Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-30SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-30SB 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 ACQJ32X35-30SB
The AirTAC ACQJ32X35-30SB is a double-acting JIS compact cylinder featuring a 32mm bore and a 35mm full stroke. An external threaded stop with a lock nut limits the rod extension, providing a usable extend range of 5-35mm. Because the piston area remains unchanged, output force is identical to a standard ACQ of this size. The retract stroke stays unaffected by the adjuster.
This model includes a male M14x1.5 piston rod end for direct load coupling and a built-in magnet for position sensing. It uses a PT1/8 port and relies on fixed NBR elastomer bumpers at each end for end-of-stroke deceleration rather than adjustable air cushions. The external adjuster utilizes an M12x1.25 thread.

| 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 ACQJ32X35-30SB Is Used
Machining Fixture Stops
Dial in the exact clamping extension on a CNC machining fixture without swapping out cylinder hardware during setup.
Packaging Changeover
Adapt the pusher stroke length on the fly when switching between different carton sizes on a packaging line.
Assembly Press Positioning
Establish trial end positions for pressing small subcomponents, allowing precise depth tuning before final lockdown.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-30SB the Right Cylinder?
For sizing context, stepping down to a 25mm bore yields 245.4N push at 0.5MPa, while a 40mm bore provides 628.3N. If your application never requires altering the end position, a fixed-stroke ACQ cylinder is sufficient. When ordering this adjustable version, confirm the 32mm bore, 35mm full stroke, 30mm adjustment window, the S magnet option, and the B male rod 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 ACQJ32X35-30SB 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 30mm adjustment window allows the extend stroke to be fine-tuned within a 5-35mm usable range.
The M12x1.25 external stop mechanically limits rod extension, changing only the stroke length without reducing output force. Deceleration relies on fixed elastomer bumpers, and the built-in magnet works with both reed and electronic solid-state switches.
