Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X35-10
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X35-10 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm 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 ACQJ40X35-10
The AirTAC ACQJ40X35-10 is a double-acting JIS compact cylinder featuring a 40mm 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 25-35mm. The retract stroke remains completely unaffected by this adjustment. Because the piston area is unchanged, the output force is identical to a standard ACQ of this bore, delivering 628.3N push and 527.8N pull at 0.5MPa.
This model incorporates a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. It features a 16mm piston rod, a PT1/8 port, and a female M8x1.25 rod-end thread. The body includes magnetic-switch grooves for positioning sensors, though this specific unit ships without a magnet. Operating pressure spans 0.15-1.0MPa, with a speed range of 30-500mm/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 (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 ACQJ40X35-10 Is Used
Machining Fixture Clamping
Dial in the exact clamping extension on a CNC fixture during first-article inspection without machining custom spacers.
Packaging Line Changeover
Rapidly adjust the extend stop to accommodate different carton sizes on a packaging conveyor during product transitions.
Lab Press Positioning
Set precise trial end positions on a pneumatic lab press, tweaking the 25-35mm range to find the optimal compression point.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X35-10 the Right Cylinder?
When sizing this 40mm bore actuator, note that a 32mm bore provides 402.1N push at 0.5MPa, while a 50mm bore yields 981.8N. If your extend position never varies, a fixed-stroke ACQ cylinder is sufficient. To order this adjustable version correctly, confirm the 40mm bore, 35mm full stroke, 10mm adjustment window, female rod thread, and whether you need the -S magnet option for sensor feedback.
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 ACQJ40X35-10 FAQ
At 0.5MPa, the push force is 628.3N and the pull force is 527.8N. At 0.7MPa, the push is 879.6N, with a maximum push of 128kgf at 1.0MPa. The usable extend range is 25-35mm (the 35mm full stroke minus the 10mm adjustment window).
The external M12x1.25 threaded stop with a lock nut limits the extend length only; it does not alter the piston area, so force remains identical to a standard ACQ. Retract is unaffected. Deceleration is handled by a fixed elastomer bumper, 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.
