Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X50-20
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X50-20 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 ACQJ32X50-20
The AirTAC ACQJ32X50-20 is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. You get a usable extend range of 30-50mm, achieved by subtracting up to 20mm from the 50mm full stroke. The retract stroke remains completely unaffected by this mechanism.
Because the adjuster only alters travel length and not piston area, force is identical to a standard ACQ of this bore. The 32mm bore uses a PT1/8 port, a 16mm rod, and an M12x1.25 adjuster thread. It features a fixed NBR elastomer bumper at each end for deceleration, though this specific unit ships without a magnet despite having standard sensor grooves.

| 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 |

| 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 ACQJ32X50-20 Is Used
Product Changeover Stops
Set new extend endpoints on packaging lines when switching carton sizes, using the lock nut to dial in the exact 30-50mm position without swapping cylinders.
Assembly Machine Setup
Fine-tune pressing or clamping positions on automated assembly stations during initial commissioning to find the optimal travel distance quickly.
Fixture Alignment
Adjust the extend stop on machining fixtures to accommodate varying part tolerances, ensuring the rod extends exactly where needed every cycle.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X50-20 the Right Cylinder?
If you need less push force, the 25mm bore delivers 245.4N at 0.5MPa; stepping up to the 40mm bore provides 628.3N. Choose this adjustable model when you need trial end positions during setup or product changeovers; if your machine never requires stroke tuning, a fixed ACQ cylinder suffices. Confirm ordering essentials: 32mm bore, 50mm full stroke, 20mm window, female rod thread M8x1.25, and no magnet.
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 ACQJ32X50-20 FAQ
It delivers 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 full stroke is 50mm with a 20mm adjustable window, giving a usable extend range of 30-50mm.
The external M12x1.25 threaded stop with lock nut limits only the extend travel, leaving the retract stroke and force unchanged. The cylinder uses fixed elastomer bumpers instead of air cushions, and because it lacks a rod lock, it will drift on air loss; use an external rod lock for fail-safe holding.
