Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X50-40S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X50-40S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 50mm 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 ACQJ32X50-40S
The AirTAC ACQJ32X50-40S is a double-acting JIS compact cylinder with a 32mm bore and 50mm full stroke. An external threaded stop with a lock nut limits the extend end position, providing a usable extend range of 10-50mm. The retract stroke remains unaffected. Because the piston area is unchanged, the force is identical to a standard ACQ of this bore.
This unit includes a built-in piston magnet (-S) compatible with reed or electronic solid-state switches. It features fixed elastomer bumpers at both ends, a 16mm piston rod, and PT1/8 ports. The external adjuster utilizes an M12x1.25 thread for precise on-machine end-position tuning.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 50 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 ACQJ32X50-40S Is Used
Multi-Size Part Clamping
Dial in the extend stop from 10 to 50mm to clamp varying part widths on a machining fixture without swapping cylinder bodies.
Product Diversion Stops
Adjust the end position on the fly for different carton lengths on a packaging conveyor line during rapid product changeovers.
Prototype Press Testing
Set trial end positions for a laboratory press, fine-tuning the extend distance to test assembly forces without re-engineering the tooling.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X50-40S the Right Cylinder?
If you require less force, the 25mm bore version provides 245.4N push at 0.5 MPa, while stepping up to the 40mm bore yields 628.3N push. Choose this 32mm model for applications needing around 400N of push force with a maximum 50mm stroke. A fixed-stroke ACQ is sufficient if your extend position never changes. When ordering, confirm the 32mm bore, 50mm full stroke, 40mm adjuster window, the -S magnet option, and the 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 ACQJ32X50-40S FAQ
The force is identical to a standard ACQ: 402.1N push and 301.6N pull at 0.5 MPa, 562.9N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The usable extend range is 10-50mm (50mm full stroke minus the 40mm adjuster window).
The external M12x1.25 threaded stop and lock nut mechanically limit the extend distance, changing only the stroke length, not the force. The cylinder uses fixed elastomer bumpers at each end rather than adjustable air cushions. The -S magnet works with reed or electronic solid-state switches for position sensing.
