Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X10-10B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X10-10B 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 ACQJ40X10-10B
The ACQJ40X10-10B is a double-acting JIS compact cylinder with a 10mm full stroke and a 10mm extend adjustment window, giving a usable extend range of 0-10mm. An external M12x1.25 threaded stop and lock nut lets you set the extend end position directly on the machine, while the retract stroke remains completely unaffected.
Because the piston area is unchanged, output force matches a standard ACQ exactly, delivering 628.3N push and 527.8N pull at 0.5MPa. This male-rod (-B) variant features an M14x1.5 thread for direct load coupling, a 16mm rod diameter, and fixed elastomer NBR bumpers at both ends for end-of-stroke deceleration.

| 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 ACQJ40X10-10B Is Used
Short-Stroke Clamping
Dial in the exact 0-10mm clamping extension on machining fixtures to accommodate varying part tolerances without swapping cylinders.
Product Changeover Stops
Quickly reposition the extend stop for different packaging widths on a filling line, using the external M12x1.25 adjuster to hit new end positions instantly.
Trial End Positions
Test precise ejection distances on automated assembly equipment, fine-tuning the stroke in millimetres before locking down the final production setup.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X10-10B the Right Cylinder?
If your setup only needs a fixed 10mm extension, a standard ACQ40X10 will suffice without the external stop hardware. When sizing pneumatics, note the neighbouring bores: a 32mm bore provides 402.1N push at 0.5MPa, while a 50mm bore yields 981.8N. To order this adjustable unit correctly, confirm the 40mm bore, 10mm full stroke, 10mm window, the male M14x1.5 rod thread, and the absence of a magnet.
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 ACQJ40X10-10B FAQ
It delivers 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 10mm with a 10mm adjustment window, allowing a usable extend range of 0-10mm.
The external M12x1.25 threaded stop mechanically limits the extension distance without altering piston area, so force remains identical to a standard ACQ. It uses fixed elastomer bumpers for deceleration, but it will not hold the load on air loss; you need an external rod lock or pilot-operated check valve for fail-safe holding.
