Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-100
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-100 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 ACQJ40X150-100
The ACQJ40X150-100 is a double-acting JIS compact cylinder featuring a 150 mm full stroke and a 100 mm adjustment window, yielding a usable extend range of 50 to 150 mm. A threaded external stop with a lock nut permits precise on-machine end-position tuning without swapping parts. The retract stroke remains completely unaffected by this mechanism.
Because the internal piston area stays constant, output force matches a standard ACQ bore 40 exactly: 628.3 N push and 527.8 N pull at 0.5 MPa. This made-to-order long-stroke variant exceeds the 100 mm standard maximum for this bore. It utilizes a 16 mm rod, PT1/8 porting, and fixed elastomer bumpers at both ends for end-of-stroke deceleration.

| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-100 |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| 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 ACQJ40X150-100 Is Used
Machining Fixture Positioning
Dial in the exact clamping reach on a CNC fixture during new product trial runs without machining custom spacers.
Packaging Diverter Setup
Adjust the diverting arm endpoint on the fly to handle varying carton lengths on a packaging line.
Assembly Press Stroke Tuning
Fine-tune the pressing depth of an assembly station during product changeovers to prevent part damage.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-100 the Right Cylinder?
When sizing this actuator, consider the neighboring bores: the ACQJ32 provides 402.1 N push, while the ACQJ50 yields 981.8 N at 0.5 MPa. If your extend position never varies, a fixed-stroke ACQ40 suffices. For this model, confirm the 40 mm bore, 150 mm full stroke, 100 mm window, female M8x1.25 rod thread, and note this unit ships without a magnet. Remember that a plain compact cylinder drifts on air loss; add an external rod lock for fail-safe load holding.
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 ACQJ40X150-100 FAQ
Force is identical to a standard ACQ: 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push at 0.7 MPa, and 128 kgf max push at 1.0 MPa. The usable extend range is 50-150 mm because the 100 mm window shortens the 150 mm full stroke.
An M12x1.25 threaded adjuster with a lock nut limits the extend length, changing stroke only without affecting piston area or force. Deceleration relies on fixed elastomer bumpers, not adjustable air cushions. This unit lacks a magnet for sensors.
