Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-30
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-30 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 200mm 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 ACQJ40X200-30
The ACQJ40X200-30 is a double-acting, single-rod JIS compact cylinder engineered for on-machine extend stroke adjustment. An external M12x1.25 threaded stop with a lock nut permits you to shorten the forward travel by up to 30 mm. This yields a usable extend span of 170 to 200 mm, while the retract stroke remains totally unaffected.
Because the adjuster solely restricts travel length, the piston area stays constant, meaning force remains identical to a standard ACQ of this bore (628.3 N push at 0.5 MPa). This specific 200 mm configuration is a long-stroke, made-to-order variant exceeding the 100 mm standard maximum for this bore size. It retains the fixed NBR elastomer bumpers and sensor grooves, though this unit ships without a magnet.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø40 mm |
| Full stroke | 200 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 ACQJ40X200-30 Is Used
Machining Fixture Stops
Dial in the exact extend position for varying part lengths on a CNC milling fixture without machining custom spacers.
Product Changeover Diverter
Adjust the extend reach of a pneumatic sorting gate to accommodate different package widths on a packaging line.
Press Trial Positioning
Set trial end positions on an assembly press to test engagement depths before finalizing a hard mechanical stop.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-30 the Right Cylinder?
When sizing this actuator, consider the ACQJ32X50-30 (offering 402.1 N push at 0.5 MPa) for lighter duties, or step up to the ACQJ50X100-50 (providing 981.8 N push) if your application demands greater thrust. If your setup never requires altering the end position, a fixed-stroke ACQ cylinder will suffice and avoids the extra adjuster hardware. For ordering, confirm the 40 mm bore, 200 mm full stroke, 30 mm window, female M8x1.25 rod-end thread, and PT1/8 porting.
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 ACQJ40X200-30 FAQ
The usable extend range is 170-200 mm (full 200 mm stroke minus the 30 mm window). Force is identical to a standard ACQ: 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push at 0.7 MPa, and a maximum push of 128 kgf at 1.0 MPa.
The external M12x1.25 threaded stop with lock nut only limits how far the rod extends; it does not alter piston area, so thrust remains unchanged. Deceleration relies on fixed NBR elastomer bumpers at both ends, not adjustable air cushions. Note that this model ships without a magnet.
