About the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-20
The AirTAC ACQJ32X35-20 is a double-acting JIS compact cylinder with a 32mm bore and 35mm full stroke. An external threaded stop with a lock nut limits the extend end position, allowing you to fine-tune the usable extend travel from 15mm up to 35mm 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 0.5 MPa.
This model features a 16mm rod and PT1/8 porting. It includes fixed elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions. The body incorporates sensor grooves for magnetic switches, though this specific unit ships without a magnet. The external adjuster utilizes an M12x1.25 thread for precise positioning.
Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-20 Technical Specifications
| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-20 |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| 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 ACQJ32X35-20 Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC fixture during setup, compensating for varying raw material thicknesses without machining new stop blocks.
Assembly Line Changeover
Rapidly reposition the extend end point on an automated assembly press when switching between different product variants on the same conveyor.
Carton Sealing Tensioning
Fine-tune the pressing depth of a packaging flap folder to accommodate different carton profiles, ensuring perfect seals without changing parts.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-20 the Right Cylinder?
When sizing this 32mm bore, dropping down to a 25mm bore reduces the 0.5 MPa push force to 245.4N, while stepping up to a 40mm bore increases it to 628.3N. If your application requires a fixed extend position that never varies, a standard ACQ32 cylinder without the external stop will suffice. For this adjustable model, confirm your ordering essentials: 32mm bore, 35mm full stroke, 20mm adjuster window, female M8x1.25 rod-end thread, and whether you require the S magnet option for reed or solid-state switches.
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 ACQJ32X35-20 FAQ
The usable extend range is 15-35mm (35mm full stroke minus the 20mm window). Force is identical to a standard ACQ: push is 402.1N and pull is 301.6N at 0.5 MPa, push is 562.9N at 0.7 MPa, and maximum push is 82 kgf at 1.0 MPa.
An external M12x1.25 threaded screw with a lock nut limits the extend travel, shortening the stroke without changing piston area or force. The retract stroke is unaffected. The cylinder uses fixed NBR elastomer bumpers at both ends for deceleration, not adjustable air cushions.
