD Special Cylinder B01-ACQD20X40 Is Used
Symmetric Transfer Pusher
Drives a dual-sided transfer carriage on packaging lines where equal push and pull force prevents uneven wear on the tooling platform.
Twin-Guided Pick & Place
Lifts small electronic components using a secondary rod end to mount a sensor flag, relying on the twin rods to prevent jaw rotation.
Dual-Station Actuation
Powers a compact dual-station clamping fixture on CNC machinery, using the double-rod design to maintain precise angular stability.
Is the Airtac B01-ACQD Special Cylinder B01-ACQD20X40 the Right Cylinder?
Select this 20mm bore actuator when you need symmetric push/pull cycles up to 24kgf at 1.0MPa. Stepping down to a 16mm bore drops the force to 75.4N at 0.5MPa, while stepping up to a 25mm bore increases it to 188.9N. If your application requires push force to exceed pull force, a single-rod ACQ cylinder is a better fit. For higher side loads requiring external guidance, consider a guided TACQ model. Confirm the 40mm stroke, M5x0.8 port, and female M5x0.8 rod-end thread 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 B01-ACQD Special Cylinder B01-ACQD20X40 FAQ
It generates an equal push and pull force of 117.8N at 0.5MPa and 164.9N at 0.7MPa, with a maximum capacity of 24kgf at 1.0MPa. Push and pull forces are identical because the double-rod design creates the same annular area in both chambers. The maximum standard stroke for this 20mm bore is 100mm.
The B01- prefix indicates an application-dedicated, customer-specified variant of the standard ACQD20X40, remaining mechanically identical to the base model. A plain ACQ-type cylinder does not hold its load when air is lost; the rod drifts and the fixed TPU bumper only decelerates near the stroke end. For fail-safe holding, an external rod lock or pilot-operated check valve is required.
