Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X45-40B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X45-40B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 45mm 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 ACQJ32X45-40B
The AirTAC ACQJ32X45-40B is a double-acting JIS compact cylinder featuring an external 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 forward range of 5 to 45 mm from a 45 mm full stroke. The retract stroke remains completely unaffected by this adjustment.
Because the piston area is unchanged, output force is identical to a standard ACQ of this bore, yielding 402.1 N push and 301.6 N pull at 0.5 MPa. The unit retains its compact C-clip body and fixed NBR elastomer bumpers at each end. Note that this specific configuration ships without a magnet, though the body still features magnetic-switch grooves for adding external sensors 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 ACQJ32X45-40B Is Used
Machine Tending Fixtures
Dial in the exact extend end position during initial fixture setup without machining new spacers or swapping components on the fly.
Product Changeover Stops
Quickly alter the forward reach to accommodate varying part heights or lengths on a packaging line during rapid product transitions.
Prototype End Positions
Safely test trial end stops and clamp depths on an R&D assembly rig, fine-tuning the 5 to 45 mm range until kinematics are proven.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X45-40B the Right Cylinder?
If you need less force, the 25 mm bore delivers 245.4 N push at 0.5 MPa, whereas stepping up to the 40 mm bore provides 628.3 N push. If the forward end position never varies, a fixed-stroke ACQ cylinder is simpler and sufficient. When ordering this adjustable unit, confirm the 32 mm bore, 45 mm full stroke, 40 mm window, male M14x1.5 rod thread, and PT1/8 port.
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 ACQJ32X45-40B FAQ
It 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 5 to 45 mm (a 45 mm full stroke minus a 40 mm window).
The external M12x1.25 threaded stop with lock nut limits only the extend length, meaning force is identical to a standard ACQ. Fixed NBR bumpers decelerate the load near stroke ends. A plain ACQ-type cylinder will not hold its load on air loss, so use an external rod lock for fail-safe holding.
