Airtac ACQD Double Acting Compact Cylinder ACQD100X40SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD100X40SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø100mm 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 ACQD100X40SB
The AirTAC ACQD100X40SB is a double-acting JIS compact cylinder featuring a 100mm bore and a 40mm stroke. Because twin Ø32mm rods exit both ends, the annular piston area remains identical in each direction. This yields perfectly balanced thrust, generating 3524.8N at 0.5MPa and 4934.8N at 0.7MPa for both extension and retraction. The -B option provides M26x1.5 male rod-end threads, coupling directly to your tooling.
Integrated NBR bumpers absorb impact at both stroke limits, as there is no adjustable air cushion. The -S magnet enables position sensing via reed or solid-state switches seated in the body grooves. Operating pressure spans 0.15-1.0MPa, and the PT3/8 porting handles the required airflow for cycles up to 500mm/s.
Airtac ACQD Double Acting Compact Cylinder ACQD100X40SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD100X40SB |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 40 mm |
| Acting type | Double acting, double rod |
| Port size | PT3/8 |
| Rod end thread | M20×2.5 female / M26×1.5 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 (Ø100mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3525 N | 3525 N |
| 0.7 MPa | 4935 N | 4935 N |
| Max (@1.0 MPa) | 719 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 ACQD100X40SB Is Used
Symmetric Transfer Pusher
Drives a dual-sided transfer carriage on packaging machinery where equal push and pull thrust prevents load biasing during rapid direction changes.
Twin-Guided Stamping Platform
Lowers a small stamping head on CNC fabrication lines; the twin rods resist torsional deflection without needing an external guide pillar.
Dual-Station Actuation
Powers a dual-station clamping fixture on automotive assembly equipment, using the second protruding rod end to trigger a mechanical flag.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD100X40SB the Right Cylinder?
Selecting this 100mm bore involves comparing thrust against neighboring sizes. An 80mm version provides 2267.8N at 0.5MPa, while a 125mm bore yields 5733.8N at the same pressure. This model outputs 3524.8N at 0.5MPa, striking a balance for heavy loads. If your application only requires unidirectional thrust, a single-rod ACQ cylinder offers a shorter footprint. If precise linear guidance without rotation is critical over a longer span, a guided TACQ module might fit better. Confirm the 40mm stroke, M26x1.5 male threads, and PT3/8 ports 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 ACQD100X40SB FAQ
Push and pull forces are equal at 3524.8N @0.5MPa and 4934.8N @0.7MPa, with a maximum capacity of 719kgf @1.0MPa. Because a rod occupies both chambers, the annular area is identical in each direction. The maximum standard stroke for a 100mm bore is 100mm.
No, a standard ACQD does not hold position upon air loss; the rod drifts and the fixed NBR bumpers only decelerate near the stroke ends. For fail-safe load holding, you must install an external rod lock or a pilot-operated check valve.
