Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X40-30
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X40-30 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 40mm 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 ACQJ32X40-30
The AirTAC ACQJ32X40-30 is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. You get a usable extend range of 10-40 mm, set by subtracting the 30 mm window from the 40 mm full stroke. The retract stroke remains unaffected. Because the piston area is unchanged, force is identical to a standard ACQ of this bore, delivering 402.1 N push and 301.6 N pull at 0.5 MPa.
This 32 mm bore unit uses a PT1/8 port and a 16 mm rod with a female M8x1.25 rod-end thread. The external adjuster carries an M12x1.25 thread for precise positioning. It includes fixed elastomer bumpers at both ends rather than adjustable air cushions. While this specific model ships without a magnet, the body retains standard switch grooves for adding sensors later. Operating pressure spans 0.15-1.0 MPa with speeds of 30-500 mm/s.

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 ACQJ32X40-30 Is Used
Machining Fixture Clamps
Dial in the exact clamping reach on a CNC machining fixture during product-changeover stops without machining new spacer plates.
Carton Sealing Heads
Adjust the extend end position on a packaging line to accommodate varying box heights, ensuring precise flap folding.
Assembly Press Stops
Fine-tune the pressing depth on an automated assembly press during trial runs to prevent part damage.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X40-30 the Right Cylinder?
For sizing, stepping down to a 25 mm bore yields 245.4 N push, while moving up to a 40 mm bore provides 628.3 N push at 0.5 MPa. Choose this 32 mm option when your application needs approximately 402.1 N of push force and on-machine extend tuning. If your end position never varies, a fixed-stroke ACQ cylinder is sufficient. When ordering, verify the 32 mm bore, 40 mm full stroke, 30 mm window, female rod thread, and whether you need the -S magnet option for sensor integration.
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 ACQJ32X40-30 FAQ
The force is identical to a standard ACQ: 402.1 N push and 301.6 N pull at 0.5 MPa, 562.9 N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The 40 mm full stroke has a 30 mm adjustable window, giving a usable extend range of 10-40 mm. The operating pressure is 0.15-1.0 MPa.
An external M12x1.25 threaded stop with a lock nut limits the extend distance without changing the piston area, so force remains unchanged. The retract stroke is unaffected. Deceleration relies on fixed elastomer bumpers at both ends, not an adjustable air cushion. Note that a plain cylinder does not hold its load on air loss; use an external rod lock for fail-safe holding.
