Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X25-10S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X25-10S 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 ACQJ32X25-10S
The AirTAC ACQJ32X25-10S is a double-acting JIS compact cylinder featuring an external extend-stop mechanism. A threaded rod with a lock nut lets you fine-tune the outward travel from 15 mm to the full 25 mm directly on the machine, while the return stroke remains completely unaffected. This on-machine adjustability eliminates the need to swap components when dialing in final end positions.
Because the piston diameter stays constant, output force equals a standard ACQ equivalent, delivering 402.1 N push at 0.5 MPa. The 32 mm bore uses a PT1/8 port and a 16 mm rod. It integrates fixed NBR elastomer bumpers at both ends for end-of-travel deceleration, rather than adjustable air cushions. The built-in magnet (-S) supports both reed and solid-state sensing electronics.

| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X25-10S |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 25 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 ACQJ32X25-10S Is Used
Fixture Alignment
Dialing in exact clamping reach on machining fixtures where material thickness varies slightly, using the external stop to set the 15 to 25 mm outward travel.
Product Changeover
Adjusting end stops on packaging lines during format changes, allowing operators to reposition the extend limit without disassembling the pneumatic setup.
Prototype Testing
Testing trial end positions on new assembly machinery, fine-tuning the outward stroke dynamically to find the optimal pressing distance.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X25-10S the Right Cylinder?
When sizing this 32 mm bore actuator, consider the 25 mm bore yielding 245.4 N push, or stepping up to a 40 mm bore for 628.3 N push at 0.5 MPa. If your application never requires variable end positions, a fixed-stroke ACQ cylinder provides the same holding power in a simpler package. To order this adjustable version correctly, confirm the 32 mm bore, 25 mm full stroke, 10 mm adjustment window, the -S magnet option, and the default 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 ACQJ32X25-10S 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 usable extend range is 15-25 mm (a 25 mm full stroke minus a 10 mm adjustment window).
No, the external M12x1.25 threaded stop only limits the extend length, not the piston area, so force remains identical to a standard ACQ. The cylinder uses fixed elastomer bumpers for deceleration and includes a magnet for reed or solid-state sensors.
