Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X25-10
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X25-10 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 25mm 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 ACQJ32X25-10
The AirTAC ACQJ32X25-10 is a double-acting JIS compact cylinder with a 32mm bore and a 25mm full stroke. An external M12x1.25 threaded stop with a lock nut limits the extend travel, allowing you to fine-tune the end position anywhere within a 15 to 25mm usable range directly on the machine. The retract stroke remains completely unaffected. Because the piston area stays the same, output force is identical to a standard ACQ of this bore.
This unit features a 16mm piston rod, a PT1/8 port, and a female M8x1.25 rod-end thread. It relies on a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. The body includes standard magnetic-switch grooves, though this specific configuration ships without a piston magnet.

| 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 |

| 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 ACQJ32X25-10 Is Used
Product Changeover Stops
Quickly alter the extend endpoint on packaging equipment when switching between different carton sizes, using the external stop to set new positions without swapping cylinders.
Trial End Positions
Dial in the exact clamping depth on assembly fixtures during prototype runs, testing various extend lengths from 15 to 25mm until the optimal travel is found.
Setup-Varying Fixtures
Adapt pressing stations to accommodate multiple part heights, adjusting the stroke length on the fly to accommodate varying raw material thicknesses.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X25-10 the Right Cylinder?
When sizing this 32mm bore actuator, consider the neighbouring bores: a 25mm unit yields 245.4N push, while a 40mm provides 628.3N, both at 0.5 MPa. If your extend position never needs on-the-fly shifting, a fixed-stroke ACQ32x25 is simpler and sufficient. To order the ACQJ correctly, confirm the 32mm bore, 25mm full stroke, 10mm adjust window, female rod thread, and whether you require the -S magnet option for sensor detection.
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 ACQJ32X25-10 FAQ
The usable extend range is 15-25mm (a 10mm window off the 25mm full stroke). Output force matches a standard ACQ: 402.1N push and 301.6N pull at 0.5 MPa, 562.9N push at 0.7 MPa, with a maximum push of 82 kgf at 1.0 MPa.
An external M12x1.25 threaded stop and lock nut mechanically limit how far the rod extends, shortening the stroke without changing piston area, so force remains identical. The retract stroke is unaffected, and end-of-travel deceleration relies on a fixed NBR elastomer bumper, not an adjustable air cushion.
