Airtac ACQD Double Acting Compact Cylinder ACQD50X70SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X70SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm 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 ACQD50X70SB
The AirTAC ACQD50X70SB is a double-acting JIS compact cylinder featuring twin rods extending from both ends. Because a rod occupies each chamber, the annular area is identical in both directions, yielding equal push and pull forces of 824.6N at 0.5MPa and 1154.5N at 0.7MPa. This bore uses a PT1/4 port, a Ø20mm piston rod, and a male M18x1.5 rod-end thread for direct load coupling.
The dual-rod architecture inherently resists rotation and provides an extended guide length, eliminating the need for a separate external anti-rotation guide in many setups. 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. The -S magnet enables position detection with reed or solid-state switches, and the maximum standard stroke for this 50mm bore is 100mm.
Airtac ACQD Double Acting Compact Cylinder ACQD50X70SB Technical Specifications

| Bore size | Ø50 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 (Ø50mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 825 N | 825 N |
| 0.7 MPa | 1155 N | 1155 N |
| Max (@1.0 MPa) | 168 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 ACQD50X70SB Is Used
Symmetric Transfer Unit
Drives a dual-sided pick-and-place head in electronics assembly, using the equal push/pull force to maintain balanced positioning during component transfer.
Twin-Guided Pusher
Pushes parts into a CNC machining station. The twin rods resist torsional loads without needing an external guide, while the male M18x1.5 thread directly mounts the tool.
Dual-Station Actuation
Actuates two clamps simultaneously on an automotive fixture. One rod drives the primary clamp while the opposite rod operates a secondary mechanism.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X70SB the Right Cylinder?
This 50mm bore generates 824.6N of force both ways at 0.5MPa. Stepping down to a 40mm bore yields 527.8N, while stepping up to a 63mm bore provides 1401.5N, allowing precise sizing for symmetric push/pull cycles. If your application only requires force in one direction, a single-rod ACQ cylinder is more compact. For applications demanding high lateral load capacity, a guided TACQ cylinder might be a better fit. To order, confirm the 70mm stroke, PT1/4 port, male M18x1.5 rod thread, and the integrated magnet for switches.
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 ACQD50X70SB FAQ
It delivers an equal push and pull force of 824.6N at 0.5MPa and 1154.5N at 0.7MPa, with a maximum holding force of 168kgf at 1.0MPa. The push and pull forces are identical because the double-rod design creates the same annular area in both directions. The maximum standard stroke available for this 50mm bore is 100mm.
It uses fixed NBR elastomer bumpers at both ends for impact absorption, not adjustable air cushions. For high-speed or high-energy loads, an external shock absorber is recommended. A plain ACQD does not hold position when air is lost; for fail-safe load holding, an external rod lock or pilot-operated check valve is required.
