Airtac ACQD Double Acting Compact Cylinder ACQD100X40B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD100X40B 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 ACQD100X40B
The AirTAC ACQD100X40B is a double-acting JIS compact cylinder featuring twin rods extending from both ends. Because a rod occupies each chamber, the annular area remains identical in both directions, yielding equal push and pull forces of 3524.8N at 0.5MPa and 4934.8N at 0.7MPa. This symmetry is ideal for applications requiring balanced bi-directional cycles.
The dual-rod architecture resists rotation and extends guide length, allowing a 100mm bore platform to carry offset loads without an external guide. It features a fixed NBR bumper for end-of-stroke deceleration, PT3/8 ports, and a male M26x1.5 rod-end thread for direct mounting. Note that this unit ships without a magnet and does not hold position on air loss.
Airtac ACQD Double Acting Compact Cylinder ACQD100X40B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD100X40B |
|---|---|
| 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 ACQD100X40B Is Used
Twin-Guided Pusher
Drives a heavy machining fixture pusher with equal force both ways, using the dual rods to prevent deflection during high-tonnage clamping.
Symmetric Transfer Unit
Shifts a large automotive sub-assembly between stations, relying on the matching push and pull forces to maintain smooth transfer dynamics.
Dual-Station Actuation
Powers a dual-station press feed where the second rod end mounts a sensor flag to track the 40mm stroke position without external guides.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD100X40B the Right Cylinder?
For 0.5MPa operations requiring 3524.8N both ways, this 100mm bore matches perfectly. If lower force is acceptable, the 80mm bore provides 2267.8N, while larger custom frames are needed for higher output. Choose this double-rod ACQD over a single-rod ACQ when equal push/pull or anti-rotation is mandatory. Add an external rod lock if fail-safe load holding is required. Confirm the 40mm stroke, PT3/8 port, and male M26x1.5 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 ACQD Double Acting Compact Cylinder ACQD100X40B FAQ
This double-acting cylinder provides equal push and pull forces of 3524.8N at 0.5MPa and 4934.8N at 0.7MPa, with a maximum capacity of 719kgf at 1.0MPa. Push and pull are equal because the twin rods create the same annular area in both chambers. The standard stroke max is 100mm, the port is PT3/8, and the male rod-end thread is M26x1.5.
The twin rods resist rotation and provide extended guide length. It uses fixed NBR bumpers at both ends for deceleration, not adjustable air cushions. The body has grooves for reed or solid-state switches, but this specific model ships without a magnet. It does not hold position on air loss; an external rod lock or pilot check valve is required for fail-safe holding.
