Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-20
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-20 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 150mm 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 ACQJ32X150-20
The ACQJ32X150-20 is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. You can fine-tune the usable extend range from 130 mm up to the full 150 mm stroke directly on the machine, while the retract stroke remains unaffected. This 150 mm unit is a long-stroke, made-to-order variant exceeding the 100 mm standard maximum for a 32 mm bore.
Because the piston area is unchanged, force remains identical to a standard ACQ of this size, delivering 402.1 N push at 0.5 MPa. The body features fixed elastomer bumpers at each end for end-of-travel deceleration and includes sensor grooves. This specific configuration ships without a magnet and uses a female-threaded piston rod end (M8x1.25).

| 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 ACQJ32X150-20 Is Used
Machining Fixture Stops
Dial in the exact extend position within the 130-150 mm window during CNC fixture setup without swapping physical stopper parts.
Product Changeover Diverters
Adjust the stroke on packaging line diverters on-the-fly to handle varying carton lengths on a shared conveyor belt.
Assembly Press Trial
Safely test new end positions for a pressing operation in a factory automation cell before locking down the final travel distance.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-20 the Right Cylinder?
When sizing this unit, consider the neighbouring bores: a 25 mm bore provides 245.4 N push at 0.5 MPa, while a 40 mm bore yields 628.3 N. The 32 mm bore here provides a balanced 402.1 N push and 301.6 N pull at 0.5 MPa. If your application requires a fixed end position every cycle, a standard ACQ cylinder without the external adjuster will suffice. To order, confirm the 32 mm bore, 150 mm full stroke, 20 mm adjustable window, female rod thread, and whether you need the -S magnet option for reed or solid-state switches.
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 ACQJ32X150-20 FAQ
The push force is 402.1 N and pull is 301.6 N at 0.5 MPa (562.9 N push at 0.7 MPa, max 82 kgf at 1.0 MPa). The usable extend range is 130-150 mm via a 20 mm window. The external adjuster uses an M12x1.25 thread. This 150 mm unit is a long-stroke variant.
The external threaded stop with a lock nut limits the extend stroke length only, so force is identical to a standard ACQ. The cylinder uses fixed elastomer bumpers, not an adjustable air cushion. A plain cylinder does not hold loads on air loss; for fail-safe holding, use an external rod lock or pilot-operated check valve.
