Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X80-100
The AirTAC Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X80-100 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø20mm bore and 80mm 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 ACQJ20X80-100
The AirTAC ACQJ20X80-100 is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. You can fine-tune the usable extend range from 0 up to 80mm directly on your machinery, while the retract stroke remains completely unaffected. Because the piston area stays the same, the output force is identical to a standard ACQ of this bore.
This 20mm bore actuator features a 10mm rod and an M5x0.8 port. It provides 157.1N of push force and 117.8N of pull force at 0.5 MPa, reaching a maximum push of 32 kgf at 1.0 MPa. The body includes fixed elastomer TPU bumpers at both ends for end-of-stroke deceleration and retains magnetic-switch grooves, though this specific SKU ships without a magnet.

| 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 ACQJ20X80-100 Is Used
Prototype Positioning
Dial in the exact extend stop during new machine commissioning without machining custom spacers or swapping cylinders.
Product Changeover
Quickly alter the extend endpoint to accommodate varying material thicknesses on a production line.
Adjustable Pressing
Set precise downward travel for pressing labels or light components, relying on the fixed bumper for the return stop.
Is the Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X80-100 the Right Cylinder?
If you require less push force, the 16mm bore variant offers 100.5N push at 0.5 MPa, whereas stepping up to the 25mm bore provides 245.4N. A fixed-stroke ACQ cylinder is sufficient if your extend position never needs adjustment. When ordering, confirm the 20mm bore, 80mm full stroke, 100mm adjustment window, female M5x0.8 rod thread, and whether you need the S magnet option for 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 ACQJ12~25 Adjustable Compact Cylinder ACQJ20X80-100 FAQ
It delivers 157.1N push and 117.8N pull at 0.5 MPa, 219.9N push at 0.7 MPa, and a maximum push of 32 kgf at 1.0 MPa. The full stroke is 80mm, but the external M8x1.25 adjuster allows you to shorten the extend stroke by up to 100mm, yielding a usable extend range of 0-80mm.
No, the adjuster only limits the extend stroke length, so the force remains identical to a standard ACQ. The cylinder uses fixed elastomer bumpers for deceleration and will not hold a load if air pressure is lost, so an external rod lock is needed for fail-safe holding.
