Airtac ACQD Double Acting Compact Cylinder ACQD16X20SB
The AirTAC ACQD Double Acting Compact Cylinder ACQD16X20SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø16mm bore and 20mm 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 ACQD16X20SB
The AirTAC ACQD16X20SB is a double-acting JIS compact cylinder featuring twin rods that exit from both body ends. Because a rod occupies each internal chamber, the effective annular area is identical in both directions, yielding perfectly equal push and pull forces of 75.4N at 0.5 MPa and 105.6N at 0.7 MPa. This symmetry is ideal for symmetric transfer cycles, while the parallel rods inherently resist rotation and extend guide length without needing a separate external guide.
Equipped with a male M6x1.0 rod-end thread, it couples directly to tooling platforms. The fixed TPU elastomer bumper at each end decelerates the motion near stroke extremes, replacing complex adjustable air cushions. An M5x0.8 port manages airflow, and the included -S magnet enables position sensing across both reed and electronic solid-state switches installed along the body grooves.
Airtac ACQD Double Acting Compact Cylinder ACQD16X20SB Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD16X20SB |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø16 mm |
| Stroke | 20 mm |
| Acting type | Double acting, double rod |
| Port size | M5×0.8 |
| Rod end thread | M4×0.7 female / M6×1.0 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 60 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 (Ø16mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 75 N | 75 N |
| 0.7 MPa | 106 N | 106 N |
| Max (@1.0 MPa) | 15 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 ACQD16X20SB Is Used
Symmetric Transfer Arms
Drives pick-and-place arms in electronics assembly where equal push and pull forces prevent uneven wear on delicate component grippers.
Twin-Guided Pusher
Moves small product cartons on packaging lines; the dual rods maintain parallel alignment without binding, eliminating external guide rails.
Dual-Station Actuation
Operates a secondary sensor flag or clamp from the opposite rod end on semi-automated test fixtures, synchronizing two actions in one stroke.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD16X20SB the Right Cylinder?
Providing 75.4N of thrust both ways, this 16mm bore unit bridges the gap between the smaller 12mm (42.4N) and larger 20mm (117.8N) variants. If your application only requires unidirectional push force and space is extremely tight, a single-rod ACQ cylinder might suffice. However, for dual-station actuation or carrying a small tool platform without rotational play, this double-rod configuration is superior. Confirm your ordering code includes the S (magnet) and B (male M6x1.0 thread) options, and note the 20mm stroke sits well within the 60mm maximum standard limit.
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 ACQD16X20SB FAQ
The cylinder generates 75.4N of force at 0.5 MPa and 105.6N at 0.7 MPa, with a maximum capacity of 15kgf at 1.0 MPa. Because it is a double-rod design, the push and pull forces are exactly equal due to the identical annular area on both sides. The stroke is 20mm, and the maximum standard stroke available for this 16mm bore is 60mm.
It uses a fixed TPU elastomer bumper at each end to absorb impact, which is not an adjustable air cushion. A plain ACQD does not hold its position if air pressure is lost; the rod will drift. For fail-safe load holding, you must integrate an external rod lock or pilot-operated check valve.
