Airtac ACQD Double Acting Compact Cylinder ACQD63X70SBH
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X70SBH is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø63mm bore and 70mm 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 ACQD63X70SBH
The AirTAC ACQD63X70SBH is a double-acting JIS compact cylinder featuring twin rods that exit both ends. Because a piston rod occupies each chamber, the effective annular area remains identical in both directions. This yields equal push and pull force of 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa, ensuring symmetric thrust for advancing and retracting cycles.
The dual-rod architecture inherently resists rotation and provides an extended guide length, allowing it to carry a tool platform without needing an external anti-rotation guide. This 63mm bore unit includes a male M18x1.5 rod-end thread for direct load coupling, a PT1/4 port, and a built-in magnet for reed or solid-state sensing. Fixed NBR bumpers at both ends absorb end-of-stroke impact, while the second rod end can drive a sensor flag or secondary load.
Airtac ACQD Double Acting Compact Cylinder ACQD63X70SBH Technical Specifications

|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 70 mm |
| Acting type | Double acting, double rod |
| Port size | PT1/4 |
| Rod end thread | M10×1.5 female / M18×1.5 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 (Ø63mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | 1962 N |
| Max (@1.0 MPa) | 286 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 ACQD63X70SBH Is Used
Symmetric Transfer Arms
Drives dual-station pick-and-place arms in packaging machinery where equal advancing and retracting thrust prevents sagging during high-speed product transfer.
Twin-Guided Pushers
Pushes heavy pallets on conveyor lines without twisting, utilizing the inherent anti-rotation properties of the dual rods to maintain straight tracking.
Dual-End Actuation
Actuates a CNC fixture clamp from one end while mounting a position sensor flag on the opposite rod end for closed-loop machine feedback.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X70SBH the Right Cylinder?
At 0.5 MPa, this 63mm bore generates 1401.5 N of thrust both ways. For lighter duties, the 50mm bore provides 824.6 N, whereas stepping up to the 80mm bore yields 2267.8 N. If your application only requires unidirectional push force and lacks lateral loads, a single-rod ACQ cylinder might suffice. If your stroke length demands extreme rigidity beyond the 100mm standard maximum, a guided TACQ provides superior support. To order, confirm the 70mm stroke, the male M18x1.5 thread, the magnet option, and the PT1/4 porting.
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 ACQD63X70SBH FAQ
It delivers equal push and pull force of 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa, with a maximum capacity of 286 kgf at 1.0 MPa. Push and pull forces are identical because the twin rods create equal annular areas on both sides of the piston. The standard stroke limit is 100mm, and it features a male M18x1.5 rod thread.
No, a plain ACQD does not hold position upon air loss; the rod drifts and the fixed NBR bumpers only decelerate near stroke ends. For fail-safe load holding, you must add an external rod lock or a pilot-operated check valve. The twin rods provide anti-rotation guidance but do not brake the load.
