Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-75SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-75SB 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 ACQJ32X175-75SB
The AirTAC ACQJ32X175-75SB is a double-acting JIS compact cylinder with a 32 mm bore and a 175 mm full stroke. Because this is a long-stroke made-to-order variant (exceeding the 100 mm standard maximum for this bore), it provides extended travel for applications requiring deeper reach. An external threaded stop with a lock nut lets you limit the extend end position, yielding a usable extend range of 100 to 175 mm. The retract stroke remains completely unaffected.
Output force is identical to a standard ACQ of this size, as the adjuster alters travel length only. At 0.5 MPa, it delivers 402.1 N of push force and 301.6 N of pull force. This unit includes the -S magnet for reed or solid-state switches and the -B male M14x1.5 rod-end thread. Deceleration relies on a fixed NBR elastomer bumper at each end, not an adjustable air cushion.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| 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 ACQJ32X175-75SB Is Used
Assembly Press Stroke Tuning
Dial in the exact extend end position for pressing bearings during new product changeovers without machining new hard stops.
Variable-Length Diverter
Adjust the pusher extend limit on a packaging conveyor to match different carton widths on the fly.
CNC Lathe Loader Setup
Fine-tune the rod extension when feeding bar stock into a lathe chuck, allowing quick setup for varying part lengths.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-75SB the Right Cylinder?
If your application needs less push at 0.5 MPa, stepping down to a 25 mm bore yields 245.4 N, while moving up to a 40 mm bore provides 628.3 N. A fixed-stroke ACQ is sufficient if your end position never varies. For this model, confirm the 32 mm bore, 175 mm full stroke, 75 mm adjust window, the -S magnet, and the -B male M14x1.5 rod thread when ordering.
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 ACQJ32X175-75SB FAQ
It provides 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 75 mm adjust window, giving a usable extend range of 100 to 175 mm.
An external M12x1.25 threaded stop with a lock nut limits the extend stroke, letting you set the end position on the machine. The adjuster changes travel length only, so force is identical to a standard ACQ. A fixed NBR elastomer bumper handles deceleration at stroke ends.
