Airtac ACQD Double Acting Compact Cylinder ACQD50X45SB
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD50X45SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø50mm bore and 45mm 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 ACQD50X45SB
The AirTAC ACQD50X45SB is a double-acting JIS compact cylinder featuring twin rods that exit both ends. Because a rod occupies each chamber, the annular area is identical in both directions, giving exactly 824.6 N of force at 0.5 MPa and 1154.5 N at 0.7 MPa for both extension and retraction. The symmetrical layout prevents differential push-pull forces, ensuring perfectly balanced cycling on your tooling platform.
Twin Ø20 mm rods resist rotation naturally and add guide length, removing the need for a separate external anti-rotation guide. The -S magnet enables tracking via reed or solid-state electronic switches, while the -B male M18x1.5 thread couples directly to your load. Deceleration relies on fixed NBR elastomer bumpers at the stroke ends rather than adjustable air cushions.
Airtac ACQD Double Acting Compact Cylinder ACQD50X45SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD50X45SB |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 45 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 ACQD50X45SB Is Used
Symmetric Transfer Unit
Drives a dual-sided packaging transfer carriage where matching extension and retraction speeds prevent part skewing during transit.
Twin-Guided Pusher
Pushes metal stampings on a press line; the dual rods absorb lateral moment loads without twisting, eliminating an external guide rail.
Dual-Station Actuation
Simultaneously positions two workholding fixtures on a CNC machining center using the second rod end to drive a secondary mechanism.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD50X45SB the Right Cylinder?
At 0.5 MPa this 50 mm bore generates 824.6 N both ways; stepping up to the 63 mm bore yields 1401.5 N, while dropping to a 40 mm bore provides 527.8 N. If your application does not require equal push-pull forces or anti-rotation, a single-rod ACQ cylinder offers a lighter footprint. For heavy lateral loads exceeding the twin rods' guide capacity, a TACQ slide unit is recommended. Specify PT1/4 ports, the 45 mm stroke, and confirm the male M18x1.5 rod-end threading 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 ACQD50X45SB FAQ
It provides equal push and pull forces of 824.6 N at 0.5 MPa and 1154.5 N at 0.7 MPa, with a maximum holding capacity of 168 kgf at 1.0 MPa. Push and pull are equal because the double-rod design creates identical annular areas on both sides of the piston. The maximum standard stroke available for this 50 mm bore is 100 mm.
No, a plain ACQD does not hold position on air loss; the rod drifts and requires an external rod lock or pilot check valve for fail-safe holding. End-of-stroke deceleration comes from fixed NBR elastomer bumpers, not adjustable air cushions. For high kinetic energy loads, add an external shock absorber or slow the approach speed.
