Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X10-10S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X10-10S 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 ACQJ40X10-10S
The AirTAC ACQJ40X10-10S is a double-acting JIS compact cylinder with a 10 mm full stroke and an external extend stop. A threaded rod with an M12x1.25 pitch and lock nut lets you fine-tune the extend end position on the machine, yielding a usable extend range of 0 to 10 mm. The retract stroke remains completely unaffected by this adjustment.
Because the piston area is unchanged, the output force matches a standard ACQ of the same bore exactly. You get 628.3 N of push and 527.8 N of pull at 0.5 MPa. The body features fixed NBR elastomer bumpers at each end for end-of-stroke deceleration, and the -S option adds a piston magnet compatible with reed or solid-state electronic switches.

| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X10-10S |
|---|---|
| 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 |
| 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 ACQJ40X10-10S Is Used
Fixture Changeovers
Dial in the extend stop from 0 to 10 mm when swapping machining fixtures on a CNC lathe loader, ensuring the rod meets the new part height perfectly.
Carton Positioning
Adjust the pusher end point on a packaging conveyor to handle varying box widths without swapping out the physical cylinder body.
Press Trial Stops
Set trial end positions during a metal straightening press setup to test deflection limits safely before finalizing the mechanical hard stop.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X10-10S the Right Cylinder?
If you need slightly less push force, the 32 mm bore delivers 402.1 N at 0.5 MPa, while the 50 mm bore steps up to 981.8 N. A fixed-stroke ACQ cylinder is adequate if your end position never varies. When ordering this adjustable version, confirm the 40 mm bore, 10 mm full stroke, 10 mm window, the -S magnet, and the female M8x1.25 rod-end thread.
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 ACQJ40X10-10S FAQ
It provides 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. The full stroke is 10 mm with a 10 mm window, allowing an adjustable extend range of 0 to 10 mm.
No, the adjuster only limits how far the rod extends, leaving the retract stroke unaffected. The force is identical to a standard ACQ because the piston area is unchanged. Fixed elastomer bumpers handle deceleration, and the -S magnet works with reed or solid-state switches.
