Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X75-30SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X75-30SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 75mm 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 ACQJ32X75-30SB
The AirTAC ACQJ32X75-30SB is a double-acting, single-rod JIS compact cylinder featuring a 32mm bore and a 75mm full stroke. An external threaded stop with a lock nut limits the extend end position, providing a usable forward range of 45 to 75mm. The retract stroke remains completely unaffected. Because the piston area is unchanged, the output force is identical to a standard ACQ of this size.
This model includes the -S piston magnet for compatibility with reed or solid-state electronic switches, and the -B male rod-end thread (M14x1.5) for direct load coupling. It features fixed elastomer bumpers at both ends, a PT1/8 port, and an M12x1.25 adjuster thread. Operating pressure ranges from 0.15 to 1.0 MPa.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 75 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 302 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 ACQJ32X75-30SB Is Used
Machining Fixture Clamps
Dial in the exact clamping reach on a CNC fixture without machining new spacers, accommodating varying raw material thicknesses directly at the machine.
Carton Sealing Stops
Adjust the extend length on the fly for different box sizes on a packaging line, ensuring the sealing head contacts the flap perfectly every time.
Press Die Setup
Find the ideal trial end position for a light-duty assembly press, tweaking the 45-75mm range to test engagement depths before finalizing the cycle.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X75-30SB the Right Cylinder?
When sizing this actuator, consider the 32mm bore alongside its neighbors. Stepping down to a 25mm bore drops the 0.5 MPa push force to 245.4N, while stepping up to a 40mm bore increases it to 628.3N. If your end-position never varies, a fixed-stroke ACQ cylinder suffices. For the ACQJ32X75-30SB, confirm the 32mm bore, 75mm full stroke, 30mm adjust window, the -S magnet, 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 ACQJ32X75-30SB FAQ
The usable extend range is 45-75mm (75mm full stroke minus the 30mm window). Force is identical to a standard ACQ: push is 402.1N and pull is 301.6N at 0.5 MPa, push is 562.9N at 0.7 MPa, and max push is 82kgf at 1.0 MPa.
The external M12x1.25 threaded stop and lock nut limit only the extend length, leaving retract unchanged. The cylinder uses fixed elastomer bumpers, not adjustable air cushions. The -S magnet works with reed or electronic switches for position sensing.
