Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-20B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-20B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 100mm 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 ACQJ32X100-20B
The AirTAC ACQJ32X100-20B is a double-acting JIS compact cylinder featuring an external extend-stroke adjuster. By turning the M12x1.25 stopper screw with its lock nut, you can fine-tune the usable extend range from 80 to 100 mm directly on your equipment. The retract stroke remains completely unaffected by this mechanism.
Because the piston area stays the same, output force is identical to a standard ACQ of this bore, delivering 402.1 N of push at 0.5 MPa. This variant includes a male M14x1.5 piston rod end for direct load coupling and relies on a fixed NBR elastomer bumper at each end for end-of-stroke deceleration. The body features integrated magnetic-switch grooves, though this specific unit 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 ACQJ32X100-20B Is Used
Machine Tending Setup
Dial in the exact 80 to 100 mm extension for varying part sizes on a CNC lathe loader without machining new spacers.
Product Changeover Stops
Adjust the extend stop on packaging lines to accommodate different carton lengths rapidly during format transitions.
Assembly Fixture Positioning
Set precise end positions for clamping modules in multi-product pallet fixtures, allowing quick adaptation for new runs.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-20B the Right Cylinder?
If you need slightly less push force at 0.5 MPa, the 25 mm bore yields 245.4 N, whereas stepping up to the 40 mm bore provides 628.3 N. A fixed-stroke ACQ32 is sufficient if your end position never varies. When ordering, verify the 32 mm bore, 100 mm full stroke, 20 mm adjustable window, the male M14x1.5 rod thread, and confirm no magnet is required since the -S option is absent.
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 ACQJ32X100-20B FAQ
The usable extend range is 80-100 mm (100 mm full stroke minus the 20 mm window). Force is identical to a standard ACQ: 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 limits the extend distance without altering the piston area or force. The cylinder uses a fixed elastomer bumper, not an adjustable air cushion. A plain ACQ-type does not hold its load on air loss; the rod drifts, so use an external rod lock or pilot-operated check valve for fail-safe holding.
