Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X50-10SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X50-10SB 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 ACQJ32X50-10SB
The AirTAC ACQJ32X50-10SB is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut on the extend side. This mechanism allows you to fine-tune the extend end position directly on the machine without swapping parts. You get a usable extend range of 40-50 mm (a 50 mm full stroke shortened by the 10 mm window), while the retract stroke remains completely unaffected.
Because the piston area stays constant, output force is identical to a standard ACQ of this bore. The 32 mm bore delivers 402.1 N push and 301.6 N pull at 0.5 MPa. It includes an NBR fixed elastomer bumper at each end for deceleration and integrated grooves for magnetic switches. The -S magnet supports reed or solid-state sensors, and the -B male M14x1.5 rod end couples directly to your load.

| 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 ACQJ32X50-10SB Is Used
Machining Fixture Clamping
Dial in the exact clamping position on a machining fixture during setup. The external stop lets you compensate for varying part tolerances without machining custom spacers.
Product Changeover Stops
Adjust the extend endpoint rapidly on a packaging line when switching between product formats. The 10 mm window provides enough travel to handle multiple carton sizes.
Assembly Press Trial
Establish the precise end position for an assembly press during prototype runs. You can test different engagement depths on the machine and lock the nut once the optimal stroke is found.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X50-10SB the Right Cylinder?
Choosing this 32 mm bore yields 402.1 N push force at 0.5 MPa. If you need less force, stepping down to a 25 mm bore provides 245.4 N push, or moving up to a 40 mm bore gives 628.3 N. A fixed-stroke ACQ cylinder is sufficient if your extend end position never requires adjustment. When ordering, confirm the 32 mm bore, 50 mm full stroke, 10 mm window, the -S magnet for sensing, and the -B male M14x1.5 rod thread. The port size is PT1/8.
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 ACQJ32X50-10SB FAQ
It provides a push force of 402.1 N and a pull force of 301.6 N at 0.5 MPa, and 562.9 N push at 0.7 MPa. The maximum push force is 82 kgf at 1.0 MPa. The full stroke is 50 mm, and with the 10 mm adjustable window, the usable extend range is 40-50 mm.
The external M12x1.25 threaded stop with a lock nut limits how far the rod extends, shortening the extend stroke only. It does not alter the piston area, so the output force remains identical to a standard ACQ. The retract stroke is unaffected, and fixed NBR bumpers handle deceleration at stroke ends.
