Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-40
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-40 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm 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 ACQJ40X60-40
The AirTAC ACQJ40X60-40 is a double-acting JIS compact cylinder featuring an external extend stop. A threaded adjuster with a lock nut lets you fine-tune the extend end position on the machine, yielding a usable extend range of 20 to 60 mm. The retract stroke remains fixed at the full 60 mm. Because the piston area is unaltered, the adjuster modifies stroke length only, keeping output force identical to a standard ACQ.
This 40 mm bore unit pushes with 628.3 N at 0.5 MPa and 879.6 N at 0.7 MPa. It uses a 16 mm rod, PT1/8 port, and an M12x1.25 adjuster thread. The body incorporates fixed elastomer bumpers at each end for deceleration and includes magnetic-switch grooves, though this specific configuration ships without a magnet. Operating pressure spans 0.15 to 1.0 MPa across a -20 to +70 C temperature range.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 ACQJ40X60-40 Is Used
Machining Fixture Clamping
Dial in the exact clamping reach on a CNC milling fixture during part-changeover, retracting the rod up to 40 mm to avoid swapping physical stop spacers.
Carton Sealing Tampers
Adjust the extend position on a packaging line tamper head to accommodate varying box heights, ensuring consistent flap folding without hardware changes.
Assembly Press Setup
Establish trial end positions for pressing bearings on an assembly line, tweaking the extend stroke within the 20-60 mm window until the optimal insertion depth is found.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-40 the Right Cylinder?
For lower force needs, the 32 mm bore delivers 402.1 N push at 0.5 MPa, while the larger 50 mm bore provides 981.8 N if your application requires more thrust. If your end position never varies, a fixed-stroke ACQ cylinder is sufficient. When ordering this adjustable model, verify the 40 mm bore, 60 mm full stroke, 40 mm window, female rod thread (M8x1.25), and whether you need the -S magnet option for sensing.
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 ACQJ40X60-40 FAQ
The usable extend range is 20 to 60 mm (a 40 mm window off the 60 mm full stroke). Force is identical to a standard ACQ: 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push at 0.7 MPa, and a maximum push of 128 kgf at 1.0 MPa.
An external M12x1.25 threaded stop with a lock nut limits the extend stroke without altering piston area, so force stays the same. The retract stroke is unaffected. Deceleration relies on fixed elastomer bumpers, not adjustable air cushions; for high-energy loads, use an external shock absorber.
