Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-40B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-40B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm 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 ACQJ40X150-40B
The AirTAC ACQJ40X150-40B is a double-acting JIS compact cylinder built for specialized long-stroke applications. It features a 150mm total stroke, which exceeds the 100mm standard maximum for this 40mm bore, making it a made-to-order variant. An external threaded stop with a lock nut lets you limit the extend end position, providing a usable extend range of 110-150mm. The retract stroke remains entirely unaffected by this mechanism.
Because the piston area is unchanged, output force equals a standard ACQ of the same bore, delivering 628.3N push and 527.8N pull at 0.5MPa. This model includes a male M14x1.5 piston rod end (-B) for direct load coupling, PT1/8 porting, and an M12x1.25 adjuster thread. It uses fixed NBR elastomer bumpers at each end for end-of-stroke deceleration rather than adjustable air cushions. The body retains magnetic-switch grooves, though this specific SKU ships without a magnet.

| Bore size | Ø40 mm |
| Full stroke | 150 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 ACQJ40X150-40B Is Used
Multi-Fixture Setup Tuning
Dial in the exact extend end position for varying jig heights on a machining line without swapping out cylinder hardware.
Product Changeover Stops
Adjust the physical stop distance on-the-fly when handling different package lengths on a packaging conveyor.
Trial End Positions
Safely test extend reach limits on new automated assembly equipment before locking the external nut into final position.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-40B the Right Cylinder?
When sizing this unit, consider the 128kgf maximum push at 1.0MPa against your dynamic load. If your application requires less force, stepping down to a 32mm bore yields 402.1N push at 0.5MPa, while stepping up to a 50mm bore provides 981.8N push at 0.5MPa. If your extend position never needs on-machine variation, a fixed-stroke standard ACQ cylinder will suffice. For ordering, confirm the 40mm bore, 150mm full stroke, 40mm adjustable window, male rod thread (-B), and note the absence of the magnet option.
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 ACQJ40X150-40B FAQ
The usable extend range is 110-150mm. It delivers 628.3N push and 527.8N pull at 0.5MPa, 879.6N push at 0.7MPa, and a maximum push of 128kgf at 1.0MPa. The adjuster changes stroke length only, so force is identical to a standard ACQ.
An external M12x1.25 threaded stop with a lock nut limits the extend distance without affecting the retract stroke. Fixed NBR elastomer bumpers decelerate the piston at each end. Note that a plain ACQ-type cylinder will drift on air loss; use an external rod lock for fail-safe holding.
