Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X30-10
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X30-10 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 30mm 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 ACQJ40X30-10
The AirTAC ACQJ40X30-10 is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut to fine-tune the extend end position. You can shorten the outward stroke by up to 10mm, yielding a usable extend range of 20 to 30mm without swapping parts. The retract distance remains completely unaffected.
Because the piston dimensions stay constant, output force equals a standard ACQ of the same bore, delivering 628.3N push and 527.8N pull at 0.5MPa. The unit relies on a fixed elastomer bumper for end-of-stroke deceleration and includes sensor grooves. This specific SKU ships without a magnet, so you must add the -S option if position detection is required.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø40 mm |
| Full stroke | 30 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 |
| Temperature | -20 to +70 °C |
| 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 ACQJ40X30-10 Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC milling fixture during setup, allowing 20 to 30mm of outward travel to accommodate raw material variations.
Packaging Diverter Arms
Alter the extension length of a carton routing gate by up to 10mm to smoothly handle different box widths on a packaging line.
Assembly Press Positioning
Establish trial end positions for a press head without fabricating custom spacers, locking the depth precisely via the M12x1.25 adjuster nut.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X30-10 the Right Cylinder?
When sizing this actuator, stepping down to a 32mm bore yields 402.1N push at 0.5MPa, while stepping up to a 50mm bore provides 981.8N. If your machine never requires on-the-fly extend adjustments, a fixed-stroke ACQ40X30 will accomplish the same task. To order correctly, confirm the 40mm bore, 30mm full stroke, 10mm adjustment window, and whether you need the -S magnet or male M14x1.5 rod thread instead of the standard female M8x1.25.
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 ACQJ40X30-10 FAQ
It 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 30mm with a 10mm window, allowing an adjustable extend range of 20 to 30mm.
No, the adjuster only limits how far the rod extends, leaving the retract stroke identical. Since the piston area is unchanged, force remains the same as a standard ACQ. The cylinder uses a fixed NBR elastomer bumper for deceleration rather than an adjustable air cushion.
