Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X60-50
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X60-50 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 60mm 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 ACQJ32X60-50
The AirTAC ACQJ32X60-50 is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that restricts the extend stroke. You can fine-tune the outward end position on the machine itself without swapping parts, yielding a usable extend span of 10 to 60mm from the 60mm full stroke. The retract movement remains completely unaffected by this adjustment.
Because the piston area stays constant, output force mirrors a standard ACQ equivalent, delivering 402.1N push and 301.6N pull at 0.5MPa. The unit integrates fixed elastomer bumpers rather than adjustable air cushions, and the body includes sensor grooves for tracking, though this specific configuration ships without a magnet. Operating pressure spans 0.15 to 1.0MPa, with a PT1/8 port and a 16mm piston rod.

| 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 ACQJ32X60-50 Is Used
Machining Fixture Clamps
Dial in the exact clamping reach on a CNC fixture during prototype runs, allowing the rod to extend between 10 and 60mm to accommodate varying part thicknesses without machining new stops.
Carton Sealing Flaps
Adjust the folding arm stroke on a packaging line to match different carton heights, using the external M12x1.25 adjuster to set the precise extend endpoint on the fly.
Assembly Line Stops
Regulate product positioning stops on a conveyor during product changeover, fine-tuning the outward stroke while relying on the fixed elastomer bumper to decelerate the load at the end of travel.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X60-50 the Right Cylinder?
When sizing this 32mm bore, dropping to a 25mm option lowers the push force to 245.4N at 0.5MPa, while stepping up to a 40mm bore raises it to 628.3N. If your application never requires altering the extend endpoint, a fixed-stroke ACQ cylinder suffices and simplifies the setup. To order this adjustable variant correctly, confirm the 32mm bore, 60mm full stroke, 50mm window, female M8x1.25 rod thread, and whether you need the S magnet option for electronic or reed switch sensing.
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 ACQJ32X60-50 FAQ
It provides 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 60mm, but the external adjuster allows you to shorten the extend stroke by up to 50mm, giving a usable extend range of 10 to 60mm.
No, the threaded stop only changes the extend stroke length, not the piston area, so force remains identical to a standard ACQ. This plain cylinder does not hold its load if air is lost; the rod drifts and the fixed NBR bumper only decelerates near stroke end, so add an external rod lock for fail-safe holding.
