Airtac ACQD Double Acting Compact Cylinder ACQD80X125B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD80X125B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø80mm bore and 125mm 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 ACQD80X125B
The AirTAC ACQD80X125B is a double-acting JIS compact cylinder featuring a piston rod protruding from both ends. Because a rod occupies each chamber, the annular area remains identical in both directions, generating equal push and pull forces of 2267.8N at 0.5MPa and 3175N at 0.7MPa. This symmetry is ideal for applications requiring consistent bi-directional thrust without force imbalance.
This 80mm bore variant utilizes a 125mm stroke, exceeding the 100mm standard maximum to function as a made-to-order long-stroke unit. The twin rods resist rotation and provide an extended guide length, eliminating the need for a separate external guide. It features a male M22x1.5 rod-end thread for direct coupling, a PT3/8 port, and fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration.
Airtac ACQD Double Acting Compact Cylinder ACQD80X125B Technical Specifications

|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 125 mm |
| Acting type | Double acting, double rod |
| Port size | PT3/8 |
| Rod end thread | M16×2.0 female / M22×1.5 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 (Ø80mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | 3175 N |
| Max (@1.0 MPa) | 463 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 ACQD80X125B Is Used
Symmetric Transfer Pusher
Drives a packaging line pusher that advances and retracts with identical 3175N force, ensuring smooth product transfer without speed discrepancies between cycles.
Dual-Station Actuation
Uses both rod ends on an electronics assembly machine to actuate two separate test fixtures simultaneously, maintaining precise parallel movement.
Twin-Guided Lift Platform
Raises and lowers a small tooling platform in a CNC machining cell; the twin rods prevent rotational drift without needing bulky external linear bearings.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD80X125B the Right Cylinder?
Selecting this 80mm bore unit involves comparing adjacent sizes: the 63mm bore yields 1401.5N at 0.5MPa, while the 100mm bore provides 3524.8N. This model outputs 2267.8N at 0.5MPa, fitting medium-heavy load requirements perfectly. If your mechanism only requires force in one direction, a single-rod ACQ cylinder offers a shorter overall length. If high lateral loads are present alongside the need for anti-rotation, a guided TACQ series might be preferable. Confirm ordering essentials: this configuration includes the -B male M22x1.5 thread and lacks the -S magnet, though sensor grooves remain machined into the body.
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 ACQD80X125B FAQ
The push and pull forces are equal at 2267.8N at 0.5MPa and 3175N at 0.7MPa, with a maximum of 463kgf at 1.0MPa. Equality occurs because the double-rod design creates the same annular area in both chambers. The 125mm stroke is a made-to-order long-stroke variant, exceeding the 100mm standard maximum for this 80mm bore.
It uses fixed NBR elastomer bumpers at both ends for impact absorption rather than adjustable air cushions. A plain ACQ-type cylinder does not hold its load if air pressure is lost; the rod will drift. For fail-safe load holding, an external rod lock or pilot-operated check valve must be installed separately.
