Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-50S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-50S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm 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 ACQJ32X175-50S
The ACQJ32X175-50S is a double-acting JIS compact cylinder featuring a 175mm stroke and an external extend stop. A threaded rod-end adjuster with a lock nut lets you fine-tune the forward end position on the machine, yielding a usable extend range of 125-175mm. The retract stroke remains completely unaffected by this mechanism.
Because the piston area stays constant, output force equals a standard ACQ of the same bore: 402.1N push and 301.6N pull at 0.5MPa. This 32mm bore unit is a long-stroke made-to-order variant, exceeding the 100mm standard maximum. It includes a built-in magnet for sensing and fixed NBR elastomer bumpers at both ends.

| Bore size | Ø32 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 302 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 ACQJ32X175-50S Is Used
Machining Center Changeovers
Dial in the exact clamping reach on CNC fixtures during product changeovers without machining new spacer blocks.
Variable Carton Sealing
Adjust the tamping head extension on packaging lines to accommodate different box heights rapidly on the fly.
Extended Reach Sorting
Set trial end positions for diverter arms on long-stroke conveyor transfers to perfectly route varying package profiles.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-50S the Right Cylinder?
When sizing this actuator, the adjacent 25mm bore yields 245.4N push, while the 40mm bore provides 628.3N push at 0.5MPa, helping you verify if 402.1N is optimal. If your equipment never requires end-position adjustments, a fixed-stroke ACQ cylinder will suffice. To order, confirm the 32mm bore, 175mm full stroke, 50mm window, the S magnet option, and the M8x1.25 female rod-end 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 ACQJ32X175-50S FAQ
It delivers 402.1N push and 301.6N pull at 0.5MPa, 562.9N push at 0.7MPa, and a maximum push of 82kgf at 1.0MPa. The usable extend range is 125-175mm, adjustable via the 50mm window. Retract stroke is unaffected.
An M12x1.25 threaded stop with a lock nut limits the forward extension distance, changing stroke length only. The force remains identical to a standard ACQ. The cylinder uses fixed NBR bumpers, and the S magnet works with reed or solid-state switches.
