Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X25-30B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X25-30B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 25mm 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 ACQJ32X25-30B
The AirTAC ACQJ32X25-30B is a double-acting JIS compact cylinder featuring a male-thread piston rod end (M14x1.5) that couples directly to your load. An external threaded stop with a lock nut limits the extend end position, providing a usable extend range of 0-25 mm from a 25 mm full stroke. The retract stroke remains unaffected by this adjustment.
Because the piston area is unchanged, the output force is identical to a standard ACQ of this bore, delivering 402.1 N push and 301.6 N pull at 0.5 MPa. The body incorporates sensor grooves for reed or solid-state switches, though this specific unit ships without a magnet. It relies on a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion.

| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X25-30B |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 25 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 ACQJ32X25-30B Is Used
Machining Fixture Stops
Dial in the exact clamping extension on a CNC machining fixture without machining new spacer blocks.
Product Changeover Pushers
Quickly reposition the extend endpoint on a packaging line pusher when switching between different carton widths.
Assembly Press Trial
Safely test and incrementally adjust the pressing depth of a pin insertion station during initial setup runs.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X25-30B the Right Cylinder?
Selecting this 32 mm bore provides 402.1 N push at 0.5 MPa, sitting between the 20 mm bore (157.1 N push) and the 40 mm bore (628.3 N push). A fixed-stroke ACQ is sufficient if your end position never requires tuning, but the external M12x1.25 adjuster here allows on-machine end-position changes without swapping parts. Confirm your ordering essentials: 32 mm bore, 25 mm full stroke, 30 mm window, male rod thread (-B), and no magnet. Note that a plain cylinder does not hold its load on air loss; use an external rod lock or pilot-operated check valve for fail-safe holding.
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 ACQJ32X25-30B 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 usable extend range is 0-25 mm (25 mm full stroke minus the 30 mm window), while the retract stroke remains unaffected.
An external M12x1.25 threaded stop with a lock nut limits the extend stroke, allowing on-machine tuning without changing parts. The cylinder uses fixed NBR elastomer bumpers at both ends, not adjustable air cushions. The body has sensor grooves for reed or solid-state switches, but this model ships without a magnet (-S omitted).
