Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X50-10
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X50-10 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 50mm 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 ACQJ40X50-10
The AirTAC ACQJ40X50-10 is a double-acting JIS compact cylinder with a 50mm full stroke and a 10mm external adjustment window. A threaded stop with a lock nut on the rod-end side lets you fine-tune the extend end position on the machine itself, yielding a usable extend range of 40-50mm. The retract stroke remains completely unaffected by this mechanism.
Because the piston area stays the same, output force is identical to a standard ACQ of this bore, delivering 628.3N of push at 0.5MPa. The unit features a 16mm piston rod, a PT1/8 port, and fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration. While this specific model ships without a magnet, the body retains sensor grooves for mounting reed or solid-state switches if needed later.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø40 mm |
| Full stroke | 50 mm |
| 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 (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 ACQJ40X50-10 Is Used
Machining Fixture Stops
Dial in the exact extend stop on a CNC machining fixture to accommodate raw material thickness variations without swapping out cylinder hardware.
Product Changeover Guides
Rapidly reposition the extend end point on packaging lines during format changeovers, using the external M12x1.25 adjuster to set new product widths.
Assembly Press Tuning
Test and set precise trial end positions on an assembly press, adjusting the 40-50mm stroke window on the fly to perfect pressing depth.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X50-10 the Right Cylinder?
When sizing this 40mm bore actuator, consider the neighbouring capacities: a 32mm bore provides 402.1N of push force, while a 50mm bore yields 981.8N at 0.5MPa. If your extend end position never varies, a fixed-stroke ACQ cylinder is simpler and suffices. To order this adjustable version correctly, confirm the 40mm bore, 50mm full stroke, 10mm window, female rod-end thread (M8x1.25), and whether you require the -S magnet option for switch 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 ACQJ40X50-10 FAQ
This 40mm bore cylinder provides 628.3N push and 527.8N pull at 0.5MPa, 879.6N push at 0.7MPa, and a maximum push of 128kgf at 1.0MPa. The full stroke is 50mm with a 10mm window, allowing an adjustable extend range of 40-50mm.
No, the external threaded stop alters only the extend stroke length, not the piston area, so force remains identical to a standard ACQ. The cylinder relies on fixed elastomer bumpers for deceleration and does not hold its load on air loss; for fail-safe holding, use an external rod lock.
