Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X35-10SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X35-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 35mm 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 ACQJ40X35-10SB
The AirTAC ACQJ40X35-10SB is a double-acting JIS compact cylinder featuring a 35mm full stroke and a 10mm external adjustment window, allowing the extend end position to be fine-tuned directly on your equipment from 25 to 35mm. Because the threaded stop only limits travel length, the output force remains identical to a standard ACQ of the same bore.
This variant includes a male M14x1.5 piston rod end for direct load coupling and a built-in piston magnet for position sensing. It utilizes a PT1/8 port and a 16mm rod diameter. Fixed elastomer bumpers absorb impact at both stroke ends, while the retract stroke remains completely unaffected by the extend adjuster.

| Bore size | Ø40 mm |
| Full stroke | 35 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 ACQJ40X35-10SB Is Used
Product Changeover Stops
Quickly modify the extend endpoint on packaging lines when switching between different container sizes, using the external M12x1.25 adjuster to dial in the exact 25 to 35mm reach.
Trial End Positions
Safely test clamping reach on new machining fixtures without machining new spacers, relying on the 628.3N push force to secure the workpiece.
Setup-Varying Fixtures
Adapt assembly tooling depths on the fly for varied component heights, ensuring the male M14x1.5 rod thread couples securely to the moving load.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X35-10SB the Right Cylinder?
When sizing this 40mm bore unit, note it delivers 628.3N of push force and 527.8N of pull force at 0.5MPa. If your application requires less force, stepping down to a 32mm bore provides 402.1N of push, whereas moving up to a 50mm bore yields 981.8N. Choose this adjustable model if your fixture setup or product changeover requires varying extend end positions; otherwise, a fixed-stroke ACQ cylinder is sufficient. Confirm your ordering essentials: 40mm bore, 35mm full stroke, 10mm window, magnet (S), and male rod thread (B).
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 ACQJ40X35-10SB FAQ
This cylinder has a 40mm bore and a 35mm full stroke with a 10mm adjustment window, giving a usable extend range of 25-35mm. It provides 628.3N push and 527.8N pull force at 0.5MPa, 879.6N push at 0.7MPa, and a maximum push of 128kgf at 1.0MPa. The force is identical to a standard ACQ because the adjuster only changes stroke length.
An external threaded stop with a lock nut limits the extend stroke without affecting the retract stroke. The cylinder uses fixed elastomer bumpers at both ends rather than adjustable air cushions. The included -S magnet allows you to use either reed or electronic solid-state switches in the standard grooves for position detection.
