Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X250-50
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X250-50 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 250mm 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 ACQJ32X250-50
The AirTAC ACQJ32X250-50 is a double-acting, single-rod JIS compact cylinder built for on-machine extend-position tuning. An external M12x1.25 threaded stop with a lock nut restricts forward travel, providing a usable extend range of 200 to 250 mm from a 250 mm full stroke. The retract distance remains completely unaffected. This unit is a long-stroke, made-to-order variant, as the 250 mm length exceeds the 100 mm standard maximum for a 32 mm bore.
Because the internal piston area stays constant, output force equals a standard ACQ of identical size. You get 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 capacity of 82 kgf at 1.0 MPa. The body incorporates fixed elastomer NBR bumpers at each end for end-of-travel deceleration rather than adjustable air cushions. It features a 16 mm rod, a PT1/8 port, and a female M8x1.25 rod-end thread.

| 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 ACQJ32X250-50 Is Used
Machining Fixture Stops
Dial in the exact 200 to 250 mm clamping extension on a CNC machining fixture without machining new spacers or swapping cylinders.
Product Changeover Diverter
Shift the extend end position rapidly on a packaging line conveyor when transitioning between different carton widths.
Prototype Press Positioning
Establish the ideal trial end position on a small pneumatic press, locking the lock nut once the exact 32 mm bore force is verified.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X250-50 the Right Cylinder?
If you need less push at 0.5 MPa, the 25 mm bore yields 245.4 N; for greater force, step up to the 40 mm bore providing 628.3 N. A fixed-stroke ACQ is adequate if your end stop never varies. This non-magnet model lacks the -S option, though the body retains sensor grooves for adding reed or solid-state switches if you source a magnet separately. Confirm your ordering essentials: 32 mm bore, 250 mm full stroke, 50 mm adjust window, female rod thread, and PT porting.
Quick checklist

- ✓ 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 ACQJ32X250-50 FAQ
This 32 mm bore cylinder delivers 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 250 mm, but the external M12x1.25 adjuster allows you to shorten the extend stroke by up to 50 mm, yielding a usable extend range of 200 to 250 mm.
The external threaded stop and lock nut mechanically limit how far the rod extends, changing only the stroke length and not the piston area. Therefore, the force remains identical to a standard ACQ. The cylinder uses fixed elastomer bumpers for deceleration rather than adjustable air cushions, and this non-magnet model ships without a sensor magnet despite having switch grooves.
