Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X10-10
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X10-10 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 10mm 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 ACQJ40X10-10
The AirTAC ACQJ40X10-10 is a double-acting JIS compact cylinder with a 10mm full stroke and a 10mm adjustable extend window. An external M12x1.25 threaded stop with a lock nut lets you set the extend end position from 0 to 10mm directly on the machine. The retract stroke remains fixed and unaffected.
Because the piston area is unchanged, force output is identical to a standard ACQ bore 40. You get 628.3N push and 527.8N pull at 0.5MPa. The body features fixed elastomer bumpers at each end and integrated magnetic-switch grooves, though this specific configuration ships without the magnet.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø40 mm |
| Full stroke | 10 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 ACQJ40X10-10 Is Used
Fixture Setup Tuning
Dial in the exact clamping reach during initial fixture setup without machining custom spacers.
Product Changeover Stops
Quickly modify the extend endpoint on a packaging line when switching between different carton sizes.
Trial End Positions
Test various pressing depths on a small assembly rig to find the optimal contact point before locking the nut.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X10-10 the Right Cylinder?
When sizing this 40mm bore, dropping to a 32mm bore yields 402.1N push at 0.5MPa, while stepping up to a 50mm bore provides 981.8N. If your extend position never varies, a fixed-stroke ACQ cylinder is sufficient. To order, confirm the 40mm bore, 10mm full stroke, 10mm window, female M8x1.25 rod end, and PT1/8 port.
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 ACQJ40X10-10 FAQ
The usable extend range is 0-10mm. Force output matches a standard ACQ: 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 adjuster changes stroke length only, not force.
An M12x1.25 threaded stop and lock nut mechanically limits the extend distance, while fixed elastomer bumpers decelerate the piston at both ends. This is a plain cylinder; it will not hold a load on air loss, so use an external rod lock for fail-safe holding.
