Airtac ACQD Double Acting Compact Cylinder ACQD50X35B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X35B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm bore and 35mm 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 ACQD50X35B
The AirTAC ACQD50X35B 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 perfectly equal push and pull forces of 824.6N at 0.5MPa and 1154.5N at 0.7MPa, enabling highly symmetric actuation cycles.
The dual rods resist rotation and provide a longer guide length, allowing you to carry a small tool platform without needing an external anti-rotation guide. This 50mm bore unit includes a male M18x1.5 rod-end thread for direct load coupling, PT1/4 ports, and fixed NBR elastomer bumpers at both ends. The body retains magnetic-switch grooves, though this specific variant ships without a magnet.
Airtac ACQD Double Acting Compact Cylinder ACQD50X35B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD50X35B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 35 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 ACQD50X35B Is Used
Symmetric Transfer Pusher
Drives a dual-sided conveyor transfer station in packaging lines, utilizing the equal bidirectional 824.6N force to push and retract parts smoothly.
Twin-Guided Stamping Platform
Carries a small stamping head on a CNC router without an external guide, relying on the twin rods to prevent torsion during the 35mm work stroke.
Dual-Station Machine Actuation
Powers a dual-station clamping fixture on an automated assembly machine, using the second protruding rod end to drive a secondary flag or load.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X35B the Right Cylinder?
When sizing this 50mm bore, note the adjacent options: the 40mm bore yields 527.8N and the 63mm bore yields 1401.5N at 0.5MPa. If your application only requires unidirectional thrust where push significantly exceeds pull, a single-rod ACQ cylinder might suffice. For heavier lateral loads needing a fully integrated non-rotating guide, a TACQ guided rail cylinder offers superior support. To order, confirm the 35mm stroke, the male M18x1.5 rod thread (-B), and the PT1/4 port size.
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 ACQD50X35B FAQ
This double-acting cylinder provides an equal push and pull force of 824.6N at 0.5MPa and 1154.5N at 0.7MPa, with a maximum load capacity of 168kgf at 1.0MPa. Push and pull forces are identical because the rod occupies both chambers, creating the same annular area in each direction. The maximum standard stroke available for this 50mm bore is 100mm.
It uses fixed NBR elastomer bumpers at both ends to absorb impact, which are not adjustable. For high-speed or high-energy cycles, add an external shock absorber. A plain ACQD does not hold its load when air is lost; for fail-safe positioning, install an external rod lock or pilot-operated check valve.
