Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-40S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-40S 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 ACQJ32X150-40S
The ACQJ32X150-40S is a double-acting JIS compact cylinder with a 150mm stroke and a built-in magnet. An external M12x1.25 threaded stop and lock nut restricts the extend end position, providing a usable forward range of 110 to 150mm. The retract distance remains completely unaffected by this adjustment.
Because the piston area stays the same, output force is identical to a standard ACQ of this bore, yielding 402.1N push and 301.6N pull at 0.5MPa. This 32mm bore variant features a 16mm rod, PT1/8 porting, and fixed NBR elastomer bumpers. Note that the 150mm length is a made-to-order long-stroke configuration, exceeding the standard 100mm maximum for this bore size.

| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-40S |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 150 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 ACQJ32X150-40S Is Used
Machining Fixture Stops
Dial in exact clamping reach on a CNC mill to accommodate different raw casting lengths without fabricating custom spacer blocks.
Assembly Line Changeover
Quickly reposition the extend limit for a new product variant on a modular conveyor line, cutting setup time between production runs.
Prototype Positioning
Establish optimal end-of-travel coordinates during robotic testing by fine-tuning the external stop nut instead of reprogramming the PLC.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-40S the Right Cylinder?
At 0.5MPa, this 32mm bore yields 402.1N of push force. If your application requires less force, stepping down to a 25mm bore provides 245.4N, while moving up to a 40mm bore offers 628.3N. If your end position never varies, a fixed-stroke ACQ32X150 is sufficient. When ordering, confirm the 32mm bore, 150mm full stroke, 40mm adjuster 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 ACQJ32X150-40S FAQ
This cylinder has a 150mm full stroke with a 40mm adjustable window, giving a usable extend range of 110-150mm. The force is identical to a standard ACQ: 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.
An external M12x1.25 threaded stop with a lock nut limits the extend distance without altering the piston area, so force remains unchanged. The retract stroke is unaffected. Deceleration is handled by fixed elastomer bumpers, not adjustable air cushions. The included -S magnet works with both reed and electronic solid-state switches.
