Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-100SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-100SB 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 ACQJ32X175-100SB
The AirTAC ACQJ32X175-100SB is a double-acting JIS compact cylinder with a 32mm bore and a 175mm long-stroke design, exceeding the standard 100mm maximum for this bore size. It features an external M12x1.25 threaded stop with a lock nut on the rod-end side, allowing you to fine-tune the extend end position directly on the machine. The usable extend range spans 75-175mm, while the retract stroke remains completely unaffected.
Because the internal piston area is unchanged, the output force is identical to a standard ACQ of this bore, delivering 402.1N push and 301.6N pull at 0.5 MPa. This made-to-order variant includes a built-in piston magnet for electronic or reed switches (-S) and a male M14x1.5 threaded rod end (-B) for direct load coupling. Deceleration relies on a fixed NBR elastomer bumper at each end, rather than 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 ACQJ32X175-100SB Is Used
Machining Fixture Stops
Dial in exact clamping reach on a CNC machining fixture without machining new spacer blocks when part dimensions change.
Packaging Line Diverters
Alter the extension of a sorting gate on a packaging conveyor to accommodate varying carton widths rapidly.
Assembly Press Trial
Establish precise press-in depths for bearings on an assembly line by testing different extend end positions before locking the nut.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-100SB the Right Cylinder?
When sizing this unit, consider the neighbouring bores: a 25mm bore yields 245.4N push at 0.5 MPa, whereas a 40mm bore provides 628.3N. This 32mm model offers 402.1N push, striking a balance for medium-duty tasks. If your application never requires stroke adjustments, a fixed-stroke ACQ32X175 will suffice and avoids the external hardware. To order this cylinder correctly, confirm the 32mm bore, 175mm full stroke, 100mm adjuster window, the -S magnet requirement, and the -B male 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 ACQJ32X175-100SB FAQ
This cylinder has a 175mm full stroke with a 100mm adjustment window, yielding a usable extend range of 75-175mm. The force equals a standard ACQ: 402.1N push and 301.6N pull at 0.5 MPa, 562.9N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The port size is PT1/8.
The M12x1.25 external threaded stop and lock nut limit how far the rod extends, shortening the extend stroke without changing the piston area, so force remains identical to a standard ACQ. The fixed elastomer bumper decelerates the load near the end of travel, but the cylinder will not hold a load on air loss; use an external rod lock for fail-safe holding.
