Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-30
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-30 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 100mm 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 ACQJ32X100-30
The AirTAC ACQJ32X100-30 is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. You can fine-tune the usable extend range from 70 mm up to the full 100 mm stroke directly on your equipment without swapping parts. The retract stroke remains completely unaffected by this adjustment.
Because the piston area is unchanged, output force equals a standard ACQ of the same bore: 402.1 N push and 301.6 N pull at 0.5 MPa. The unit features a fixed NBR elastomer bumper at each end for end-of-stroke deceleration and integrated sensor grooves, though this specific configuration ships without a magnet. It operates at pressures from 0.15 to 1.0 MPa with a PT1/8 port and a 16 mm piston rod.

| 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 ACQJ32X100-30 Is Used
Machining Fixture Stops
Dial in the exact 70-100 mm extend end position on a machining fixture to accommodate raw part length variations without fabricating new stop blocks.
Packaging Diverters
Adjust the diverting stroke on a packaging conveyor line during product format changeovers, ensuring cartons of varying widths are guided correctly.
Assembly Press Positioning
Set trial end positions on an electronic assembly press, allowing operators to tweak the extend distance for seating different connector types.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-30 the Right Cylinder?
If your application requires less push force at 0.5 MPa, the ACQJ25 model provides 245.4 N; for higher force demands, the ACQJ40 bore offers 628.3 N. Choose this adjustable version only if your process requires varying the extend end position within that 70-100 mm window; otherwise, a fixed-stroke ACQ cylinder is simpler. When ordering, verify the 32 mm bore, 100 mm full stroke, 30 mm adjuster window, female M8x1.25 rod-end thread, and confirm whether you need the -S magnet option for position sensing.
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 ACQJ32X100-30 FAQ
The usable extend range is 70-100 mm (full 100 mm stroke minus up to 30 mm). Force is identical to a standard ACQ: 402.1 N push and 301.6 N pull at 0.5 MPa, 562.9 N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa.
No, the external M12x1.25 threaded stop only limits how far the rod extends; the retract stroke remains unaffected and the force is unchanged since the piston area is the same. The cylinder uses a fixed elastomer bumper for deceleration and does not hold loads on air loss, so an external rod lock is needed for fail-safe holding.
