Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X40-10
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X40-10 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 40mm 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 ACQJ32X40-10
The AirTAC ACQJ32X40-10 is a double-acting JIS compact cylinder featuring an external threaded stop and lock nut that limits the extend stroke. You can fine-tune the usable extend range from 30 to 40 mm on the machine, while the retract stroke remains unaffected. The adjuster features an M12x1.25 thread.
Because the piston area is unchanged, force output is identical to a standard ACQ of this bore, delivering 402.1 N of push force at 0.5 MPa. The body includes fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration and retains sensor grooves, though this specific configuration ships without a magnet.

| Port size | PT1/8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| 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 ACQJ32X40-10 Is Used
Product Changeover Stops
Dial in the extend position from 30 to 40 mm during packaging line format changes without machining new parts.
Trial End Positions
Test clamping endpoints on machining fixtures by tweaking the external M12x1.25 adjuster until the optimal reach is found.
Setup-Varying Fixtures
Accommodate varying carton sizes on sealing equipment by shortening the extend stroke up to 10 mm directly on the machine.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X40-10 the Right Cylinder?
Choosing a 32 mm bore yields 402.1 N push and 301.6 N pull at 0.5 MPa. If your application requires less force, stepping down to a 25 mm bore provides 245.4 N push, while moving up to a 40 mm bore offers 628.3 N push. If the extend position never needs variation, a fixed-stroke ACQ cylinder suffices. When ordering, confirm the 32 mm bore, 40 mm full stroke, 10 mm window, female rod-end thread (M8x1.25), and whether a magnet (-S) is needed for 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 ACQJ32X40-10 FAQ
It provides 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 full stroke is 40 mm with a 10 mm window, allowing an adjustable extend range of 30-40 mm.
The external threaded stop limits the extend stroke without changing the piston area, so force remains identical to a standard ACQ. The retract stroke is unaffected, and fixed NBR bumpers decelerate the load at stroke ends rather than adjustable air cushions.
