Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X60-40
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X60-40 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 60mm 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 ACQJ32X60-40
The AirTAC ACQJ32X60-40 is a double-acting JIS compact cylinder featuring a 32mm bore and a 60mm full stroke. An external M12x1.25 threaded stop with a lock nut limits the extend end position, providing a usable extend range of 20 to 60mm. This allows operators to fine-tune the forward stroke directly on the machine without swapping components. The retract stroke remains completely unaffected.
Because the adjuster only restricts travel length and leaves piston area unchanged, output force is identical to a standard ACQ of this bore. The 16mm rod delivers 402.1N push and 301.6N pull force at 0.5 MPa. The riveted body includes fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration, and the structure features sensor grooves ready for magnetic switches.

| Adjuster thread | M12×1.25 |
| Port size | PT1/8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| Speed range | 30 – 500 mm/s |
| 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 ACQJ32X60-40 Is Used
Machining Fixture Tuning
Dial in the exact clamping reach on a CNC fixture during initial setup, allowing 20 to 60mm of forward travel to accommodate varying raw material thicknesses without changing cylinders.
Packaging Changeover Stops
Rapidly adjust the extend end position for product format changes on a packaging line, using the external lock nut to set new pusher limits quickly between production runs.
Assembly Press Trials
Safely test and establish the final pressing depth on an automated assembly press, tweaking the stroke window incrementally to find the optimal end position before locking the nut.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X60-40 the Right Cylinder?
When sizing this 32mm bore, stepping down to a 25mm bore drops the 0.5 MPa push force to 245.4N, while moving up to a 40mm bore raises it to 628.3N. If your application requires a fixed 60mm extend position every cycle without any tuning, a standard ACQ32X60 cylinder is sufficient. To order this adjustable version correctly, confirm the 32mm bore, 60mm full stroke, 40mm window, female M8x1.25 rod thread, and note this specific model ships without a magnet.
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 ACQJ32X60-40 FAQ
The 32mm bore generates 402.1N push and 301.6N pull at 0.5 MPa, and 562.9N push at 0.7 MPa, with a maximum push of 82 kgf at 1.0 MPa. The full stroke is 60mm with a 40mm window, yielding a usable extend range of 20-60mm. It uses a PT1/8 port, a 16mm rod, an M8x1.25 female rod-end thread, and an M12x1.25 external adjuster thread.
No, the adjuster changes stroke length only, so force remains identical to a standard ACQ. The cylinder relies on fixed elastomer bumpers for deceleration, not adjustable air cushions. Note that this model ships without a sensor magnet, and a plain compact cylinder will not hold a load if air pressure is lost; use an external rod lock for fail-safe holding.
