Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X40-10SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X40-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 40mm 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 ACQJ32X40-10SB
The AirTAC ACQJ32X40-10SB is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the EXTEND end position. With a full stroke of 40mm and an adjustment window of 10mm, you can fine-tune the usable extend range from 30mm up to 40mm directly on the machine. The RETRACT stroke remains completely unaffected.
Because the piston area is unchanged, the output force is identical to a standard ACQ of this bore, delivering 402.1N push at 0.5MPa. The rod end is male-threaded M14x1.5 for direct coupling, and the included -S magnet works with reed or solid-state switches. Deceleration is handled by a fixed NBR elastomer bumper at each end, not an adjustable air cushion.

| 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 ACQJ32X40-10SB Is Used
Fixture Position Calibration
Dial in the exact extend stop from 30 to 40mm during initial fixture setup without machining custom spacers or swapping cylinders.
Product Changeover Stops
Quickly shorten the extend endpoint by up to 10mm on a packaging line when transitioning between different carton sizes.
Trial End Positions
Test clamping pressure and contact points on an assembly press by micro-adjusting the male M14x1.5 rod extension safely within the 10mm window.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X40-10SB the Right Cylinder?
This 32mm bore provides 402.1N push and 301.6N pull force at 0.5MPa. Stepping down to a 25mm bore drops the push to 245.4N, while moving up to a 40mm bore increases it to 628.3N. If your setup never requires end-position tuning, a fixed-stroke ACQ32x40 cylinder is sufficient. When ordering this adjustable version, confirm the 32mm bore, 40mm full stroke, 10mm window, the -S magnet for sensors, 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 ACQJ32X40-10SB 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 40mm with a 10mm adjustment window, allowing a usable extend range of 30-40mm. The retract stroke is unaffected.
An external M12x1.25 threaded stop with a lock nut limits how far the rod extends, shortening the stroke length only. It does not change the piston area, so force remains identical to a standard ACQ. End-of-travel deceleration relies on a fixed elastomer bumper, not an adjustable air cushion.
