Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X20-10S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X20-10S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 20mm 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 ACQJ32X20-10S
The ACQJ32X20-10S is a double-acting JIS compact cylinder with a 32mm bore and 20mm full stroke. An external M12x1.25 threaded stop and lock nut restricts the extend end position, yielding a usable extend range of 10 to 20mm. The retract stroke remains completely unaffected by this adjustment. Because the piston area stays constant, output force equals that of a standard ACQ counterpart.
This unit includes a female M8x1.25 rod-end thread, a PT1/8 port, and a 16mm piston rod. A factory-fixed NBR elastomer bumper decelerates the load at each end without requiring manual cushion adjustment. The -S suffix equips the piston with a magnet compatible with both reed and solid-state electronic switches.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 20 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 ACQJ32X20-10S Is Used
Machining Fixture Stops
Dial in the exact extend position between 10 and 20mm when clamping raw castings of varying widths on a CNC milling table.
Assembly Changeover
Rapidly reposition the extend end-stop for a new product run on an automated assembly line without swapping out cylinder hardware.
Prototype Positioning
Establish the ideal trial extend endpoint for a new testing rig, locking the M12x1.25 adjuster nut once the optimal reach is found.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X20-10S the Right Cylinder?
When sizing this 32mm bore, a 25mm option provides 245.4N push at 0.5MPa, while a 40mm unit yields 628.3N. If your machine never needs end-position tuning, a fixed-stroke ACQ32x20 is simpler. To order correctly, confirm the 20mm full stroke, 10mm adjuster window, S magnet option, and female M8x1.25 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 ACQJ32X20-10S FAQ
It delivers 402.1N push and 301.6N pull at 0.5MPa, and 562.9N push at 0.7MPa, with a maximum push of 82kgf at 1.0MPa. The 20mm full stroke features a 10mm adjustable window, allowing the extend range to be set anywhere from 10 to 20mm.
No, the external stop only limits the extend length, so force remains identical to a standard ACQ. Deceleration is handled by fixed NBR elastomer bumpers at both ends, not adjustable air cushions, and the retract stroke stays completely unaffected.
