Airtac ACQD Double Acting Compact Cylinder ACQD50X5SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X5SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm bore and 5mm 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 ACQD50X5SB
The AirTAC ACQD50X5SB is a JIS compact double-acting cylinder featuring a 50mm bore and 5mm stroke. A 20mm piston rod extends from both ends, creating identical annular areas. This yields exactly 824.6N at 0.5MPa and 1154.5N at 0.7MPa of force in both directions, ensuring symmetric push and pull cycles. The male M18x1.5 rod-end threads couple directly to your load.
Twin rods drastically increase guide length and resist torsion without needing an external anti-rotation guide. The second rod end can drive a sensor flag or a secondary platform. Fixed NBR elastomer bumpers absorb impact at stroke extremes, and the integrated -S magnet supports reed or solid-state switches.
Airtac ACQD Double Acting Compact Cylinder ACQD50X5SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD50X5SB |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 5 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 ACQD50X5SB Is Used
Twin-Guided Part Pusher
Ideal for pushing machined components on an assembly line, using the dual rods to maintain precise alignment and prevent binding over short 5mm movements.
Symmetric Transfer Mechanism
Drives a transfer carriage in packaging machinery where identical push and pull forces ensure consistent acceleration and deceleration of products.
Dual-Station Actuation
Operates two separate workstations simultaneously from a single compact body, using the second protruding rod end to trigger a remote valve or flag.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X5SB the Right Cylinder?
At 0.5MPa this 50mm bore provides 824.6N equal force, sitting between the 63mm bore (1401.5N) and the 40mm bore (527.8N). Choose the 63mm for heavier thrust or the 40mm for a smaller footprint. This 5mm micro-stroke suits high-frequency clamping. If your application suffers air loss, note that a plain ACQ drifts; add an external pilot-operated check valve for fail-safe load holding. Confirm PT1/4 ports and the M18x1.5 male threads when ordering.
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 ACQD50X5SB FAQ
Because the double-rod design creates equal annular areas, push and pull forces are identical: 824.6N at 0.5MPa and 1154.5N at 0.7MPa. The maximum holding force is 168kgf at 1.0MPa. The standard stroke limit for this 50mm bore is 100mm, and this specific model has a 5mm stroke.
The -B option indicates male M18x1.5 piston rod threads on both ends for direct load coupling. Instead of adjustable air cushions, it uses fixed NBR elastomer bumpers at each end to absorb impact. For high kinetic energy loads, add an external shock absorber to protect the cylinder.
