Airtac ACQD Double Acting Compact Cylinder ACQD100X20B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD100X20B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø100mm bore and 20mm 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 ACQD100X20B
The AirTAC ACQD100X20B is a double-acting JIS compact cylinder featuring a 100mm bore and a 20mm stroke. A 32mm piston rod protrudes from both ends, providing an identical annular working area in each chamber. This symmetry generates an equal push and pull force of 3524.8N at 0.5MPa and 4934.8N at 0.7MPa, enabling perfectly balanced bidirectional motion. The male M26x1.5 rod-end threads couple directly to your tooling.
Twin rods grant a longer guide length and inherent torsional resistance, eliminating the need for an external anti-rotation guide for small platforms. The second rod end can drive a sensor flag or a secondary load. Deceleration is handled by fixed NBR elastomer bumpers at both ends rather than adjustable air cushions. Please note this unit ships without a magnet, though body grooves remain available for mounting switches.
Airtac ACQD Double Acting Compact Cylinder ACQD100X20B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD100X20B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 20 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 ACQD100X20B Is Used
Twin-Guided Pusher
Drives a wide format press plate in an automotive stamping cell, relying on the dual rods to resist torsional deflection during high-force metal forming.
Symmetric Transfer
Powers a centering jaw on a heavy-duty packaging conveyor, using the identical push and pull forces to secure large palletized goods without skewing.
Dual-Station Actuation
Actuates opposing clamp arms simultaneously on a multi-spindle machining center, using the second protruding rod end to drive an external mechanical flag.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD100X20B the Right Cylinder?
Selecting this 100mm bore yields 719kgf maximum thrust at 1.0MPa. If your application requires less energy, the 80mm bore provides 2267.8N at 0.5MPa. For heavier demands, the 125mm bore offers 5733.8N at 0.5MPa. This specific 20mm stroke suits short clamping or ejection tasks within the 100mm standard maximum. A standard single-rod ACQ is preferable if equal bidirectional force is unnecessary, while a guided TACQ fits loads exceeding the torsional limits of the twin rods. Confirm your PT3/8 port connections and M26x1.5 male rod threading 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 ACQD100X20B FAQ
It delivers an equal push and pull force of 3524.8N at 0.5MPa and 4934.8N at 0.7MPa, with a maximum capacity of 719kgf at 1.0MPa. Push and pull forces are identical because the double-rod design creates the same annular piston area in both directions. The maximum standard stroke available for this 100mm bore is 100mm.
No, a plain ACQD does not hold its load when air is removed or the valve is centered; the rod will drift. The fixed NBR elastomer bumpers only decelerate the piston near the stroke ends and do not function as a brake. For fail-safe load holding, you must install an external rod lock or a pilot-operated check valve.
