Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X175-30
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X175-30 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 175mm 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 ACQJ40X175-30
The AirTAC ACQJ40X175-30 is a double-acting JIS compact cylinder engineered as a long-stroke, made-to-order variant, exceeding the standard 100mm maximum for this bore with a 175mm total travel. It features an external threaded stop with a lock nut on the rod-end side, allowing you to fine-tune the extend end position on the machine without swapping parts. The usable extend range spans 145 to 175mm, while the retract stroke remains completely unaffected.
Because the piston area stays constant, the output force equals that of a standard ACQ, delivering 628.3N push and 527.8N pull at 0.5MPa. The unit incorporates fixed elastomer bumpers at both ends for end-of-stroke deceleration and retains magnetic-switch grooves in the body. This model ships without a magnet and uses a female-threaded piston rod end (M8x1.25) with PT1/8 ports.

| 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 ACQJ40X175-30 Is Used
Multi-Product Changeover Stops
Quickly modify the extend endpoint from 145 to 175mm on packaging lines to accommodate varying carton sizes without fabricating new hard stops.
Trial End Positions
Dial in the exact clamping depth on a test fixture by adjusting the external M12x1.25 stopper nut, ensuring material is secured without deformation.
Setup-Varying Fixtures
Adapt the pusher stroke on automated assembly machines for different product heights, relying on the 628.3N push force at 0.5MPa to seat components.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X175-30 the Right Cylinder?
When sizing this 40mm bore, stepping down to a 32mm bore yields a 402.1N push at 0.5MPa, whereas stepping up to a 50mm bore provides 981.8N of push force. If your application requires a fixed extend length that never varies, a standard ACQ cylinder will suffice and avoid the made-to-order lead time. For this adjustable variant, confirm the 40mm bore, 175mm full travel, 30mm adjuster window, female rod thread, and whether you require the -S magnet option for solid-state or reed switch sensing.
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 ACQJ40X175-30 FAQ
The usable extend range is 145-175mm (175mm full stroke minus the 30mm window). It provides a push force of 628.3N and a pull force of 527.8N at 0.5MPa, 879.6N push at 0.7MPa, and a maximum push of 128kgf at 1.0MPa.
The adjuster is an external M12x1.25 threaded stop with a lock nut that limits how far the rod extends, shortening the extend stroke without changing the piston area. Therefore, the force remains identical to a standard ACQ, and the retract stroke is unaffected. The cylinder relies on fixed elastomer bumpers for deceleration, so for high-energy loads, an external shock absorber is recommended.
