Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X175-10S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X175-10S 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 ACQJ40X175-10S
The AirTAC ACQJ40X175-10S is a double-acting JIS compact cylinder featuring an external extend-stop mechanism. A threaded rod with a lock nut lets you set the outward travel anywhere within a 165 to 175 mm usable range, while the return stroke remains fixed at 175 mm. Because the piston area is unaltered by this stop, you get the exact same thrust as a regular ACQ of this size.
This unit is a long-stroke made-to-order variant, exceeding the 100 mm standard maximum for a 40 mm bore. It incorporates a 16 mm piston rod, PT1/8 porting, and a female M8x1.25 rod-end thread. The integrated -S magnet supports reed or solid-state sensing, and NBR elastomer bumpers handle end-stop deceleration.

| Bore size | Ø40 mm |
| Full stroke | 175 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 ACQJ40X175-10S Is Used
Machining Fixture Tuning
Dial in the exact clamping extension on a CNC fixture during prototype runs, shaving the 10 mm window off the full 175 mm travel to avoid crashing the spindle.
Product Changeover Diverter
Shift a packaging line diverter stop out by a few millimeters when switching to a larger carton size, using the lock nut to set the new extend endpoint quickly.
Assembly Press Setup
Find the optimal pressing depth on an electronic component insertion station by adjusting the outward stop on the fly without swapping out the entire actuator body.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X175-10S the Right Cylinder?
If your application only needs 628.3 N of push force at 0.5 MPa, this 40 mm bore is the right fit. Stepping down to a 32 mm bore yields 402.1 N, whereas moving up to a 50 mm bore provides 981.8 N. If you never need to modify the end position, a standard fixed-stroke ACQ cylinder will suffice. When ordering this adjustable version, confirm the 175 mm full stroke, 10 mm window, magnet option, and female rod thread.
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 ACQJ40X175-10S FAQ
It provides 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push at 0.7 MPa, and a maximum push of 128 kgf at 1.0 MPa. The full stroke is 175 mm with a 10 mm adjustable window, yielding a usable extend range of 165-175 mm. The piston rod is 16 mm, the port is PT1/8, the female rod-end thread is M8x1.25, and the external adjuster thread is M12x1.25.
No, the adjuster only limits the extend length, so thrust remains identical to a standard ACQ. Deceleration is handled by fixed NBR elastomer bumpers at both ends, not an adjustable air cushion. The -S magnet allows position detection using either reed or electronic solid-state switches.
