Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-30S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-30S 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 ACQJ40X150-30S
The ACQJ40X150-30S is a double-acting JIS compact cylinder with a 150mm stroke and an external extend stop. A threaded adjuster with a lock nut lets you set the extend end position anywhere in the 120 to 150mm range on the machine, while the retract stroke remains unaffected. This 40mm bore generates 628.3N push and 527.8N pull at 0.5MPa, matching standard ACQ output exactly because the piston area is unchanged.
This unit features a -S piston magnet compatible with reed or solid-state switches, operating at 30-500mm/s. It is a long-stroke made-to-order variant, exceeding the 100mm standard maximum for this bore. The body uses fixed NBR elastomer bumpers at each end for deceleration, meaning external shock absorbers are recommended for high-energy loads.

| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-30S |
|---|---|
| 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 ACQJ40X150-30S Is Used
Machining Fixture Clamping
Dial in the exact clamping reach on a CNC lathe during setup, shortening the extend up to 30mm to accommodate different raw material lengths without swapping actuators.
Packaging Line Changeover
Rapidly reposition the product pusher end stop for new carton sizes on a filling line, using the external M12x1.25 adjuster to hit the precise 120-150mm ejection point.
Assembly Press Positioning
Test and set trial end positions for pressing bearings on an automated line, fine-tuning the stroke depth on the equipment while maintaining the full 628.3N clamping force.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-30S the Right Cylinder?
Selecting this 40mm bore actuator involves balancing force and reach: it yields 628.3N push at 0.5MPa, sitting between the 32mm bore (402.1N push) and the 50mm bore (981.8N push). If your extend endpoint never varies, a fixed-stroke ACQ cylinder provides the same power without the adjuster. When ordering, confirm the 150mm stroke, 30mm adjustment window, PT1/8 port, M8x1.25 female rod thread, and the required -S 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 ACQJ40X150-30S FAQ
This 40mm bore cylinder has a 150mm stroke with a 30mm adjustable window, giving a usable extend range of 120-150mm. 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 force is identical to a standard ACQ because the adjuster only limits stroke length.
An external threaded stop with a lock nut limits the extend stroke, leaving the retract stroke unaffected. It uses fixed NBR elastomer bumpers at both ends for deceleration rather than adjustable air cushions, so external shock absorbers are advised for high-speed loads. The -S magnet works with reed or electronic switches for position sensing.
