Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X30-10SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X30-10SB 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 ACQJ40X30-10SB
The AirTAC ACQJ40X30-10SB is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut to fine-tune the extend end position. With a 10mm adjustment window, the usable extend range runs from 20mm up to the full 30mm stroke. The retract stroke remains completely unaffected. Because the piston area is unchanged, the output force is identical to a standard ACQ of this bore.
This unit includes a male M14x1.5 rod-end thread for direct load coupling and a built-in piston magnet for position sensing. It uses a PT1/8 port and relies on fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions. Operating pressure ranges from 0.15 to 1.0 MPa.

| 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 ACQJ40X30-10SB Is Used
Machining Fixture Stops
Dial in the exact extend position of a 40mm clamping pin on a CNC machining fixture without machining new spacers for different part families.
Packaging Changeover
Rapidly adjust the extend endpoint of a product diverting gate during format size changeovers on a packaging line to accommodate varying carton widths.
Assembly Press Trials
Establish the precise end position for a pressing operation during new product introduction on an assembly line, safely testing stroke limits before finalizing the mechanical setup.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X30-10SB the Right Cylinder?
If your application requires less push force, the 32mm bore variant provides 402.1N push at 0.5 MPa, whereas stepping up to a 50mm bore yields 981.8N. This 40mm bore delivers 628.3N push and 527.8N pull at 0.5 MPa, with a maximum push capacity of 128kgf at 1.0MPa. A standard fixed-stroke ACQ cylinder is sufficient if your extend position never needs field adjustments. When ordering this adjustable model, confirm the 40mm bore, 30mm full stroke, 10mm window, the S magnet option, and the B male rod 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 ACQJ40X30-10SB FAQ
The usable extend range is 20-30mm (30mm full stroke minus the 10mm window). Force is identical to a standard ACQ: push is 628.3N and pull is 527.8N at 0.5MPa, push is 879.6N at 0.7MPa, and maximum push is 128kgf at 1.0MPa.
An external M12x1.25 threaded stop with a lock nut limits the extend stroke length without altering piston area, so force remains unchanged. The cylinder uses fixed elastomer bumpers rather than adjustable air cushions. The included S magnet works with both reed and solid-state electronic switches.
