The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD32X35SB is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø32mm 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.
The AirTAC ACQD32X35SB is a double-acting JIS compact cylinder featuring a 16mm rod exiting both ends. Because both chambers are annular, it generates identical push and pull forces of 301.6N at 0.5MPa and 422.2N at 0.7MPa. This symmetry is ideal for applications requiring balanced bi-directional thrust without pressure compensation.
The twin-rod architecture inherently resists rotation and extends the guide length, eliminating the space and cost of an external guide rail. A fixed NBR bumper absorbs impact at each end, while the -S magnet enables position detection using reed or solid-state switches. The -B male M14x1.5 thread couples directly to tooling, and the PT1/8 port manages airflow for the 35mm stroke.

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.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 302 N | 302 N |
| 0.7 MPa | 422 N | 422 N |
| Max (@1.0 MPa) | 62 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.

Thread: PT standard (G / NPT available). The twin rods resist rotation and add guiding length. Related: ACQ (single rod), ACQJ (adjustable stroke), TACQ (guided).
Drives a dual-sided transfer arm on packaging machinery, utilizing the equal push and pull forces to maintain stable motion profiles during product handoff.
Handles electronic components on an SMT line, where the second rod end mounts a sensor flag while the twin rods prevent jaw rotation without external guides.
Powers a clamping fixture on a CNC machining center, using the male M14x1.5 thread to secure a workholding tool while the opposing rod drives a secondary ejector.
At 0.5MPa, this 32mm bore yields 301.6N of equal bidirectional force. If your load requires less thrust, the 25mm variant provides 188.9N; for heavier demands, step up to the 40mm bore delivering 527.8N. Choose a single-rod ACQ if anti-rotation is unnecessary, or a guided TACQ for high lateral loads. This configuration includes the -S magnet and -B male M14x1.5 rod end.
Quick checklist
It delivers equal push and pull forces of 301.6N at 0.5MPa and 422.2N at 0.7MPa, with a maximum capacity of 61kgf at 1.0MPa. Push and pull forces are identical because the double-rod design creates annular areas on both sides. The standard stroke limit is 100mm, the port is PT1/8, and the male rod-end thread is M14x1.5.
No, a plain ACQD does not hold position on air loss; the rod drifts and requires an external rod lock or pilot-operated check valve for fail-safe holding. For motion control, it uses fixed NBR elastomer bumpers at both ends rather than adjustable air cushions, so external shock absorbers are recommended for high-energy loads.
