Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-40B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-40B 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 ACQJ32X35-40B
The AirTAC ACQJ32X35-40B is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. You can fine-tune the usable extend range from 0-35 mm on the machine without swapping parts, while the retract stroke remains unaffected. It features a 32 mm bore, a 16 mm rod, and a male M14x1.5 rod-end thread that couples directly to your load.
Because the adjuster alters stroke length only, the force is identical to a standard ACQ of this bore. It delivers 402.1 N push and 301.6 N pull at 0.5 MPa, rising to 562.9 N push at 0.7 MPa, with a maximum push of 82 kgf at 1.0 MPa. The body includes fixed NBR elastomer bumpers at each end for end-of-stroke deceleration and retains sensor grooves, though this specific unit ships without a magnet.

| 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 |

| 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 ACQJ32X35-40B Is Used
Machining Fixture Clamping
Dial in the exact clamping extension on a CNC machining fixture to accommodate raw material thickness variations without machining custom spacers.
Assembly Line Product Changeover
Rapidly reposition the extend stop for different product heights on a modular assembly line, cutting changeover time between production runs.
Prototyping End Positions
Test and trial various extend end positions on new packaging equipment to find the optimal pressing depth before finalizing the design.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-40B the Right Cylinder?
If you need less push force, the 25 mm bore variant provides 245.4 N push at 0.5 MPa; stepping up to the 40 mm bore yields 628.3 N push at 0.5 MPa. A fixed-stroke ACQ is sufficient if your extend end position never requires adjustment. When ordering this cylinder, confirm the 32 mm bore, 35 mm full stroke, 40 mm adjuster window, the male M14x1.5 rod thread, and that no magnet is included.
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 ACQJ32X35-40B FAQ
The force is identical to a standard ACQ: 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 full stroke is 35 mm with a 40 mm adjustment window, giving a usable extend range of 0-35 mm. The operating pressure is 0.15-1.0 MPa, port size is PT1/8, and the external adjuster thread is M12x1.25.
An external threaded stop with a lock nut limits how far the rod extends, changing only the stroke length and not the piston area, so force remains unchanged. The retract stroke is unaffected. Fixed NBR elastomer bumpers decelerate the load at stroke ends, but this plain cylinder will not hold its load on air loss; use an external rod lock or pilot-operated check valve for fail-safe holding.
