The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD32X15SG is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø32mm bore and 15mm 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 ACQD32X15SG is a JIS compact double-acting cylinder where a Ø16mm piston rod protrudes from both ends. Because a rod occupies each chamber, the effective annular area is identical in both directions, yielding perfectly equal push and pull forces of 301.6N at 0.5MPa and 422.2N at 0.7MPa. The twin-rod architecture inherently resists rotation and provides an extended guide length, allowing you to mount a tool platform directly without needing an external anti-rotation guide.
This 32mm bore model features a 15mm stroke and a PT1/8 port. It uses a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. The -SG variant includes a built-in piston magnet for position sensing alongside a male M14x1.5 rod-end thread, while the opposite rod end can drive a secondary load or sensor flag.

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 precision machining fixture pusher where the dual rods prevent platform twisting during the 15mm clamping cycle.
Powers a packaging line transfer gate with equal force both ways, ensuring consistent timing regardless of travel direction.
Actuates a dual-station electronics testing jig, using the second rod end to trigger a solid-state sensor flag simultaneously.
Selecting this 32mm bore provides 301.6N of force at 0.5MPa. If your application requires less force, stepping down to a 25mm bore yields 188.9N, while moving up to a 40mm bore provides 527.8N. A single-rod ACQ cylinder is preferable if you only need standard unidirectional pushing and want maximum forward thrust, whereas a guided TACQ linear slide is ideal for heavy off-axis loads. Remember that a plain ACQD does not hold position upon air loss; you must add an external rod lock or pilot check valve for fail-safe load holding. Confirm the 15mm stroke, magnet, and male thread options when ordering.
Quick checklist
The push and pull forces are equal at 301.6N @0.5MPa and 422.2N @0.7MPa, with a maximum force of 61kgf @1.0MPa. Force is identical both ways because the double-rod design creates the same annular area in each chamber. The maximum standard stroke available for this 32mm bore is 100mm.
The twin rods resist rotation and extend guide length so no external guide is needed. It uses fixed NBR elastomer bumpers at both ends for deceleration, not adjustable air cushions. The built-in magnet (-S) works with reed or electronic solid-state switches, and the second rod end can drive a secondary load.
