Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-10S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-10S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 35mm 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 ACQJ32X35-10S
The AirTAC ACQJ32X35-10S is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend end position. You can fine-tune the usable extend stroke from 25 mm up to the full 35 mm directly on the machine, while the retract stroke remains unaffected. It includes a built-in piston magnet (-S) for position sensing.
Because the adjuster only alters stroke length and not the piston area, output force stays identical to a standard ACQ of the same bore. At 0.5 MPa it delivers 402.1 N of push force and 301.6 N of pull force. The unit uses a PT1/8 port, a 16 mm rod, and fixed elastomer bumpers at both ends for end-of-stroke deceleration.

| Bore size | Ø32 mm |
| Full stroke | 35 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 ACQJ32X35-10S Is Used
Machining Fixture Stops
Dial in the extend stroke from 25 to 35 mm on a CNC machining fixture to accommodate raw part tolerances without machining new spacer blocks.
Packaging Changeover
Adjust the extend end position during product format changeovers on a packaging line, hitting exact carton push-off points rapidly.
Prototype Positioning
Test varying extend end stops on a prototype assembly rig to find the optimal clamping distance before finalizing the mechanical design.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-10S the Right Cylinder?
This 32 mm bore provides 402.1 N push at 0.5 MPa, sitting between the smaller 25 mm bore (245.4 N push) and the larger 40 mm bore (628.3 N push). If your application never requires end-position variation, a fixed-stroke ACQ cylinder is sufficient. When ordering, confirm the 35 mm full stroke, the 10 mm adjuster window, the -S magnet, 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 ACQJ32X35-10S FAQ
The usable extend range is 25-35 mm (full 35 mm stroke minus the 10 mm window). It provides 402.1 N push and 301.6 N pull at 0.5 MPa, 562.9 N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The port is PT1/8 and the external adjuster thread is M12x1.25.
No, the external stop only limits how far the rod extends, so the force is identical to a standard ACQ. The piston decelerates against fixed elastomer bumpers at both ends. The -S magnet allows tracking with either reed or electronic solid-state switches.
