Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-50SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-50SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 60mm 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 ACQJ40X60-50SB
The AirTAC ACQJ40X60-50SB is a double-acting JIS compact cylinder featuring an external threaded stop and lock nut that limits the extend end position. With a 60mm full stroke and a 50mm adjustment window, the usable extend range is 10-60mm. The retract stroke remains completely unaffected. Because the piston area is unchanged, output force equals a standard ACQ of the same bore.
This bore 40mm unit pushes 628.3N at 0.5MPa and pulls 527.8N. It includes a male M14x1.5 rod end, a PT1/8 port, and fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration. The integrated piston magnet works with reed or solid-state switches, and the M12x1.25 adjuster thread allows on-machine end-position tuning without swapping parts.

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 ACQJ40X60-50SB Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC fixture during setup, shortening the extend stroke from 60mm down to 10mm to accommodate varying part geometries.
Carton Changeover Flaps
Adapt a packaging line to different box sizes rapidly by rotating the external stopper, setting the folding arm extension precisely without changing hardware.
Assembly Press Trial
Test drive seating depths on an assembly press by adjusting the extend limit in small increments, preventing damage to delicate components during process validation.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-50SB the Right Cylinder?
If you need less push force, the 32mm bore yields 402.1N at 0.5MPa, while the 50mm bore provides 981.8N for heavier loads. A fixed-stroke ACQ is sufficient if your extend position never requires tweaking. Confirm your ordering essentials: 40mm bore, 60mm full stroke, 50mm window, S magnet, and 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 ACQJ40X60-50SB FAQ
At 0.5MPa it pushes 628.3N and pulls 527.8N; at 0.7MPa push is 879.6N. Maximum push is 128kgf at 1.0MPa. The 60mm full stroke has a 50mm window, giving a usable extend range of 10-60mm.
No, the external M12x1.25 stopper changes stroke length only, so force remains identical to a standard ACQ. Fixed elastomer bumpers decelerate the rod near ends, but a plain cylinder drifts on air loss, so use an external rod lock for fail-safe holding.
