Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-30
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-30 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 35mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.

About the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-30
The AirTAC ACQJ32X35-30 is a double-acting JIS compact cylinder featuring a 32mm bore and a 35mm full stroke. An external threaded stop with a lock nut limits the extend end position, providing a usable extend range of 5-35mm. The retract stroke remains completely unaffected. Because the piston area is unchanged, the output force is identical to a standard ACQ of this bore, delivering 402.1N push force at 0.5MPa.
This unit features a 16mm piston rod, a female M8x1.25 rod-end thread, and PT1/8 ports. It includes fixed elastomer bumpers at both ends for end-of-stroke deceleration. While this specific model ships without a magnet, the body retains magnetic-switch grooves for adding position sensing if needed later.

| Rod thread | M8×1.25 (F) / M14×1.5 (B) |
Specifications follow the official AirTAC ACQJ datasheet. The adjustable stop shortens the EXTEND stroke only; the piston area — and therefore the force — is the same as a standard ACQ of this bore. Adjustable window options: 10/20/30/40/50/75/100 mm.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 302 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
Force equals a standard ACQ of the same bore — the adjuster changes stroke length, not piston area. Actual usable force is lower due to friction; size with a safety margin.

Where the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-30 Is Used
Multi-Product Machining Stops
Set precise extend positions for machining different part lengths on a single CNC fixture without fabricating custom spacers.
Assembly Line Changeover
Quickly alter the extend reach during automated assembly line product changeovers to accommodate varying component widths.
Packaging Flap Folding
Fine-tune the folding arm extension on packaging equipment to handle various carton sizes and prevent crushing.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-30 the Right Cylinder?
When sizing this 32mm bore actuator, consider the neighbouring options for your force requirements. Stepping down to a 25mm bore yields 245.4N push force at 0.5MPa, while stepping up to a 40mm bore provides 628.3N. If your extend end position never varies, a fixed-stroke ACQ cylinder is sufficient. For this adjustable variant, confirm the 32mm bore, 35mm full stroke, 30mm adjustment window, female rod thread, and that no magnet (-S) is required for your setup.
Quick checklist
- ✓ Need on-machine end-position tuning?
- ✓ Full stroke and adjust window (mm)
- ✓ Force at your working pressure
- ✓ 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 Lock the adjuster nut after setting the stop.
- check The stop limits the EXTEND stroke only.
- check Avoid side load on the short piston rod.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-30 FAQ
The usable extend range is 5-35mm (a 35mm full stroke shortened by up to a 30mm window). The retract stroke is unaffected. Force is identical to a standard ACQ: 402.1N push and 301.6N pull at 0.5MPa, 562.9N push at 0.7MPa, and a maximum push of 82kgf at 1.0MPa.
An external M12x1.25 threaded stop with a lock nut mechanically limits the extend distance, changing only the stroke length, not the force. The cylinder uses fixed NBR elastomer bumpers, not adjustable air cushions. Note that a plain ACQ does not hold its load on air loss; use an external rod lock for fail-safe holding.
