Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-30
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-30 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 150mm 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 ACQJ32X150-30
The ACQJ32X150-30 is a double-acting JIS compact cylinder with a 150mm full stroke and a 30mm external adjustment window. An external M12x1.25 threaded stop and lock nut restricts the extend travel, yielding a usable forward range of 120 to 150mm. The retract distance remains completely unaffected by this mechanism. This unit is classified as a long-stroke made-to-order variant because the 150mm length exceeds the 100mm standard maximum for a 32mm bore.
Because the pneumatic piston area stays constant, output force is identical to a standard ACQ of the same size. At 0.5MPa it generates 402.1N of push and 301.6N of pull, increasing to 562.9N at 0.7MPa. The body incorporates fixed NBR elastomer bumpers for end-of-stroke deceleration rather than adjustable pneumatic cushions. A 16mm rod and PT1/8 porting complete the assembly.

| 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 ACQJ32X150-30 Is Used
Machining Fixture Clamps
Dial in the exact clamping reach on a CNC milling fixture during setup, compensating for varying raw material thicknesses without swapping out cylinder hardware.
Product Changeover Stops
Modify the extend endpoint on a packaging line conveyor stop when transitioning between different carton sizes, achieving rapid format changes.
Prototype Positioning
Establish optimal trial end positions on a new automated test rig, tweaking the 120-150mm extend window until the exact motion sequence is proven.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-30 the Right Cylinder?
When sizing this actuator, stepping down to a 25mm bore drops the 0.5MPa push force to 245.4N, while stepping up to a 40mm bore raises it to 628.3N. If your machine never requires end-position adjustments, a fixed-stroke ACQ32x150 will serve the same role with less complexity. To order this adjustable version correctly, confirm the 32mm bore, 150mm full stroke, 30mm window, female M8x1.25 rod thread, and PT1/8 porting. This SKU ships without a magnet; if sensors are needed, specify the -S option.
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 ACQJ32X150-30 FAQ
The full stroke is 150mm with a 30mm adjustable window, giving a usable extend range of 120-150mm. It produces 402.1N push and 301.6N pull at 0.5MPa, 562.9N push at 0.7MPa, and a maximum push of 82kgf at 1.0MPa. The rod is 16mm, the port is PT1/8, and the external adjuster thread is M12x1.25.
No, the adjuster only changes the extend stroke length, not the piston area, so force remains identical to a standard ACQ. Deceleration is handled by fixed NBR elastomer bumpers at both ends rather than adjustable air cushions. Note that this model ships without a magnet; adding the -S option enables reed or solid-state sensors in the body grooves.
