Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-30B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-30B 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 ACQJ32X100-30B
The AirTAC ACQJ32X100-30B is a double-acting JIS compact cylinder with a 32mm bore and 100mm full stroke. An external M12x1.25 threaded stop and lock nut limits the extend end position, providing a usable extend range of 70-100mm without swapping components. The retract stroke remains completely unaffected by this adjustment. Because the piston area is unchanged, force output is identical to a standard ACQ of this bore.
This specific configuration includes a male M14x1.5 rod-end thread (-B) for direct load coupling and uses a PT1/8 port. It features fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions. The body incorporates magnetic-switch grooves, though this model ships without a magnet. Operating pressure spans 0.15-1.0 MPa with speeds from 30-500 mm/s.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 100 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 ACQJ32X100-30B Is Used
Tooling Changeovers
Dial in the extend stop from 70 to 100mm during machining fixture swaps to accommodate varying part lengths without machining new spacers.
Assembly Press Setup
Test and set precise clamping end positions on automated presses, using the lock nut to secure the exact 32mm bore clamping depth.
Carton Flap Folding
Adjust the extend stroke on packaging line folders to handle different box heights on the fly, ensuring consistent folding without retooling.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-30B the Right Cylinder?
If your setup requires less push force at 0.5 MPa, the 25mm bore variant delivers 245.4N push and 188.9N pull. For heavier demands, the 40mm bore provides 628.3N push and 527.8N pull. A standard fixed-stroke ACQ32X100 is sufficient if your end position never requires field tuning. When ordering this unit, verify the 32mm bore, 100mm full stroke, 30mm adjuster window, the male M14x1.5 rod thread, and confirm no internal magnet is needed.
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 ACQJ32X100-30B FAQ
It delivers 402.1N push and 301.6N pull at 0.5 MPa, 562.9N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The full stroke is 100mm, and the external M12x1.25 adjuster allows the extend stroke to be shortened by up to 30mm, yielding a usable extend range of 70-100mm.
The external threaded stop limits how far the rod extends, shortening the stroke length only; it does not alter the piston area, so force remains identical to a standard ACQ. Deceleration is handled by fixed NBR elastomer bumpers at each end, not adjustable air cushions. Note that this model lacks a magnet and will not hold its load on air loss without an external rod lock.
