Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-75B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-75B 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 ACQJ32X175-75B
The ACQJ32X175-75B is a double-acting, single-rod JIS compact cylinder featuring a 32 mm bore and a 175 mm non-standard long stroke. An external threaded stop with a lock nut limits the extend end position, providing a usable extend range of 100 to 175 mm. The retract stroke remains completely unaffected. Because the piston area is unchanged, the output force is identical to a standard ACQ of this bore.
This made-to-order variant supplies a male-thread piston rod end (M14x1.5) for direct load coupling. It incorporates fixed elastomer NBR bumpers at each end for end-of-stroke deceleration rather than adjustable air cushions. The body retains magnetic-switch grooves, though this specific configuration ships without a magnet.

| 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 |

| 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 ACQJ32X175-75B Is Used
Machining Fixture Stops
Dial in the exact extend position of workpiece clamps on a CNC milling fixture without machining new spacer blocks.
Product Changeover Diverters
Adjust the extend stroke of a conveyor sorting gate to accommodate different package lengths rapidly during line changeovers.
Packaging Tamping Heads
Fine-tune the packing depth of a tamping head on a filling machine to settle various product volumes precisely.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-75B the Right Cylinder?
When sizing this actuator, note that the 32 mm bore yields 402.1 N push force and 301.6 N pull force at 0.5 MPa. Stepping down to a 25 mm bore drops the push force to 245.4 N, while moving up to a 40 mm bore increases it to 628.3 N. If the exact extend length is fixed and never requires on-machine tweaking, a standard ACQ32 fixed-stroke cylinder would suffice. To order this adjustable version correctly, confirm the 32 mm bore, 175 mm full stroke, 75 mm adjustable window, the male B rod thread, and the PT1/8 port size.
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 ACQJ32X175-75B FAQ
The usable extend range is 100-175 mm (175 mm full stroke minus up to 75 mm). The force is identical to a standard ACQ 32: push is 402.1 N and pull is 301.6 N at 0.5 MPa, push is 562.9 N at 0.7 MPa, and maximum push is 82 kgf at 1.0 MPa.
An external M12x1.25 threaded stop with a lock nut mechanically limits the extend length without altering the piston area, so force remains unchanged. Deceleration relies on fixed NBR elastomer bumpers, not adjustable air cushions. Note that a plain ACQ-type cylinder does not hold its load on air loss; for fail-safe holding, use an external rod lock or pilot-operated check valve.
