Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X45-10
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X45-10 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 45mm 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 ACQJ32X45-10
The AirTAC ACQJ32X45-10 is a double-acting JIS compact cylinder featuring a 32mm bore and a 45mm full stroke. An external threaded stop with a lock nut limits the extend end position, providing a 10mm adjustment window. This allows you to fine-tune the usable extend range from 35mm up to 45mm directly on the machine. The retract stroke remains completely unaffected by this mechanism.
Because the piston area is unchanged, the output force is identical to a standard ACQ of this bore, delivering 402.1N push and 301.6N pull at 0.5MPa. The cylinder body incorporates a fixed NBR elastomer bumper at each end for end-of-stroke deceleration and includes magnetic-switch grooves, though this specific configuration ships without a magnet. It uses a PT1/8 port and a 16mm piston rod with an M8x1.25 female rod-end thread.

| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X45-10 |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 45 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 ACQJ32X45-10 Is Used
Machining Fixture Stops
Dial in the extend position from 35 to 45mm on CNC machining fixtures to accommodate varying raw material lengths without swapping out cylinder hardware.
Packaging Changeover
Adjust the extend end stop rapidly during packaging line format changeovers to handle different carton depths, ensuring precise product alignment.
Assembly Press Tuning
Set trial end positions on automated assembly presses, allowing operators to tweak the 10mm window for delicate component insertion without reprogramming motion controllers.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X45-10 the Right Cylinder?
When sizing this 32mm bore actuator, consider the adjacent options: a 25mm bore yields 245.4N push, while a 40mm bore provides 628.3N push at 0.5MPa. If your extend position never varies, a fixed-stroke ACQ cylinder is sufficient. However, for product-changeover setups requiring variable end stops, this ACQJ32X45-10 is ideal. Confirm your ordering essentials: 32mm bore, 45mm full stroke, 10mm window, female rod thread, and whether you need the -S magnet option for position 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 ACQJ32X45-10 FAQ
The usable extend range is 35-45mm (45mm full stroke minus the 10mm window). Force is identical to a standard ACQ: 402.1N push and 301.6N pull at 0.5MPa, 562.9N push at 0.7MPa, with a maximum push of 82kgf at 1.0MPa.
The M12x1.25 external threaded stop with lock nut limits only the extend stroke length; retract is unaffected and force remains unchanged. The cylinder uses a fixed NBR elastomer bumper for deceleration. It does not hold the load on air loss, so an external rod lock or pilot-operated check valve is required for fail-safe holding.
