Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-50
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-50 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 ACQJ32X175-50
The AirTAC ACQJ32X175-50 is a double-acting JIS compact cylinder with an external extend stop, configured as a made-to-order long-stroke variant exceeding the 100mm standard maximum for this 32mm bore. An external M12x1.25 threaded adjuster and lock nut limit the rod extension, providing a usable extend range of 125 to 175mm. The retract stroke remains completely unaffected by this mechanism.
Because the piston area is unchanged, output force is identical to a standard ACQ of the same size, delivering 402.1N push and 301.6N pull at 0.5MPa. The unit relies on a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. It operates between 0.15 and 1.0MPa, and while it lacks a sensor magnet, the body retains magnetic-switch grooves for future automation upgrades.

| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-50 |
|---|---|
| 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 ACQJ32X175-50 Is Used
Machining Center Changeovers
Dial in the exact extend stop from 125 to 175mm during CNC fixture swaps without machining new spacer blocks.
Carton Erector Adjustments
Tune the pusher rod end position on the fly to accommodate varying box depths on a packaging line.
Press Brake Trial Stops
Safely set trial end positions for metal forming tasks, relying on the fixed elastomer bumper for deceleration.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-50 the Right Cylinder?
When sizing this 32mm bore actuator, stepping down to a 25mm bore yields 245.4N push at 0.5MPa, whereas stepping up to a 40mm bore provides 628.3N push. If your equipment never requires end-position tuning, a fixed-stroke ACQ cylinder will suffice and avoid the adjuster overhang. To order this long-stroke variant correctly, confirm the 32mm bore, 175mm full stroke, 50mm adjustment window, female M8x1.25 rod thread, and PT1/8 port. Note that a plain compact cylinder will drift and lose its load on air loss; specify an external rod lock or pilot-operated check valve if fail-safe holding is required.
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 ACQJ32X175-50 FAQ
This 32mm bore cylinder 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 full stroke is 175mm, and with the 50mm adjustment window, the usable extend range is 125 to 175mm.
An external M12x1.25 threaded screw with a lock nut mechanically limits how far the rod extends, shortening the stroke length without altering the piston area or force output. The cylinder uses fixed NBR elastomer bumpers for deceleration instead of adjustable air cushions, and while it lacks a sensor magnet, the body includes grooves for adding reed or solid-state switches.
