Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X75-20
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X75-20 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 75mm 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 ACQJ32X75-20
The AirTAC ACQJ32X75-20 is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend stroke. You can fine-tune the forward end position on the machine, yielding a usable extend range of 55-75 mm from the 75 mm full stroke. The retract stroke remains unaffected. Because the piston area stays constant, output force is identical to a standard ACQ of this bore.
This 32 mm bore unit pushes 402.1 N and pulls 301.6 N at 0.5 MPa. It uses a PT1/8 port and a 16 mm rod with an M8x1.25 female rod-end thread. The body incorporates sensor grooves for reed or solid-state switches, though this specific SKU ships without a magnet. Deceleration relies on a fixed NBR elastomer bumper at each end rather than an adjustable air cushion.

| Bore size | Ø32 mm |
| Full stroke | 75 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 ACQJ32X75-20 Is Used
Multi-Format Machining Stops
Dial in the exact extend position between 55 and 75 mm on a CNC loading station when switching between raw material blank sizes.
Variable Depth Carton Forming
Adjust the rod extension on the fly to accommodate different box depths without physically replacing the cylinder or changing mounting spacers.
Assembly Line Changeover
Fine-tune the forward pusher stroke during product family transitions on a conveyor line to prevent crushing delicate new components.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X75-20 the Right Cylinder?
Selecting this 32 mm bore provides 402.1 N push at 0.5 MPa; stepping down to a 25 mm bore yields 245.4 N, while moving up to a 40 mm bore provides 628.3 N. If your application never requires end-position shifts, a fixed-stroke ACQ cylinder suffices. When ordering this adjustable variant, confirm the 75 mm full stroke, the 20 mm window, the default female rod thread, and whether you need the -S magnet option for sensing.
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 ACQJ32X75-20 FAQ
This 32 mm bore cylinder delivers a push force of 402.1 N and a pull force of 301.6 N at 0.5 MPa, with a push of 562.9 N at 0.7 MPa. The maximum push is 82 kgf at 1.0 MPa. The 20 mm adjustment window provides a usable extend range of 55-75 mm.
An external M12x1.25 threaded stop with a lock nut limits the forward stroke length only, meaning the output force is identical to a standard ACQ. The retract stroke is unaffected. End-of-travel deceleration relies on fixed elastomer bumpers, not adjustable air cushions, so external shock absorbers are recommended for high-energy loads.
