Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X300-10B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X300-10B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 300mm 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 ACQJ32X300-10B
The ACQJ32X300-10B is a double-acting JIS compact cylinder built for applications requiring precise extend positioning. It features an external M12x1.25 threaded stop with a lock nut that limits the outward stroke. You can fine-tune the end position directly on your equipment across a 290 to 300 mm usable range without swapping parts. The retract stroke remains completely unaffected by this adjustment.
This long-stroke made-to-order variant exceeds the standard 100 mm maximum for a 32 mm bore, extending to 300 mm. Because the piston area is unchanged, output force matches a standard ACQ exactly, delivering 402.1 N push and 301.6 N pull at 0.5 MPa. The unit incorporates a 16 mm rod with a male M14x1.5 thread for direct load coupling, fixed NBR elastomer bumpers at both ends, and a PT1/8 port. Note that this specific configuration ships without a piston magnet, though the body retains sensor grooves for adding external switches if needed later.

| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| 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 ACQJ32X300-10B Is Used
Machining Fixture Stops
Dial in the exact extend position of a 300 mm clamping arm on a CNC machining center to accommodate raw material thickness variations without reprogramming motion controllers.
Product Changeover Diverter
Adjust the stroke end point on a packaging conveyor diverter by up to 10 mm to cleanly route different carton sizes during quick production line changeovers.
Assembly Press Trial
Set precise trial end positions for a pressing operation in electronics assembly, allowing operators to tweak the 290 to 300 mm reach on the machine floor before finalizing the cycle.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X300-10B the Right Cylinder?
Selecting this model requires verifying that your layout accommodates a 300 mm stroke, which is a non-standard long-stroke configuration for the 32 mm bore. If your application only needs a fixed reach, a standard ACQ series cylinder would suffice and likely cost less. When sizing force, stepping down to a 25 mm bore yields 245.4 N push at 0.5 MPa, whereas stepping up to a 40 mm bore provides 628.3 N. Confirm your ordering essentials: 32 mm bore, 300 mm full stroke, 10 mm adjuster window, male M14x1.5 rod thread, and no magnet.
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 ACQJ32X300-10B FAQ
This cylinder provides 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 290 to 300 mm, achieved by shortening the 300 mm full stroke up to the 10 mm window.
The external M12x1.25 threaded stop with lock nut mechanically limits the extend length without altering piston area, so force remains identical to a standard ACQ. Deceleration relies on fixed NBR elastomer bumpers, not adjustable air cushions. A plain compact cylinder does not hold its load on air loss; for fail-safe positioning, install an external rod lock or pilot-operated check valve.
