Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-10SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-10SB 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 ACQJ32X175-10SB
The AirTAC ACQJ32X175-10SB is a double-acting, single-rod JIS compact cylinder built for applications requiring precise extend-end tuning. It features an external M12x1.25 threaded stop with a lock nut, allowing you to fine-tune the extend position on the machine without swapping parts. The usable extend range spans 165 to 175 mm, while the retract stroke remains completely unaffected. As a long-stroke made-to-order variant, it exceeds the 100 mm standard maximum for this bore, extending up to the 300 mm long-stroke limit.
Because the adjuster only limits travel and not piston area, the output force is identical to a standard ACQ of the same bore. You get 402.1 N of push force and 301.6 N of pull force at 0.5 MPa. The unit includes a male M14x1.5 rod-end thread (-B) for direct load coupling, a built-in piston magnet (-S) for electronic or reed switches, and fixed NBR elastomer bumpers at both ends rather than adjustable air cushions.

| 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 ACQJ32X175-10SB Is Used
CNC Fixture Clamping
Dial in the exact clamping extension on varying raw casting widths without machining custom stop collars.
Carton Sealing Stops
Adjust the pressing height on the fly during product changeovers to accommodate different box sizes.
Assembly Press Setup
Test and set precise trial end positions for pressing bearings without recalculating complex motion profiles.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-10SB the Right Cylinder?
When sizing this 32 mm bore model, consider the neighbouring bores: a 25 mm bore yields 245.4 N push at 0.5 MPa, while a 40 mm bore provides 628.3 N push. If your extend position never varies, a fixed-stroke ACQ cylinder suffices. For this adjustable model, confirm the 32 mm bore, 175 mm full stroke, 10 mm window, the -S magnet for sensing, and the -B male rod thread. Note that a plain ACQ-type cylinder will not hold a load on air loss; for fail-safe holding, specify an external rod lock or pilot-operated check valve.
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 ACQJ32X175-10SB FAQ
This cylinder delivers 402.1 N push and 301.6 N pull at 0.5 MPa, 562.9 N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The full stroke is 175 mm with a 10 mm window, giving a usable extend range of 165 to 175 mm.
No, the adjuster only shortens the extend stroke length; the force remains identical to a standard ACQ because the piston area is unchanged. The cylinder uses fixed elastomer NBR bumpers at each end for deceleration rather than adjustable air cushions.
