Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-100
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-100 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 ACQJ32X80-100
The AirTAC ACQJ32X80-100 is a double-acting JIS compact cylinder with an external M12x1.25 threaded stop and lock nut that limits the extend end position. You can fine-tune the usable extend travel anywhere from 0 up to 80 mm directly on your equipment without swapping parts, while the retract stroke remains unaffected. Because the piston area stays the same, output force is identical to a standard ACQ of this bore.
This 32 mm bore unit features a 16 mm rod, PT1/8 porting, and a female M8x1.25 rod-end thread. It delivers 402.1 N of push force and 301.6 N of pull force at 0.5 MPa. The body incorporates fixed NBR elastomer bumpers at each end for end-of-stroke deceleration, and includes machined grooves for adding reed or solid-state magnetic switches later.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 80 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 ACQJ32X80-100 Is Used
Machining Fixture Stops
Dial in the exact extend position on a CNC machining fixture to accommodate raw part tolerances without machining new stop blocks.
Packaging Changeover
Rapidly reposition the end-of-stroke stop on a packaging line when switching between different carton or product sizes.
Prototype Positioning
Test various extend lengths on a prototype assembly rig to find the optimal end point before finalizing the mechanical design.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-100 the Right Cylinder?
If you need less thrust, the 25 mm bore yields 245.4 N push at 0.5 MPa, whereas stepping up to the 40 mm bore provides 628.3 N. A fixed-stroke ACQ32 is adequate if your extend end position never requires adjustment. For this model, confirm the 32 mm bore, 80 mm full stroke, 100 mm adjustment window, female M8x1.25 rod thread, and that no magnet (-S) is required.
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 ACQJ32X80-100 FAQ
It delivers 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. The usable extend range is 0-80 mm, adjustable via a 100 mm window, while the retract stroke remains fixed.
No. The external M12x1.25 threaded stop only changes the extend stroke length; the piston area is unchanged so force remains identical to a standard ACQ. End-of-travel deceleration is handled by fixed elastomer bumpers, not an adjustable air cushion.
