Airtac ACQD Double Acting Compact Cylinder ACQD50X70
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X70 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 ACQD50X70
The AirTAC ACQD50X70 is a double-acting JIS compact cylinder featuring a twin-rod design where a piston extends from both body ends. Because a rod occupies each internal chamber, the effective annular area remains identical in both directions. This yields perfectly equal push and pull forces of 824.6N at 0.5MPa and 1154.5N at 0.7MPa, enabling highly symmetric cycle movements without differential thrust.
The dual rods inherently resist rotation and provide an extended guide length, allowing the unit to support a small tool platform directly without requiring an external anti-rotation guide. The second rod end can drive a sensor flag or a secondary load. This 50mm bore variant features a 20mm piston rod, a PT1/4 port, and fixed NBR elastomer bumpers at both ends to absorb end-of-stroke impact. Please note this specific configuration ships without a magnet, though the body retains integrated switch grooves.
Airtac ACQD Double Acting Compact Cylinder ACQD50X70 Technical Specifications

| Series | ACQD JIS compact double-rod cylinder |
| 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 ACQD50X70 Is Used
Symmetric Transfer Pusher
Drives a dual-sided product diverter on packaging lines where equal 824.6N push and pull forces ensure consistent timing in both directions without momentum drift.
Twin-Guided Stamping Platform
Carries a small marking head on an electronics assembly machine, using the extended guide length of both rods to resist torsional deflection during the stamping contact.
Dual-Station Actuation
Powers a secondary reject arm on a logistics conveyor via the second rod end, actuating a sensor flag while the primary side pushes misaligned parcels off the belt.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X70 the Right Cylinder?
When sizing this 50mm bore actuator, consider the adjacent options for your thrust requirements. Stepping down to a 40mm bore provides 527.8N at 0.5MPa, while stepping up to a 63mm bore yields 1401.5N at 0.5MPa. If your application needs a single protruding rod or allows for greater push than pull force, the standard single-rod ACQ series is a more compact choice. If heavy lateral loads exceed the twin rods' guide capacity, a guided TACQ cylinder provides enhanced load bearing. To order, confirm the 70mm stroke, the default female M10x1.5 rod-end thread, and the PT1/4 port.
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 ACQD50X70 FAQ
The ACQD50X70 operates at 0.15-1.0MPa and delivers an equal push and pull force of 824.6N at 0.5MPa and 1154.5N at 0.7MPa. Push and pull forces are identical because the twin rods create the same annular piston area in both chambers. The maximum standard stroke for this 50mm bore is 100mm, and it can generate a maximum force of 168kgf at 1.0MPa.
The twin rods exiting both ends prevent rotation and add guide length without needing an external guide. This specific model lacks a -S magnet, but the body still has grooves for mounting reed or solid-state switches. Fixed NBR elastomer bumpers at both ends absorb end-of-stroke impact; this is not an adjustable air cushion, so external shock absorbers may be needed for high-energy loads.
