Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X35-10S
The AirTAC Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X35-10S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø20mm bore and 35mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.

About the Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X35-10S
The AirTAC ACQJ20X35-10S is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend stroke. You get a usable extend range of 25-35mm (the 35mm full stroke minus the 10mm window), letting you fine-tune the end position directly on the machine. The retract stroke remains unaffected by this adjustment.
Because the piston area is unchanged, force output is identical to a standard ACQ bore 20. You retain the fixed elastomer bumper at each end and the integrated magnet for reed or solid-state switches. The M8x1.25 adjuster thread allows precise mechanical positioning without altering pneumatic pressure.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø20 mm |
| Full stroke | 35 mm |
| Adjuster thread | M8×1.25 |
| Port size | M5×0.8 |
| 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 | M5×0.8 (F) / M8×1.25 (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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 118 N |
| 0.7 MPa | 220 N | — |
| Max (@1.0 MPa) | 32 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 ACQJ12~25 Adjustable Compact Cylinder ACQJ20X35-10S Is Used
Fixture Positioning
Dial in the extend stop for varying jig heights on a machining center without swapping out cylinder hardware.
Product Changeover
Adjust the extend stroke on a packaging line to accommodate different carton sizes quickly and accurately.
Trial End Positions
Set precise clamping limits during test fixture development, tweaking the 25-35mm range until the optimal contact point is found.
Is the Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X35-10S the Right Cylinder?
If you need less push force, the bore 12 model provides 56.5N at 0.5MPa, while stepping up to bore 25 yields 245.4N. Choose this ACQJ20X35-10S when your application requires exact end-position tuning within a 25-35mm window. If a fixed 35mm extend position is always sufficient, a standard ACQ20X35 costs less. Confirm your ordering details: 20mm bore, 35mm full stroke, 10mm window, S magnet, and female M5x0.8 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 ACQJ12~25 Adjustable Compact Cylinder ACQJ20X35-10S FAQ
The usable extend range is 25-35mm. Force is identical to a standard ACQ bore 20: push is 157.1N and pull is 117.8N at 0.5MPa, push is 219.9N at 0.7MPa, and max push is 32kgf at 1.0MPa.
The external M8x1.25 threaded stop with lock nut limits extension length only; retract stroke and force remain unchanged. The cylinder uses a fixed elastomer bumper, and the -S magnet works with reed or solid-state switches.
