Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-20
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-20 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 80mm 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 ACQJ32X80-20
The AirTAC ACQJ32X80-20 is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut. This mechanism limits the extend end position, allowing you to fine-tune the usable extend range from 60 mm up to the full 80 mm stroke directly on your machine. The retract stroke remains completely unaffected by this adjustment.
Because the piston area stays the same, the output force is identical to a standard ACQ of this 32 mm bore, delivering 402.1 N push and 301.6 N pull at 0.5 MPa. The cylinder body incorporates fixed elastomer bumpers for end-of-stroke deceleration and includes standard magnetic-switch grooves, though this specific unit ships without a magnet. It uses a PT1/8 port and a 16 mm piston rod with an M8x1.25 female rod-end thread.

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 ACQJ32X80-20 Is Used
Machining Fixture Stops
Adjust the extend position on the fly to accommodate different workpiece heights on a CNC milling fixture without machining new stop collars.
Product Changeover Guides
Rapidly reconfigure the extend length on a packaging conveyor guide rail when transitioning between varying carton sizes.
Assembly Press Positioning
Dial in the exact 60 to 80 mm extend depth on an electronic assembly press during prototype runs to prevent damaging delicate components.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-20 the Right Cylinder?
When sizing this 32 mm bore actuator, consider the required extend travel and clamping force. If your application needs less push than the 402.1 N at 0.5 MPa provided here, stepping down to a 25 mm bore yields 245.4 N of push force. Conversely, demanding setups requiring more power should step up to a 40 mm bore, which generates 628.3 N. If your end position never varies, a fixed-stroke ACQ cylinder is sufficient. To order this adjustable version correctly, confirm the 32 mm bore, 80 mm full stroke, 20 mm window, female rod thread, and whether you need the -S magnet option for position 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 ACQJ32X80-20 FAQ
The usable extend range is 60-80 mm (80 mm full stroke minus the 20 mm window). 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 retract stroke remains fixed at 80 mm.
An external M12x1.25 threaded adjuster screw with a lock nut mechanically limits how far the rod extends. The piston area is unchanged, so the output force remains identical to a standard ACQ cylinder. The unit relies on fixed NBR elastomer bumpers for deceleration, not adjustable air cushions.
