Airtac ACQD Double Acting Compact Cylinder ACQD16X40SB
The AirTAC ACQD Double Acting Compact Cylinder ACQD16X40SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø16mm bore and 40mm 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 ACQD16X40SB
The AirTAC ACQD16X40SB is a double-acting JIS compact cylinder featuring twin 8mm rods exiting both ends. Because a rod occupies each chamber, the annular area is identical in both directions, yielding equal push and pull forces of 75.4N at 0.5MPa and 105.6N at 0.7MPa. This symmetry is ideal for applications requiring consistent force in both motion directions.
The dual-rod architecture inherently resists rotation and provides an extended guide length, allowing a tool platform to be carried directly without needing a separate external guide. This SB configuration includes a built-in piston magnet for electronic or reed switches, and features male M6x1.0 rod-end threads for direct load coupling. It uses fixed TPU elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions, and operates reliably within a 0.15-1.0MPa pressure range at speeds of 30-500mm/s.
Airtac ACQD Double Acting Compact Cylinder ACQD16X40SB Technical Specifications

|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø16 mm |
| Stroke | 40 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 ACQD16X40SB Is Used
Symmetric Transfer Arms
Drives pick-and-place arms in electronics assembly where identical push and pull forces ensure balanced acceleration of delicate components across dual stations.
Twin-Guided Pusher
Pushes small parts down a packaging line conveyor without rotating the load, utilizing the extended guide length of the dual rods to prevent jaw binding.
Dual-Station Actuation
Actuates a secondary mechanism or sensor flag from the opposite rod end on a textile machine, synchronizing two processes with one compact cylinder.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD16X40SB the Right Cylinder?
For sizing context, the adjacent smaller ACQD12 bore provides 42.4N at 0.5MPa, while the larger ACQD20 bore yields 117.8N. If your mechanism only requires one-sided actuation and higher extension force, a single-rod ACQ cylinder may be a better fit. For loads demanding high lateral precision without a separate guide, the ACQD twin-rod design is optimal. When ordering this SB variant, confirm your need for the male M6x1.0 rod threads, the M5x0.8 port, and the magnet for switch mounting. The standard stroke limit for this 16mm bore is 60mm, making this 40mm unit a standard choice. Remember that a standard ACQ-type cylinder does not hold its load on air loss; if fail-safe holding is required, specify an external rod lock or pilot-operated check valve.
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 ACQD16X40SB FAQ
Because the double-rod design creates equal annular areas on both sides, push and pull forces are identical at 75.4N (0.5MPa) and 105.6N (0.7MPa), with a maximum of 15kgf at 1.0MPa. The maximum standard stroke available for this 16mm bore is 60mm.
It uses fixed TPU elastomer bumpers at both ends to decelerate the piston, meaning there are no adjustable air cushions; for high-energy impacts, add external shock absorbers. The included -S magnet works with both reed and solid-state electronic switches fitted into the body grooves.
