Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-30S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-30S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 80mm 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 ACQJ32X80-30S
The ACQJ32X80-30S is a double-acting JIS compact cylinder with an external M12x1.25 threaded stop and lock nut that limits the extend stroke. You can fine-tune the forward end position on the machine across a 50 to 80 mm usable range without swapping parts. The retract stroke remains completely unaffected.
Because the piston area stays the same, output force is identical to a standard ACQ of this bore. The 32 mm body uses a PT1/8 port and a Ø16 mm rod. It includes a built-in piston magnet for sensing and fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration.

| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| 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 ACQJ32X80-30S Is Used
CNC Tooling Setups
Dial in the exact extend reach during initial CNC fixture probing, allowing operators to tweak the 50 to 80 mm forward stop without machining new spacers.
Packaging Format Changeover
Rapidly adjust the push-out distance when switching carton sizes on a packaging line, using the external lock nut to set the new end position in seconds.
Assembly Press Trial
Test different engagement depths for pressing bearings on an assembly line, finding the optimal stroke endpoint before locking the adjuster down.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-30S the Right Cylinder?
When sizing this unit, note a 32 mm bore yields 402.1 N push and 301.6 N pull at 0.5 MPa. Stepping down to a 25 mm bore drops push to 245.4 N, while a 40 mm bore raises it to 628.3 N. If your application never requires altering the forward position, a fixed-stroke ACQ cylinder is sufficient. To order this adjustable version, confirm the 32 mm bore, 80 mm full stroke, 30 mm window, the -S magnet, and the female M8x1.25 rod-end 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 ACQJ32X80-30S FAQ
This 32 mm bore cylinder has a usable extend range of 50 to 80 mm via a 30 mm adjustment window. 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.
An external M12x1.25 threaded screw with a lock nut mechanically limits the forward stroke, leaving retract unaffected. It relies on fixed NBR bumpers for deceleration, not a lock. If air pressure drops, the rod will drift; use an external rod lock or pilot-operated check valve for fail-safe holding. The -S magnet supports both reed and solid-state switches.
